laptop battery

1, lithium-ion battery nominal voltage 3.7V (3.6V), charging cut-off voltage 4.2V (4.1V, the batteries under the brands have different designs). (Li-ion batteries is the norm: lithium ion secondary battery)

2, to the requirements of lithium-ion rechargeable laptop battery (GB/T18287 2000 norms): First of all, constant current charge, that is, a certain current, and battery charging voltage as the process of gradually increased, when the battery terminal voltage to reach 4.2V (4.1V), Constant change Charge for the charging voltage, that is, a certain voltage, current batteries based on the degree of saturation, with the charging process to continue to gradually reduce, when reduced to 0.01C, that the termination charge. (C batteries based on current nominal capacity of a control method that, if the battery is a 1000mAh capacity, 1C charge current is 1000mA, attention mA is not mAh, 0.01C is 10mA.) Of course, that standard is 0.01 C5A, here I simplified.

3, 0.01C why that was the end of the charge: This is a national standard GB/T18287-2000 provided as well as the discussions. Previously it was generally for an end to 20mA, the Ministry of Posts and Telecommunications YD/T998-1999 industry standards provided for in the same way, that is, no matter how much battery capacity, to stop all current 20mA. GB 0.01C provided help to more full charge, through the identification of a party manufacturers benefit. In addition, the national standard provides for the charging time is not more than 8 hours, that is, even if not yet reached 0.01C, 8 hours, and that the end of the charge. (No problem, the quality of the batteries should be 8 hours to reach 0.01C, the poor quality of the battery, wait and meaningless)

4, What is the difference between battery 4.1V or 4.2V: consumers do not have the distinction, depending on batteries manufacturer of the product specifications. Some brands of batteries are 4.1V and 4.2V common, such as A & TB (Toshiba), the domestic manufacturers is the basic 4.2V, but there are exceptions, such as Tianjin is the power of God 4.1V (but also by a 4.2V).

5, the rechargeable batteries of 4.1V to 4.2V happen: will increase the capacity of the battery, with a good feeling, and standby time, but will reduce ibm battery life. For example, the original 500, reduced to 300. By the same token, to the 4.2V batteries have been sufficient, it will lower its short-lived. Lithium-ion batteries is very delicate.

6, since the battery inside a protective plate, we can rest assured that it had: No, because the board to protect the cut-off parameter is 4.35V (this is good, the bad to 4.4 to 4.5V), protection of the board is to meet in the event, If every time charge-off, the battery will decay quickly.

7, much of the charge current is appropriate: In theory, the smaller of the more beneficial to the battery. But you can not order a battery charge, such as 3 days now. GB provides low-rate charge is 0.2C (standard arbitration charge), but also to the top of the battery capacity of 1000mAh, for example, is 200mA, so we have this PA2487UR can be estimated more than 5 hours to full charge. (MAh = current capacity mA × time h)

State technical supervision departments to identify capacity lithium-based high-rate charge of 1C to 0.2C low discharge rate, time to calculate the value of capacity, the number of Test 5, 1st capacity to reach the end of the trial. (5 is the chance that if the first pass a test on the back of the 4th does not) allow for testing before the first cycle in advance, in order to 1C is the current charge that 4.2V to cease, and not behind the constant pressure to 0.01 C process, but not 14 hours.

8, Li-ion batteries can withstand much of the charge current: factory tests can be very high, but the elevation ratio requirement for the country 1C, also above the cell, for example, more than 1 hour can be filled. Such a charge current, battery can bear it? For the current lithium-ion batteries, is the only Xiaoyi Si. There are no national standards for the Chargers, enforced by the Ministry of Posts and Telecommunications is the industry standard YD/T998 1999 / 2, which provides for the current charger not to be more than 1C.

9, what is provided for in life: to put it simply refers to the ThinkPad T60 battery at 1C charge N after, 1C discharge, the capacity dropped to 70% at this time of the N is the life. Is not to say that 300 can also be used, the 301 can not be used. GB provides life shall be not less than 300. We usually do not detect the use of the conditions so harsh, life will be longer.

In the mobile phone, both from a technical point of view or from the assessment of price considerations, the laptop battery is very important. Value today, the market is sales of mobile phones, used batteries has been completed from a nickel to cell lithium battery transition. Perhaps it is because of cell phone battery had just completed a nickel to cell lithium battery revolution, the people's awareness of lithium batteries are not uniform and in many cases incorrect to say and practice is quite popular. As a result, know a little knowledge of lithium batteries, lithium batteries have the right to use it is very necessary.

First, the type of lithium battery:
At present, the market used rechargeable batteries are nickel metal hydride (Ni-MH) and lithium-ion (Li-ion) are two types. Lithium-ion batteries have been in mass production of liquid lithium-ion battery (LiB) and lithium-ion polymer battery (LiP) two. Therefore, in many cases, the battery mark on the Li-ion and lithium-ion battery is a must. But that is not necessarily liquid lithium-ion battery, is also possible that the polymer lithium-ion battery.
Lithium-ion battery is a lithium sony battery improved version of the product. Lithium batteries have a long time ago, but the lithium is a highly active (remember that the its position in the periodic table?) Of the metal, it is not safe when used often in charge when burning, the burst , Then there is the improved version of the lithium-ion batteries by adding the element lithium can inhibit the active ingredients (such as cobalt, manganese, etc.) so that the lithium power to achieve real security, efficient and convenient, and the old lithium batteries also Basically eliminated. As to how to distinguish them from the battery on the logo will be able to identify, lithium batteries for Li, lithium-ion battery for Li-ion. Now, notebook and mobile phone use of the so-called "lithium batteries", in fact, are lithium-ion battery.
The basic structure of modern batteries, including cathode, anode and electrolyte of the three elements. As a battery, lithium-ion battery with the same three elements. Lithium-ion technology in general or the use of inorganic colloidal liquid electrolyte, it needs to accommodate case solid combustible active ingredient, which increased the battery's weight and cost, but also limits the size and design flexibility. In general, liquid lithium-ion secondary battery is the minimum thickness of 6mm, and then to reduce the more difficult.
The so-called polymer lithium-ion batteries in three of the main structure at least one or more polymer materials used as the main battery system.
A new generation of polymer lithium-ion polymer batteries in the extent of the already very high, so the shape can be shaped and thin (the thinnest 0.5 mm), of any size and any shape, and greatly increased PCGA-BP2V design flexibility , In order to meet product demand, made in any shape and capacity of the battery. At the same time, lithium-ion polymer battery unit of energy than current lithium-ion batteries in general increased by 50% of its capacity, charge and discharge characteristics, security, operating temperature range, cycle life and environmental performance in areas such as lithium-ion batteries are relatively large The rate increase.
Currently on the market by sales of liquid lithium-ion (LiB) in the over-charging the battery case, thus easily lead to the breakdown of the fire safety situation, it is very dangerous, so to install the necessary protection to ensure that the cell line IC will be no over - Charge. The polymer lithium-ion battery, this type of cell relatively liquid lithium-ion battery in terms of good-resistant properties of charge and discharge, so the protection of Canada's IC circuit requirements can be relaxed. Also in charge, the polymer lithium-ion batteries can be recharged using IC will be current with the lithium-ion rechargeable battery used in CCCV (Constant Currert-Constant Voltage) charge means the time required for comparison, can shorten the waiting time for many.

Second, mobile phone manufacturers of lithium batteries on the application of
In recent years, although almost all manufacturers have a preference for lithium-ion battery, but the world's major mobile phone manufacturers the option of VGP-BPS5 or have their own characteristics and habits, for example, in the same period in history:
Nokia: Ni-MH (Ni-MH) batteries, LiB (liquid lithium-ion) batteries did not use the LiP (polymer lithium-ion) batteries.
Ericsson: Ni-MH battery, LiB battery, LiP battery.
Motorola: Ni-MH battery, LiB battery did not use the battery LiP.
It is not difficult to find, from the first choice for mobile phone LiP polymer lithium-ion batteries on this matter, Ericsson reflect their true qualities of a pioneer in mobile phone technology. According to the information I find to indicate that the current lithium-ion polymer battery manufacturing plant for the main JPSONY, Panasonic, GS, and other companies, production in 2000 amounted to 21,000,000, of which 50% of Ericsson mobile phone package. In 2002 into today's lithium-ion battery in the other cell phone makers of mobile phones has also been widely used and popular. But lithium-ion polymer batteries used, is far from the reach of all mobile phone manufacturers of products that have been popular, is also widely used Youdaishiri.
On the other hand, although many advantages of lithium-ion batteries, but there are also shortcomings, such as higher prices and fewer charge-discharge and so on. Li-ion battery charging and discharging of 400-600, only the number of times, specially to improve the product but also a number of 800. The nickel-metal hydride rechargeable batteries to 700 the number of times over, some of the good quality products, charge and discharge up to 1,200 times, such a comparison, Ni-MH PCGA-BP71 life than lithium batteries. In addition the price of nickel-metal hydride batteries are also much lower than lithium batteries. Moreover, strictly speaking, lithium batteries have the same memory effect, but it's very low memory effect is basically negligible.
In view of this, there is no perfect battery.

Third, the use of lithium-ion battery
This is part of the focus of this article, we discuss three points.
1, for a new battery charge
In the use of lithium batteries should be noted that for a period of time after the battery is placed into hibernation, lower than normal capacity at this time, the time has also come to shorten. However, lithium batteries can easily activated, as long as after 3-5 times the normal charge-discharge cycle of the battery can be activated, the resumption of normal capacity. As the battery lithium own characteristics, its decision is almost no memory effect. Therefore, cell phone users in a new lithium battery in the activation process does not require special methods and equipment. Not only is the theory that, from my own practice, from the very beginning, the use of standard methods of charging that "activation" is the best way.
Lithium batteries for the "activation", a large number of claims: the time to charge more than 12 hours, repeated three times to do in order to activate the battery. "The first three necessary and sufficient to charge more than 12 hours", it is obvious from the nickel battery (such as nickel-cadmium and nickel metal hydride) inherited. This is why it can be said is the beginning of miscommunication. Lithium batteries and nickel battery charge and discharge characteristics of a very big difference, but also very clear to tell you that I have had access to all the serious official stressed that all technical information and charge-off will discharge lithium batteries, especially lithium liquid Ion battery causing great harm. According to the charge and therefore the best time and method of charging standards, in particular for not more than 12 hours of super-long charge. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of charging.
In addition, the lithium battery in the phone or VGP-BPS5 charger will automatically stop after a charge, there is no electricity nickel charger for 10 hours the so-called "trickle" charge. In other words, if your lithium batteries in full, on the white charger is also sufficient. And we can not guarantee that no one battery charge and discharge protection circuit features and never change the quality of safety, so your batteries will be in the long-term hovering on the brink of danger. This is also another charge against the chief reason.
In addition to certain mobile phones, the charge for more than a certain amount of time, if not remove the charger, this time not only to stop charging system, will be the beginning of discharge - charge cycle. This is perhaps the manufacturer has its own purpose, it is clear that on the phone and battery / charger is the life span of a negative. At the same time, long charging would take a long time, often at night, and to our country's power grid situation, at night in many parts of the relatively high voltage, but also volatile. Said earlier, the lithium battery is very delicate than nickel in the electric charge and discharge aspects of fluctuations in the capacity of resistance is much less, so this brings additional risk.
In addition, can not be ignored other aspects of a lithium battery that is not the same for over-discharge, over-discharge of lithium batteries is also very unfavorable. This leads to the following question.
2, in normal use when the charge should be
In our forums, often see this as the number of charging and discharging is limited, so should the cell phone PCGA-BP71 power used up as much as possible and then charge. But I find on a lithium-ion battery charge and discharge cycle test table, on the life cycle of figures is as follows:
Life cycle (10% DOD):> 1000 times
Life cycle (100% DOD):> 200 times
DOD is the depth of the discharge of which the initials. Can be seen from the table, the number of rechargeable and about the depth of discharge, 10% DOD at the time of the life cycle than 100% DOD's a lot longer. Of course, if the actual charge equivalent to the total capacity of the relative: 10% * 1000% * 100,100 = 200 = 200, which is the complete charge and discharge, or better than some, but in front of friends do say that some of the amendments: normal Under the circumstances, you should have a reservation in accordance with the remaining battery power and then run out of filling the principle of charging, but if your battery is expected in the first 2 days you can not adhere to the whole day, should start on time charge, of course, if you are willing to back A charger to the office and when Bielun.
And you need to charge in order to cope with the anticipated upcoming busy communications will lead to an important event, even if there are a lot of battery power over time, then you just charge ahead of time because you do not have a real loss "1" sub-charge cycle life , That is, "0.x" times, but often this will be a very small x.
The remaining battery power and then run out of charge to the principle does not mean that you go to the extreme. And charging the same length of a widespread view that "as far as possible the cell phone batteries run out of power, it is best to use automatic shutdown." This is only a matter of fact on nickel batteries, to avoid occurrence of memory effect, unfortunately, it is also spread of lithium batteries on this. It has been too low because the cell phone vaio battery warning appears, do not continue to use the charge has been used in automatic shutdown of the case. The outcome of this case, the phone was in charge of the boot in and there was no response, had to give customer service overhaul. In fact, this is due to the battery as a result of excessive discharge and led to the low voltage that does not have the normal charge of the boot and conditions.
3, Li-ion battery for mobile phones in the right way
To sum up, I lithium batteries used in mobile phone charging and discharging of the most important tips are:
1, in accordance with the standards and procedures, charging time, even before the three to do so;
2, When the phone prompts when electricity is too low and should start charging as much as possible in a timely manner;
3, lithium batteries do not need to activate the special method, in a normal cell phone use in lithium batteries would be natural to activate. If you insist on spreading the use of "three times before the 12-hour long activation charge" approach, in fact there will not be the effect.
As a result, all 12 hours long pursuit of the lithium batteries and rechargeable cell phone used in automatic shutdown, are wrong. If you are used to be in accordance with the wrong done, please correct in a timely manner, perhaps not too late.
Of course, sony battery and chargers to protect themselves and control the quality of a good circuit, for the protection of lithium batteries or have guaranteed. Therefore, understanding the rules of the charge is the key, in some cases also may make some concessions. For example, you found your cell phone the night before bed charge, you can also start charging before going to bed. The crux of the matter is that you should know what is the right thing to do, and not in accordance with the deliberately wrong to do.

Now use the notebook more and more people, as the notebook one of the main components of lithium laptop battery problems have also increased. So how should make good use of the laptop's lithium batteries do? Is to grasp two points:
     1. Due to current red discharge.
2. To minimize the discharge less than the over-charge or discharge.
While the battery is a consumable, lithium-ion battery is no exception. However, no one wants to use the battery up the fine spirit of God, not the age that you snap on the end, no one wants to own the very beginning, half dead battery does not pull a living, this has been the rub in 2023, making good You realize how little value is the case, you do not say that?
Well, get down to business, following the battery began to speak. To explain, is limited to lithium-ion battery.
Appropriate to charge and discharge current
Literature in general and the state on the standard lithium-ion battery that the lithium-ion battery charge current should be between 0.2C to 1C. It is said that the capacity of the battery charge current, such as your battery is 4AH, then the 0.2C charge current is 0.2X4 = 0.8A, in other words, the charge current should be between 0.8 to 4A. In general, in charge current to the extent permitted by the smaller the better, rechargeable lithium-ion compaq battery to start charging current stage should be, in my IBM R31, this current is 2.8A or so, which is equivalent to 0.7C, is charging its own circuit Control, can not be set. This indicator does not charge more than the standard, but do more, especially when using the battery capacity decline for some time after the charge current may be more than 1C. Now the length of time charge notebook users have also become targets regardless of the manufacturers were forced to charge current set so high.
So the first step is to reduce the charge current. I have friends working in the laboratory, a variety of readily available equipment, where he is on trial for a moment. Power output in the first string on a try resistance, the outcome of the current is reduced, but became intermittent charge, which is not a good thing. Through trial and error, 4 Ohm is a more ideal value, this time around 0.8A charge current is, very stable. This is only run through the machine's current power supply interface, the battery charge current estimated number of large, it should be slightly larger than 0.2C. Specific to a different machine, this value may be different. With the addition of the increase in battery voltage, charge current will be reduced, but decreased only slightly less than 0.05A. In such a state of charge, charging circuit seems to be not working, the battery indicator light is not bright. Such as the battery voltage up to 12.6V, charging circuits came into play into the Presario 2500 battery trickle charge, at this time whether the series has resistance does not matter, the charge current by the charge control circuit, the last full charge after the end of the circuit automatically charge. The entire charge time is about 5.5 hours, if not resistance, charging time is about 3.5 hours.
Lithium-ion batteries is very precious, good charge control circuit is necessary. This charging method can reduce the charge current, battery life, while at the same time the use of the books of the original charge of the charge control circuit, it is also relatively simple to achieve, just buy a plug (from the power supply into books The kind, it is best to buy two, referred to the back of a method also used to good quality) and a can of resistance, resistance attention to the larger head, above, after all, there are about 2W of power Otherwise, it would be more heat resistance, the best use of their constant resistance to be a wire, the wire resistance of the resistance and temperature has nothing to do basic. But the shortcomings of this approach is obvious, that is not in charge of the work at the same time with books. Another charge when there will be a strange phenomenon, I do not write omitted here, you try to know, the good news is this phenomenon into the trickle charge after the state disappeared. Charging time is not a big deal, anyway, before the charge to sleep at night, wake up the next day on the charge Well, of course, if you are a person who goes to bed to bed or short-time special, it is a different matter.
Small charge current issue is resolved, the issue is now the turn of the discharge. In fact, this is difficult, after all, the book is designed to work as discharge current state of work varies, referred to here is limited to the methods designed to resume the operation of the Presario 700 battery capacity.
Start machines, power management settings do not always sleep (standby) and hibernation (hibernate), as are most other power-saving mode, including the CPU speed, hard drive shut down, turn off the display, and so on, and TP in the management process Do not have to shut down some of the hardware, such as sound cards and so on, and then open the battery status display window, to run in front! ! ! The closure of other programs, in particular, screen saver and the other from time to time to run the program! ! Do not use the machine, do not close the lid and let the battery discharge end (not to discharge the minimum value set to 0, I set up 3%). Display and hard drive shut down after the discharge current is about 0.5A, this is my IBM R31 can be achieved at the minimum discharge current, discharge the battery to set the minimum value after the machine will automatically shut down. Continue to discharge the entire time about more than 4 hours, according to your battery capacity may be different, this time to sleep is also a way to use the pass.
Well, the last to stress that the above-mentioned method is not dead, especially the discharge, there are ten time will be able to do so, otherwise the battery still doing? Charging the best use of small current charge, of course, if the battery urgent need for a direct power supply to plug inserted in the book on it.
I used this method of battery, put a charge 14 times the capacity has been maintained at over 45, and the design of the battery capacity is 43.2, which is also declining, but this release Filling time after the restoration of.
Speaking at the beginning of the two points, one appropriate charge and discharge, and the other is not to discharge less than the charge, discharge following a look at how to solve the problem of lack of charge on it:
To minimize the discharge less than the over-charge or discharge
In fact, a very good solution to the excessive discharge, not to terminate the limits of the discharge can be so low, I have been using 3%.
Often do not use batteries may be a long time, such as the battery remaining 70%, if the power switch, then the  Presario 900 battery is automatically recharged, there will be no such a cycle, although battery life is not a cycle in order to set the absolute number of dead, But always it will reduce the capacity of the battery, lithium-ion battery was no memory effect, but it is just a memory effect it is relatively low. Unfortunately, IBM did not provide the solution to the shortage of charge-discharge method, but provides a solution to this problem. And that is what I found on the R31 may not necessarily suitable for other machines, but the method should also be more or less the same, you try not to forget after it posted for all to share.
R31 charging circuit based on the situation of the power to decide whether to charge the battery. Power output voltage is 16V, the error of plus or minus 0.2V, if the voltage lower than 15.5V, so not to charge the battery charging circuit, and the book can work, which is provided by IBM to solve the problem. But this is the basis of vulnerability, as if the lower voltage 15.2V, books will be converted to use battery-powered, plug in the power supply even if the books will be of no avail. In other words, we can toss the space is 0.3V.
If you can find a 15.5V, over the current 3A switching power supply, then the problem is solved, otherwise please continue to look down.
The power to reduce the output voltage 0.5V is not an easy thing, the series resistance is not ideal because of the resistance as the current size of the voltage changes. I use the diode rectifier to permit the adoption of the current 2A above, otherwise the heat pipe. Rectifier diode forward voltage drop in the 0.7 to 0.5V, just to meet the requirements. Now this type of electronic tubes in the market are so high, the prices of less than 2 yuan. Specific to a different book may be different, it is best to install on-hand when there is a digital multimeter Test. Pipe is being in the series of power output, and then followed his own to buy a power plug inserted in the book. Then the anti-diode does not matter, be it the script does not work, and then in turn connected to it.

Like, power output voltage drop of 0.5V or so, if the drop too much, the book will switch to the battery, if the drop too low, the book will charge the Presario R3000 battery, in particular how much you want to book their own tried to know.
Of course, if your battery has been full of this circuit there is no need, you can not have it, directly to the power output in the next book on it.
Come to an end, the beginning of the two issues are resolved. Now you see the results of the test, it is estimated that in the book different results could be different, the best ones to take a circuit to try to avoid it took 10 innocent money :-)
Finally, I wish you good luck! You make good use of lithium batteries it!
To remind:
In the modified plug when the mistake is easy to engage in anti-polar (diodes engage in anti-polarity does not matter), so you must double-check by measuring multimeter and a different color of the wire connection is negative F4809A. I do not know engage in anti-polarity power supply will not burn the books, did not try!

First, when the storage power loss. Xinhua refers deficit state did not use the battery charge in a timely manner. Loss of idle state power longer, more serious damage to the laptop battery.

Second, the test on a regular basis. In the process, if electric cars continued the trip mileage in a short period of time all of a sudden drop in more than 10 kilometers, then the battery is likely to at least a piece of broken cell battery appears, softened plate, the plate active substances, such as falling short-circuit phenomenon . At this point, the batteries should be repaired in time to professional bodies to inspect, repair and distribution group.

Third, to avoid high-current discharge. Electric cars at the starting line, manned, uphill, please use pedal power to help avoid a momentary high-current discharge. High-current discharge easily lead to the creation of lead sulfate crystallization, to the detriment of the physical properties of the sony battery plate.

Fourth, the right to master the charging time.
In the process, according to the charging time to grasp the actual situation, in general batteries are recharged at night, with an average time of 8 hours. If the shallow discharge, the battery will soon be filled, the charge will continue to have sufficient, and that leads to cell loss, fever, to reduce battery life. Therefore, the battery discharge to a depth of 60% -70%, a charge the best power.

Five to prevent exposure. Electric cars is prohibited under the sun exposure. High temperature environment will increase the pressure on the internal battery by batteries pressure limiting valve automatically opens, is a direct consequence of the increase in the loss of water, batteries, PCGA-BP71 and excessive water loss will inevitably trigger cell activity decreased to accelerate the plate to soften, charging shell Body heat, from drums, such as deformation of fatal injury.

Six to avoid charge when Heat pull the plug. Charger output plug loose contact surface oxidation, and other phenomena will lead to Plug Charging hot, the heat too long may lead to short-circuit charging plug directly damage the charger and bring unnecessary loss. So when they found out that the situation should be cleared in a timely manner or replacement connector oxide.

First of all, the repeated charge from the battery will not have damage red repeated discharge of the battery is not damaged, as a result of active elements lithium and no memory effect, the element lithium battery manufacturers red discharge could be repeated. We now The majority (90%) also thought a few years ago to retain the popular Ni-MH laptop battery in the shadow, because the nickel element itself is not active, and with elements of electronic memory effect, that is: the last memory depth of the red discharge! So, if not to run out of batteries or charging for a long time (to stimulate the full nickel element - because of their inactive), it can not achieve the best results charge, the general in charge of the time or how many hours a night!

     However, the comrades have changed. We are now using the element lithium, the element in the natural world can not stand on its own, can only exist in the compound, you can access the periodic table, the element lithium is a very short half-life, and no Memory effect, the lithium batteries used in the course of time can not be completely washed and electrical discharge, as long recharge itself would be very active element in the e-saturated state of vigorous exercise took place at the same time there is an explosion of fresh produce, that is, : The best time charge for 2-4 hours, preferably not more than 4 hours (active elements, soon to stimulate charge, charge the appropriate time to reduce, even if this is the first time is rechargeable as long as 2 hours to 4 hours , As a result of lithium elements do not need to have been activated, the charge for a long time but the impact on the element lithium in the process of charging and discharging of the level of activity), by the way rechargeable lithium ibm laptop battery, charging process will be in a half-hour or 2 Man-hours have been found at this time, just half an hour and then washed, because charging voltage is the first complete red, followed by electronic charge after about half an hour slower! When electricity is best not to fully recharge depleted because of the light, the element lithium-needed response to the need to reverse the lack of compounds, not fully charged, resulting in decreased battery capacitor!

     Therefore, in all, cell phone lithium battery is a modern invention of the human cell, and its notebook computer \ MP3, and other electronics in the battery is the same, basically do not have to hell with the charge and discharge, or the technology developed Today, all day long in order to recharge the battery headaches, Tai Wo today the development of electronic technology adapted ah, the creators are not willing to, so at ease with it, said so much, is to let you know, summed up the contents of lithium batteries As follows: eNet is a forum for professional mobile phone forum, set up under various brand mobile phone discussion forum, and cell phone games, mobile phone software, cell phone themes, cell phone stand-by pictures, phone book, phone Brush package, mobile phone ring tones, mobile phone Download video, eNet Forum brings together a large number of mobile phone users to use mobile phones to exchange experiences, such as the purchase of mobile phone discussion forum for the exchange of information

     1. 2-4 hour charge time (not too long a time would adversely affect ThinkPad X60 battery life and the danger)

     2. Can not charge for the first time a long time, and usually charge the same can be (not to enter the nickel-metal hydride batteries errors)

     3. Can not fully use photovoltaic (completely used up, the battery life is also affected)

     A lithium battery to discharge the depth of the number of times it will be several times more than the bad on the 4. To use, quick to see no electricity, the lack of sleep with the red on the can is full of the best, it does not matter dissatisfied with the red !

     As with the use of necessary and sufficient, with the charge with the use! However, this lithium battery inventor of the slogan, and if the nickel-metal hydride rechargeable batteries, like the case of trouble, who invented more than a lot of poor stability of the Ni-MH F4809A lithium ah! The main value is less than the lithium batteries it easy!

First of all, the repeated charge from the battery will not have damage red repeated discharge of the battery is not damaged, as a result of active elements lithium and no memory effect, the element lithium battery manufacturers red discharge could be repeated. We now The majority (90%) also thought a few years ago to retain the popular Ni-MH laptop battery in the shadow, because the nickel element itself is not active, and with elements of electronic memory effect, that is: the last memory depth of the red discharge! So, if not to run out of batteries or charging for a long time (to stimulate the full nickel element - because of their inactive), it can not achieve the best results charge, the general in charge of the time or how many hours a night!

However, the comrades have changed. We are now using the element lithium, the element in the natural world can not stand on its own, can only exist in the compound, you can access the periodic table, the element lithium is a very short half-life, and no Memory effect, the lithium batteries used in the course of time can not be completely washed and electrical discharge, as long recharge itself would be very active element in the e-saturated state of vigorous exercise took place at the same time there is an explosion of fresh produce, that is, : The best time charge for 2-4 hours, preferably not more than 4 hours (active elements, soon to stimulate charge, charge the appropriate time to reduce, even if this is the first time is rechargeable as long as 2 hours to 4 hours , As a result of lithium elements do not need to have been activated, the charge for a long time but the impact on the element lithium in the process of charging and discharging of the level of activity), by the way rechargeable lithium ibm laptop battery, charging process will be in a half-hour or 2 Man-hours have been found at this time, just half an hour and then washed, because charging voltage is the first complete red, followed by electronic charge after about half an hour slower! When electricity is best not to fully recharge depleted because of the light, the element lithium-needed response to the need to reverse the lack of compounds, not fully charged, resulting in decreased battery capacitor!

Therefore, in all, cell phone lithium battery is a modern invention of the human cell, and its notebook computer \ MP3, and other electronics in the battery is the same, basically do not have to hell with the charge and discharge, or the technology developed Today, all day long in order to recharge the battery headaches, Tai Wo today the development of electronic technology adapted ah, the creators are not willing to, so at ease with it, said so much, is to let you know, summed up the contents of lithium batteries As follows: eNet is a forum for professional mobile phone forum ThinkPad T30 battery, set up under various brand mobile phone discussion forum, and cell phone games, mobile phone software, cell phone themes, cell phone stand-by pictures, phone book, phone Brush package, mobile phone ring tones, mobile phone Download video, eNet Forum brings together a large number of mobile phone users to use mobile phones to exchange experiences, such as the purchase of mobile phone discussion forum for the exchange of information

1. 2-4 hour charge time (not too long a time would adversely affect battery life and the danger)

2. Can not charge for the first time a long time, and usually charge the same can be (not to enter the nickel-metal hydride batteries errors)

3. Can not fully use photovoltaic (completely used up, the battery life is also affected)

A lithium battery to discharge the depth of the number of times it will be several times more than the bad on the 4. To use, quick to see no electricity, the lack of sleep with the red on the can is full of the best, it does not matter dissatisfied with the red !

As with the use of necessary and sufficient, with the charge with the use! However, this lithium battery inventor of the slogan, and if the nickel-metal hydride rechargeable batteries, like the case of trouble, who invented more than a lot of poor stability of the Ni-MH ThinkPad X60 battery lithium ah! The main value is less than the lithium batteries it easy!

Digital cameras rely mainly on battery power, but if you do not use a match or do not pay attention to save the laptop battery, the battery will not take you long, exhausted. Of course, the battery will eventually run out, when you found them on the fast runs down, you need to replace them.
       The preservation of the battery, carrying a lot to attention. Just to buy back the rechargeable batteries generally low or no consumption of electricity, should be in use before recharging. After the battery is full, hot, should be cooled before loading machines. In order to extend the time for filming, filming process should try not to use the LCD viewfinder; reduce the number of optical zoom.
       When in use as far as possible we want to conserve battery usage. The first is to avoid unnecessary use of the zoom operation, if it is to zoom, we recommend you to move the camera position to get the same effect Zoom! Second is to avoid frequent use of photography lights, power consumption is the major photographic lights, if not compelling general recommendations we do not use. Further adjustments in the use of the best image viewfinder, rather than LCD display ibm battery. LCD monitor the energy consumption alarming, so the best use less, because ordinary shooting through the viewfinder can be completed. Of course, not in order to save power it will be blocked, such as shooting at close range LCD display is an indispensable component. Finally, remember that in the non-use of camera time will be closed.
       The battery of cleaning, most people do not pay attention to. In order to avoid the loss of electricity problems, please keep the battery at both ends of the contact point and the internal battery lid clean. If necessary, use soft, clean dry cloth to gently Fushi. Must not use or cleaning of the chemical, such as solubility of the cleaning agents, such as thinner, alcohol or ingredients containing the solvent cleaning your digital camera, batteries, or charger. In addition, the use of charge, the use of soft dry cloth to clean the battery ends of the contact point, as far as point of contact at both ends of the ThinkPad T23 battery to maintain clean, and this can ensure that the batteries can be fully adequate electricity. If the electrodes have a battery of the situation, the need to wipe out, if it is serious or loading of the situation, they should immediately replace the batteries.
       With the correct method of charging the battery great influence, supporting the use of the charger and battery manufacturer, will help extend battery life. The charging time, depending on the used batteries and chargers, and the use of voltage stability and other factors. If this is the first time the use of batteries (or used for months without batteries), we should remember that the rechargeable lithium batteries when several of its provisions to more than one hour charge time around, nickel-hydrogen batteries must be over 14 hours, otherwise the future Battery life will be shorter. After several normally take charge / discharge process, to achieve the best efficiency. And there are remnants of battery power, so as not to repeat charge to ensure that the ThinkPad T30 battery life.
       In the use of lithium batteries should be noted that some time after the battery is placed into the dormant state, at less than normal capacity, thus shortening the time. However, lithium batteries can easily activated, as long as three to five times the normal charge-discharge cycle can be activated battery and a return to normal capacity. Because of the characteristics of its own lithium battery, its decision almost no memory effect. So users of the new lithium batteries in the activation process, does not require special methods and equipment. Not only is this theory from the very beginning using standard method of charging such a "natural activation" is the best way.
       The lithium batteries "activate" the problem, many of the argument is: charging time must be over 12 hours, repeatedly done three times, in order to activate the ThinkPad X60 battery. This "three times before charging to charge more than 12 hours", is obviously from the nickel batteries (such as nickel-cadmium and nickel-metal hydride) inherited from the argument. Therefore, this argument can be said to the start miscommunication. Lithium batteries and nickel-battery charging and discharging of a very big difference, but can tell you that I have access to all the technical information and stressed that the charge would discharge lithium batteries, in particular liquid lithium-ion battery causing great harm . Thus charging the best time and in accordance with the standard method of charging standards, especially not to carry out more than 12 hours of super-long charge.
     In addition, the lithium batteries in the battery charger automatically stopped after the full charge and there is no nickel, Chargers 10 continuous hours of the so-called "trickle" charging. In other words, if your lithium batteries in full, on the white charger is also sufficient. And we can not guarantee that no one PCGA-BP2EA charge and discharge protection circuit will never change the characteristics and quality of foolproof, so you will long battery life at risk hovering on the edge. This is our long opposed Another reason for charging.

I have just read the battery price and the warranty, you are not think that some sensational, was in not using a laptop battery. In fact, according to the correct method to use, the battery can still longevity. Below on and you talk about the use of:

Laptop battery maintenance methods - 1, you want to activate the new battery longevity of notebook batteries, must have a good beginning, it was from the start with the purchase of notebook. New laptop in the first boot with a battery should be 3 percent of the electricity (this is also a common practice of manufacturers. If you buy the first to open the notebook, has a battery that is certainly used by others), and at this time, you Should not use an external power source, the hp battery in the remainder of the exhaustion of power, until the shutdown, and then use an external power supply charge. After returning home, but also to the battery charge after the exhaustion of power, charging time must be over 12 hours, repeatedly done three times, in order to activate the battery, in order for future use and lay a sound foundation.

Laptop battery maintenance methods - 2, to minimize the number of batteries used this method seems to give people some feeling stingy, but it is also the most effective. We should know that the number of battery charging and discharging directly related to life, filling each one, battery on a step forward to retirement. We propose to make full use of an external power supply, use an external F2019B power should be removed. Some friends convenience, often several times a day in the power plug, and notebook computers equipped with batteries, to do so, the greater the damage to the battery. Because each access to an external power supply equivalent to a battery charger, a battery naturally Zheshou.

Laptop battery maintenance methods - 3, after the exhaustion of electricity charge and avoid charging time is too long regardless of your notebook to use lithium or nickel-hydrogen power, electricity consumption to a certain exhaustion after filling (less than 1% of electricity), which is Avoid the memory effect the best way. On lithium not the memory effect, I have been in front of businesses that are irresponsible and misleading. Lithium will be the same memory effect, it is only the memory effect is somewhat smaller than the nickel-hydrogen only. And cell phone F1739A charging the same method as that, when you give laptop batteries, to avoid long time, the general control within 12 hours. As for the Prevention of exposure to prevent exposed to moisture, prevent erosion of chemical liquids, avoid contact with the metal battery of attention to matters such as contacts, will not mention here the

Nokia announced Tuesday, Panasonic-made lithium laptop battery overheating part of the problem, the company will take the initiative to recall these products, and for users to replace the battery, it is learnt that the incident related to the recall of up to 46 million mobile phone. It is not clear the company would recall and replacement of the number of batteries, but the number of recalled Sony batteries is expected to more than four times higher than the incident has become the industry's largest battery recall in the incident.

     Since last August Dell announced the convening of a large-scale production of Sony, used in notebook computers lithium inspiron laptop battery, the battery industry has been plagued by such incidents. Almost all major computer makers have announced a recall Sony laptop batteries, and Sanyo Electric also recalled a phone batteries and notebook batteries.

     Battery Recall the continued occurrence of the incident reflected the one hand, business-to-consumer more prudent and responsible attitude, on the other hand also shows that Inspiron 700m battery production there are still many problems. Rechargeable lithium batteries in the past 15 years has been a notebook computer and mobile phone industries rapid development of one of the important factors, the relatively inexpensive price of lithium batteries, light weight, good environmental performance, is superior to nickel-chromium battery.

     But on the other hand, the current lithium Inspiron 5100 battery have greater, more complex manufacturing process, fever and even more easily overheating, short-circuit occurred when the consequences are more serious. Last year, some Sony laptop battery fire incident has happened. Nokia's Matsushita to recall lithium batteries because of alleged battery in charge when overheated.

The cell phone industry and notebook computer industry's rapid development has exceeded the pace of development of laptop battery technology, product features but also increasingly to improve the battery performance in an increasingly high demand.

     Frequently the lithium battery incident prompted some manufacturers to take a more cautious approach. Toyota Motor has postponed the hybrid vehicles use lithium latitude battery on the plan. Nevertheless, industry experts still believe that, despite limitations of lithium batteries, but in the foreseeable future, it remains the most practical battery technology.

     Sony announced this week, the company will spend 97.6 million U.S. dollars in Singapore to build a mobile phone 1691P manufacturing plant to consolidate its market share. The plant will use more advanced lithium-ion polymer technology, the factory is expected to be operational in August next year, on the initial production capacity will reach 1 million by 2010, will reach 8 million. Toshiba is currently working hard to develop alternative energy technologies, such as fuel cells, batteries not to use such chemicals, but there is still a considerable battery business into a long way to go.

     Matsushita is the world's top four manufacturers of lithium 75UYF, the company said that its battery problems in the manufacturing process. When used to prevent a short circuit occurred insulation damaged, will result in overheating. Nokia said that so far, Panasonic lithium batteries overheating problem caused by only 100 reported, but no serious casualties. Nevertheless, Nokia will continue to take preventive measures to replace all the production date in December 2005 and November 2006 between the origin of similar batteries for Osaka.

     Matsushita is expected to bear most of the costs of replacement 8N544 at an estimated cost of up to 170 million U.S. dollars. Impact of the news yesterday on the Tokyo Stock Exchange, Matsushita shares fell nearly 5 percent, to close at 2,015 yen on.

Single-slope conversion according to a fixed point for charging capacitors, resistors and through the known reference (MCU internal integration by comparison to measure the resistance) to measure the discharge time. System of the unknown resistance to repeat the cycle. Integrated timer can automatically collect discharge time laptop battery, as allowed in the discharge cycle in the process of measuring the closure CPU, automatic acquisition of such power can be saved. Technology to follow the slope of the single-rate principle, can be eliminated with the RC-related charge voltage discharge, charging capacitor and the complex index equation. Measurement of time and discharge resistance proportional to the accuracy of the sensor and reference the same resistance, and can eliminate expensive calibration procedures.

10 K can be a resistance for the external temperature sensor reference resistance and 10 K's thermistor; 20 K for the potential of 6.8 K resistance in series with the potential of set points. Series resistance can be identified with the maximum temperature ibm battery set point (about 95 F) the corresponding minimum resistance. Resistance to set a maximum 26.8 K, corresponding to the minimum temperature set point (about 40 F).

Measuring sequences need to refer to resistance, set point and thermistor potential of the implementation of discharge time measurement. MCU calculated by the set-point potential of the value and thermistor, is a highly efficient form of software routines for the code to minimize the number of cycle and the corresponding effective current ThinkPad R51 battery. Effective measurement sequence takes about 10 ms and the average 50 A current, including the need comparators, timers and CPU functional implementation. Without the need for the system to turn off all the built-in MCU peripherals and components. As every five seconds before the need for a 10 ms measurement series, the effective duty cycle is only 0.2 percent, equivalent to about 1 A system of the average current consumption.

Trigger low-voltage heating / cooling relay the current 10 ms of 100 mA current pulse. According to statistics, the relay may be necessary to trigger 16 times per hour. Therefore, the effective duty cycle for the relay 0.0044 percent, equivalent to about 4.4 A of the current system.

From the battery perspective, we care about is triggered by the need to relay the 100 mA current. The first generation of electronic thermostat initial selection of button-type battery is CR2032 lithium ThinkPad T41 battery. Because less than 1% in each of the inherent ultra-low leakage and extremely flat discharge curve (the two of the extended battery life ideal choice), this battery is rated capacity of 200 mAh. CR2032 impedance of the problem is high, about 20, so it prevents the battery to trigger cooling and heating systems to provide 100 mA current relay. Although the required 100 mA pulse current only lasted 10 ms, but still far beyond the button battery capacity. Designers have considered using large-capacity capacitors (due to cost reasons can only be used electrolytic capacitor), but because of this high capacitance leakage, finally gave up.

In this case will explore the first generation of electronic thermostat on its MCU, but with the need for additional external temperature measurement of integrated circuits, and the MCU to wake up the external oscillator and laptop battery monitor. In addition, the thermostat need expensive artificial calibration. These first-generation solutions need more than 20 A of current, battery life can only reach 2 to 3 years, IC total cost of more than two U.S. dollars. To extend battery life and lower costs, the need for re-design.
For this paper, electronic thermostat, the effective duty cycle is very low, because most of their time in standby mode, the system automatically maintain the function of the implementation of wake-up routine affairs. And the potential of different set point, every few seconds on the thermostat to the temperature measurement time. According to the temperature contrast and system chosen by the mode of operation to open or close the cooling or heating,ibm battery and if the temperature is expected within the scope of, not to do anything. Thermostat re-design of the primary goals is to reduce the standby current. To this end, the choice of an ultra-low-power MCU, while running "smart power" (power-wise) software.

In order to extend ThinkPad R51 battery life, the software configured so that MCU into standby mode, which used by the integration of the 12 kHz ultra-low-power oscillator (VLO) time the internal watchdog timer (WDT). Since the elimination of the commonly used low-power 32 kHz crystal, VLO can save costs. All the other closed systems built-in MCU peripherals, and does not bias the temperature sensors and set-point of potential. In such a normal mode, MCU to consume about 0.6 A of current. WDT about once every six seconds overflow, and will be issued interrupt signals from the MCU standby mode wake-up call.

In the work mode, the ultra-low-power MCU's built-in high-speed digital controlled oscillator (DCO) to 1 MHz frequency of default, the time required for the system ThinkPad T41 battery. MCU measuring the temperature set point with users. In support of the lowest cost and the achievement of high-precision measurement solutions based on integrated MCU in comparison with single-slope ADC.

Recently, I stroll in the Forum at the various mobile phone users and found that many players are friends of the use of cell phones by a wide range of issues, some of which also stirred up a lot of friends of the controversy. In fact, for the use of laptop battery at present the views of many of my friends still remain in the relatively early age, in checking the relevant information and a survey of some specific circumstances, the author sums up some common problems and raise their views I hope we can help.

Mistakes one: to buy a new phone before the battery charge three times to give 12 hours
I believe many of my friends in the purchase of mobile phones will be heard when the Shouhuoxiaojie such a proposal: "The new machine three times before charging each time to charge 12 to 14 hours, but not more than 20 hours, after each charge as long as 2 ~ Three hours will be all. " This sentence is wrong? » A few years ago can be said that this statement is the truth, but now is not the same. 12 hours a charge is nickel-metal hydride batteries and lithium before the charge, of course, if you are using or nickel-metal hydride batteries (for example, some PHS), in accordance with this approach is no problem with charging, but now the focus of discussion is More popular on the market lithium vaio battery. Filling 12 to 14 hours in order to activate lithium batteries, many friends and salespersons are in support of this argument, but it seems now that this only applies to pre-2002 production of lithium batteries, because all manufacturers currently in production of lithium batteries Before the factory has been activated off! So now to buy a new phone simply do not need to use a 12-hour battery charge activation of the practice, as long as in a battery charge after an hour with it. Although the lithium battery factory has been activated, but also need to take charge after four or five times to achieve stability and achieve optimal performance. So the best new battery charging four times as much as possible before the first run out of battery inside, while, and then filling in a one hour later on it.
Since the market is still not standardized, resulting in many mobile phone sales staff of professional qualities have yet to be improved PCGA-BP2Sy, because they do not understand the actual situation on the phenomenon of misleading consumers have happened. On the other hand 12 hours a charge of the method due to the time of the reasons for becoming entrenched in the hearts of everyone, so it is that we go out of one of the most common errors.


Mistakes 2: The phone charger is the more serious the better.
Past production of chargers, there have a very Shen of the transformer, because there is a big iron Gatha, very Shen. Now the number of low-grade machines are such a charger. Apart from the use of heavy transformer, there is also a way to achieve the purpose of AC to DC, but can not transformer, so the quality is very light. It uses a number of other ways to achieve this function, the principle is more complicated, not on the depth. In fact, cell phone charger is not a mysterious thing, it is a small transformer, PCGA-BP2Tis generally used on the Walkman of the kind, but much higher quality. We can see that many new production of chargers are very light, such as "standby Wang" Philips 9 @ 9 + + with the original charger is very light, mobile phone charger is not the more serious the better. Many think the recent news reports on the exposure of some amplifier inside in order to increase the added weight of iron and bricks, so consumers should not be misled by JS that the charger is the more serious the better.

Perhaps this is not really the real significance of the error, but in fact many of my friends is very concerned about the maintenance of the laptop battery, for which the author based on the theory and practice here on a battery of view: cell phones simply do not need Maintenance bother!
Lithium batteries is in accordance with the filling-in terms of life, generally a normal lithium battery can charge and discharge 500, 500, is in extreme stringent requirements under the charge and discharge, including limiting the discharge of the load, the discharge Voltage, current, time, we in the process of the use of mobile phones is absolutely impossible to do so. Here we have to pay attention to this point, more than 500 times does not mean that the batteries can not be used, but that the performance of the vaio battery lost, but can still be used. Then we make such an assumption: an ordinary cell phone (or color camera with the exception), a rechargeable cell phone four days, 365 days a year, the charge is the number 91, according to charging and discharging 500, can be five years And five years later, batteries can also continue to use, but performance has declined.
This is the ideal situation, we consider that we charge and discharge is not strictly in accordance with the detection of PCGA-BP2Sy charging and discharging as constant current constant pressure and holidays frequent use of mobile phones, or from time to time due to an emergency signal a lack of high-power signal launch massive consumption of electricity, then we Can guarantee a battery life of four years no problem.
Then we think, is not too conservative for a young man, a phone will use four years? » Think about four years ago the phone, you are also willing to use it » And now buy mobile phones are generally sent two batteries, that is because we can rotate two batteries, so batteries can also work to further extend the double! So the majority of cases the PCGA-BP2T can be used, but do not have to have a cell phone. Unless, of course, you intend to use mobile phones has been scrapped. But now most people are basically for more than two years to one of the phone. In such circumstances, we also Yongde Zhao bother to maintain the battery? » We could very arbitrary use of batteries, to charge any time on what time charge, there is no need to consider maintenance issues, but also the memory effect of lithium batteries can almost be ignored or not, we need not worry that its performance will drop.

Response to national energy saving, environmental policy call, some manufacturing industries in transition to produce quality environmental protection and energy conservation products, but these products are currently facing the market torture, to promote the situation is not optimistic. The laptop battery industry embarrassment faced by the market is particularly prominent. 1997, the China Light Industry Association, the State Environmental Protection Administration and other departments jointly issued a 9 "restrictions on the amount of battery products containing mercury rule", since the request on January 1, 2001, to prohibit the domestic production of various kinds of mercury in the Battery weight of 0.025 percent in the battery.


     Since January 1, 2005, to prohibit the domestic production of mercury in batteries weight of 0.0001 percent larger than the alkaline zinc-manganese batteries (not mercury content of less than 2 percent of the button alkaline manganese and silver oxide battery). Through policies aimed at "baton", the source take the lead in the production of high standards, thereby boost the market consumption, environmental protection and energy conservation so as to speed up the process of the popularity of the compaq battery. The provisions have now enacted nearly 10 years, however, environmental protection and energy conservation as the mainstream products in the battery - alkaline batteries in our battery products to cover only 20 per cent, not only with developed countries 80 percent to 90 percent of the high popularity A far cry from the rate, from the national "10th Five-Year Plan" 30 percent of the goal there is still great some distance.

     Western developed countries have basically achieved to energy conservation and environmental protection alkaline battery production and consumption of transition, but in China's market, consumers clearly have not rekindled the enthusiasm of alkaline battery consumption. Guide policy in the  Evo N610C battery cell production of energy conservation and environmental protection at the same time, relevant state departments and industry associations are also actively doing business Tuiyou limit inferior work for environmental protection and strive to create a good energy-saving battery consumption environment.

     Since last August, the State Administration of Light Industry Quality Supervision and Testing Center of the battery special detection, South Corfu, 555, and other 11 backbone enterprises of mercury in alkaline manganese battery of mercury-free batteries have been below the limit of mercury content of indicators in full compliance with the provisions of state departments 9 ; China Presario 1200 battery Industry Association will be 11 brand alkaline manganese batteries identified as the first batch of "green alkaline manganese battery products", recommended to the public. However, despite the relevant state departments and enterprises make joint efforts to popularize environmental protection and energy conservation battery or slow the pace. Many of the industry said that in the consumer market is very crux of the problem areas.

     In the eyes of the vast majority of consumers, the battery is only the life of ordinary consumer goods, and soap, toothbrush almost no different. Consumers will not buy batteries and spent too much thought. In addition, alkaline batteries price than ordinary number of high-carbon Presario 2500 battery, many consumers feel that the carbon batteries cheaper benefits, especially in the broader domestic rural market, the level of consumption is still relatively low, so the carbon batteries on the consumer More direct that the consumer is a waste of alkaline batteries. Experts pointed out that this concept is a consumer misunderstanding.

     Consumer sense, energy conservation and environmental protection despite the high price of the battery, but it reflected energy saving, environmental indicators are ordinary carbon battery several times. South of Corfu battery for example, from the electricity index, the South Corfu an alkaline battery power is the same standard carbon battery six times, from environmental indicators, the South almost Corfu alkaline batteries would not cause pollution to the environment , Together with the solid waste disposal; indicators from life expectancy, the ordinary carbon battery life is six months, to maintain the original battery power capacity of 70%, alkaline Presario 700 battery storage period is three years, three years South Corfu battery Electric capacity is also available in 90% from a social sense, alkaline batteries used in the production of more energy saving society. As the non-use of natural manganese ore, manganese dioxide can be used by the use of low-grade manganese carbonate or other Manganese ore processing, so there is no shortage of resources.

     And carbon battery is the main component of natural manganese, but China's manganese ore discharge fewer resources, over-exploitation due to many years, the availability of manganese ore discharge nearly depleted. Experts said that the consumer can have greater repercussions in the battery recycling issue. Whether in the district, school or at institutions, there will be a lot of battery recycling box. Carbon batteries in the general popularity of the times, when people see the recovery of the battery box, will naturally think that the battery is not environmentally friendly things, we should put focus on the box. Such acts of civil recovery to achieve a good result. Energy-saving and environmental protection in the Presario 900 battery will become the mainstream of the times, if we can learn from this thinking, guide the people in the civil awareness of the alkaline battery and consumption, environmental protection will also speed up the process of the popularity of energy-saving battery.

        China Building Materials Association organized and hosted by the "solar cells with embossed glass engineering Jian Dinghui" held in Shenzhen laptop battery. From the nation's building materials industry of nine senior experts of the appraisal committee discussed and adopted the Chinese building materials developed by the International Engineering Co., Ltd. with independent intellectual property rights of the solar cells used embossed glass engineering technology, the identification of the technology to the Highly valued.

      3, to optimize the integrated development of solar cells with embossed glass sets of engineering technology, the first in the Nanbo Group (Dongguan) 250 t / d production line successfully implemented. After nearly two years of production certification, which sets technology can meet the demand for large-scale production, and the smooth operation of production, product quality and stability. Compared with similar foreign technology, with a melting A1078, high efficiency, high yield, low energy consumption, cost and low construction cost and competitive advantage, are entirely independent intellectual property rights, the overall integrated technical Habitat leading domestic and achieve The international advanced level.

       4, the sets of technology in Nanbo Group (Dongguan) 250 t / d, SYP Group (Changshu) 150 t / d, Lutheran Glass Group (Humen) 250 t / d production line, such as the successful application of glass products by the State Quality Supervision, Inspection and Testing Center, Direct sunlight transmission is greater than 91.6% (3 mm), the China glass physico-chemical detection by the Development Centre of detection, iron content of less than 120 ppm, and internationally recognized Swiss SPF Testing Center of the highest levels of solar U1-level certification, and achieve superior Similar foreign products in-kind level of quality. 

     5, which sets the successful development of technology, breaking the monopoly of foreign products in the market, the end of our solar glass all embossed with the situation of dependence on imports. 3.2mm glass by the state of safety glass Supervision F1739A, Inspection and Testing Centre, to the United States (ANSIZ97.1) and Japan (JISR3206) standards, has been authorized users at home and abroad.

       Solar cells is to promote the country make great efforts to promote new energy products, the market demand for rapid growth. The complete sets of technology in the country to promote rapid, substantial export their products to enterprises has brought huge economic benefits, and promote the use of solar energy in China and promote the level of significant, significant social and economic benefits.

      Today, mobile phones in major cities have achieved universal coverage, many people even have two to three cell phones, mobile communications brought in to facilitate the people at the same time, the abandoned laptop battery how to deal with, how to avoid the problem of pollution of the environment also will be Come. We all know that, in order to avoid pollution of the environment, ordinary batteries run out, people will be mostly devoted it to the Recycle Bin, many units, the department will also organize periodic recovery.

      Experts point out that cell phone use lithium batteries run out, if discarded everywhere, not to deal with the case, it caused the pollution will be more serious than fujitsu batteries, will give us the environment, life and physical health hazards.

     In many cities abroad, can be seen everywhere waste electrical and battery recycle bin, to facilitate people to focus on dumping, the Government and major electrical appliances, communications companies will be spent on electrical appliances, abandoned PA3166U-1BRS recycling and processing. I suggest that the relevant departments can also institutions, schools, businesses and public places set up a special phone废电池回收Station, and then reunification of recycling, to reduce urban pollution and protecting people's health, to achieve "Green Olympics" concept to make a positive contribution .

First, to maintain drive, CD-ROM cleaner
     Drive using a very sophisticated optical components and optical components are most afraid of is the dust pollution. Dust from the CD-ROM loaded, to withdraw from the entire process, the cleanliness of the CD-ROM drive directly related to the life expectancy. Therefore, the CD-ROM drive before loading the necessary laptop battery cleansing, the CD should not use the proper custody, to prevent dust pollution.

Second, regular cleaning and maintenance of laser use of the first drive after a period of time, the laser head is bound to infected dust, so that the drive Dupan ability. Dupan for specific performance slowed down, the display screen and a voice of Mosaic or pause, can be a serious drive to hear the voice of frequent read CD-ROM. These phenomena of the laser head and drive motors and other components are damaged. Therefore, users should be cleaned regularly to drive to maintenance or maintenance professionals.

Third, the drive to maintain the level of placing »
Machines used in the course of the drive to maintain the level of place. The reason is that the CD-ROM in the rotation when the focus has changed because of an imbalance, when a slight decline in capacity will enable Dupan, serious damage may be the first laser. Some people use computers in different drive to install software on machines, often used to drive removed taken, or even carry, which drives much damage. The harm is the optical drive components, laser head tilted due to vibration and changes in place, leading to drive performance decline.

Fourth, take time to develop before the shutdown was the habit
Once a CD-ROM drive, not only when the computer started Dupan a very long time, and CD-ROM will also have been on high-speed rotating state. This will increase the laser head of the working hours and also drive the motor and transmission components in a state of wear and tear, virtually shorten the life of the drive. Users to develop recommendations before the shutdown time out from the CD-ROM drive in the habit fujitsu laptop battery.

5, the drive to reduce the working hours in order to reduce the use of drive time, to extend its life, the use of computer users in the hard disk space permitting, can often make use of the virtual CD-ROM disc storage on the hard drive. Such as educational software, games and other software stored on the hard drive, so the future can be run directly on the hard drive, and has the characteristics of speed.

6, less piracy, the use of genuine CDs many friends because of the prices of pirated optical discs and CD-ROM prices have genuine gap, coupled with the purchase of CD-ROM is rich in content and use, based on China's national conditions, this is beyond reproach, but because of your drive long-term Reading For pirated optical discs, because of their poor quality discs, laser head need to repeatedly read data. This increase in the electrical and optical head of the working hours, thus greatly shortening the life of the drive. At present the price of legitimate software VGP-BPL2 has greatly decreased, and some only slightly expensive than pirated software, and a drive Dupan protection. Therefore, we propose the future as little as possible with the use of pirated optical discs of legitimate CDs.

7, correctly set, the Commissioner-box Whatever the drive, the front panel has a clearance boxes and boxes of keys, the regular use of this key is the correct disk drive switch box approach. Button finger can not be excessive force to prevent the keys out of control. Some users have used direct hand was pushed back to box, which drives the transmission gear is a kind of damage, recommends that users overcome this bad habit.

8, using procedures open, Kuan-box
Use procedures set switch boxes, in many software tools or multimedia players have such a function. If using the mouse right-click the Windows CD-ROM drive letter, the pop-up menu also has a "pop-up" order, you can pop CD box. Recommends that computer users to make full use of open software control, customs-box, this could reduce the incidence of drive failure.

9, careful maintenance
Because of all the drive components are very sophisticated users in the installation and opening drive in the process must pay attention to ways and means to pay attention to the fixed location of the original record. If you do not grasp, it may request the professional maintenance personnel entry and maintenance. In particular, the first laser aging, need to be adjusted to improve the power supply of laser power, must be professional maintenance staff to debug, to prevent their adjustment VGP-BPS3 too large, making the first laser burn.

10, as little as possible-video discs
This can be avoided drive to work long hours, due to continuous Dupan long drive to drive great impact on life expectancy. Users will need to be regularly broadcast programmes, or the best of their Kaoru hard to ensure that the drive longevity. If indeed often depends on video discs, proposed to buy a cheap low-speed drive designed to play VCD.

       From the use of terms, digital cameras in the viewfinder, exposure, image processing, storage and playback when the power consumption with different characteristics from the main device to analyze the power consumption of LCD screens, flash, image sensor and processing engine power are Big, and basically all of a sudden-only work in the current needs of the moment, the normally quiescent current very small. This has determined that the power consumption of digital cameras, the need for a sudden large current power supply capacity. From that point of view, the relatively low internal resistance of batteries more suitable for the use of digital cameras, digital cameras can significantly improve the response speed. The average charge from the flash of time, the use of lithium laptop battery ahead of the camera, usually just three seconds, and the use of nickel-hydrogen battery models are often longer than six seconds.
      But in capacity, lithium batteries have no obvious advantage to speak of. The measure we use a lot of the times to 2000 mAh (iMax) nickel-hydrogen batteries, digital cameras and the general capacity of the lithium batteries are often in 1000 mAh around. Shooting data also illustrates this point, Fuji S602, such as "running players" have started to catch up with Canon G3, Sony F717's record. GM and nickel-hydrogen batteries used in digital cameras, can always buy emergency battery, or others at any time using the Charger, thinkpad batteries depletion due to a little embarrassing scenes. Exclusive use of the charger, the charging time is often reduced to less than four hours, catching up lithium batteries. Nickel-metal hydride batteries with plenty of energy and nearly 1,000 charge and discharge it into the present cost-effective life of the best digital camera batteries.
      In addition, the battery voltage is also a matter of concern. Recently adopted by the two batteries on the 5th of digital cameras more and more, this measure in the entry-level products are the basic configuration. Reduce weight and energy consumption is a good thing, but in the same types of hardware platforms, high-voltage power supply can often bring about the shooting and faster processing speed and higher image signal to noise ratio. EOS-1D/1Ds used in the series on the 12 V NP-E3 nickel-metal hydride Pavilion DV1000 battery pack is a good example. Therefore, high-performance digital camera on the use of high-voltage battery pack or a period of time may be an inevitable choice.
     2000 mAh battery times can fully show the nickel-metal hydride batteries low internal resistance, large current discharge characteristics of flash recharge faster, and high-speed Continuous, video clips recorded by no means Tuonidaishui. It also with a nickel-hydrogen battery voltage discharge of a smooth, but quickly fell to the end of the characteristics that once prompted to start LCD battery capacity shortage, the remaining capacity will support only a dozen of the shooting. Its charger for a quick charge and the charge of intelligence.

       Experts said that mobile phone batteries to ensure safety, we should note the following. The purchase of the source from the start, the proposed mobile phone sales through formal channels buy laptop battery, not seeking to buy some cheap and quality can not guarantee that the non-original batteries;

      Do not buy it as much as possible to buy and store some of the phone (fakes, two mobile phones, assembly, etc.), and because the quality of the phone itself can not guarantee that, not to mention the allocation of the safety of the thinkpad batteries;

     In everyday use the phone in the process, not arbitrarily modified cell phones, as far as possible, using original Charger, charging as much as possible not to call, if the rechargeable batteries found in the course of severe fever, swelling and even smoking, and other phenomena, we should immediately stop using;

      Do not Latitude CPi battery on the high-temperature environment, but also to avoid the direct summer sun; Do not use damaged cells, not a long time to call;

     Do not linked to the phone in the front, as far as possible on the bag, use headphones to answer the call.

      Lithium batteries electronics products due to small size, high value, usually by air transport. Taking into account the transportation of laptop battery caught fire during a plane crash triggered the explosion of risk factors, the General Administration of Civil Aviation to air transport companies issued a "lithium batteries air transport norms," expressly provides that "check for compliance testing UN38.3 report or certificate, no Can not be shipped to. " According to aviation regulations require, airlines and airport cargo transport sector to respond to lithium batteries for transport document review, the most important thing is for each type of lithium battery UN38.3 safety inspection report. The report could be a test of the ability of manufacturers to provide batteries, may also be designated by the Civil Aviation third-party testing agencies. If unable to provide the test report, the Civil Aviation will be prohibited from batteries compaq for air transport. At present, Shenzhen Bangkai electronics, BAK Battery, two companies in accordance with the relevant provisions of the first was detected and has been qualified report.

      Testing on UN38.3

      With mobile phones, notebook computers, lithium batteries containing the growing cargo transport, the safe operation of airlines to bring about the hidden dangers also increasing. To ensure air transport safety, and to meet with F4812A on the safe transport of cargo demand, according to IATA airlines are "dangerous goods" rules of the relevant provisions for each type of lithium batteries and lithium batteries, must be tested, Has proved to comply with "the United Nations Transport of Dangerous Goods Manual of Tests and Criteria" Part 3 38.3 (hereinafter referred to UN38.3 test) all the requirements. Norms applicable to this operation, including but not limited to, either alone or together with the transport of equipment is rechargeable lithium battery cell phone batteries, laptop batteries, walkie-talkie batteries, camera batteries, remote control toy F4809A.

    The answer is need to activate the laptop battery, but this is not the user to do. I visited the lithium-ion battery production plants, lithium-ion battery factory in the past to go through the process as follows: lithium-ion battery shell instill into the electrolyte --- ---- sealed, the charge is constant pressure, and then discharge, so a few Cycle, so that the full invasion electrolyte electrode, and fully activated, the capacity to meet the requirement, the activation process - this is at capacity, is to test the battery capacity to select a different performance (capacity) to classify the battery, battery of the hierarchy, To match capacity, such as. This out of lithium-ion battery inspiron laptop battery that users have already been activated at all.

      We all commonly used nickel-cadmium batteries and nickel-hydrogen batteries into the case is activated only after the factory. Some of these cells activated in the process of opening a battery, and activated later sealed, this process has only batteries may have the manufacturer to complete.

      Here there is a problem, that is, the battery factory to the battery factory hands of users, this may sometimes be a very long time, is a short, long, half a year, this time, because the Inspiron 6000 battery electrode materials will be passive, so manufacturers use of the initial proposals The best battery for three to five full-filling process, in order to eliminate the passive electrode material, to maximum capacity.

      Promulgated in 2001 on the three nickel-hydrogen. Nickel-cadmium and lithium-ion batteries in the GB, its initial capacity of the test are clearly stipulates that the batteries can be carried out five deep-deep-filling, when once the required time, the pilot to stop.

      This very good explanation I said this phenomenon.

      So called "second activation" is also possible, first-time users of the "new" Inspiron 700m battery charge as much as possible for several deep-cycle.

      But according to my tests (for lithium-ion battery), the storage period of 1 to 3 months of the lithium-ion batteries, it was deep filling the deep-processing cycle, improve their capacity of almost non-existent

      The primary laptop battery cells will be active substances in a chemical reaction through the oxidation and reduction of direct conversion into electricity output devices. Also known as chemical batteries. As various models of the original battery redox reactions of the poor reversible, electric-End, can not re-use, it is also called a battery. It is usually from the electrode, the negative electrode, electrolyte, and the isolation of a shell, made of various shapes and sizes, easy to use. Widely used in industry and agriculture, defense industry and communications, lighting, medical, and other departments and become a daily in radio, tape recorders, cameras, calculators, electronic forms, toys, hearing aids, and other commonly used electrical power. General by the lifebook battery anode active substances (such as zinc, cadmium, magnesium, lithium, etc.) and cathode active material (such as manganese, mercury, sulphur dioxide, carbon fluoride, etc.) into zinc-manganese batteries, zinc-air battery, silver zinc batteries, zinc Mercury batteries, magnesium manganese batteries, lithium fluoride carbon batteries, lithium-sulfur dioxide batteries. Zinc-manganese F4809A production the most, often divided into the electrolyte zinc chloride and ammonium chloride-type, and its isolation of the paste into a low-battery and Presario R3000 battery. With potassium hydroxide as the electrolyte zinc-manganese batteries, because of its negative (zinc), Construction and other zinc-manganese batteries on the different habits and a separate category, known as the alkaline zinc-manganese batteries, or alkaline manganese batteries, commonly known as alkaline batteries .

      At present, the market for sale on the use of the vast majority of electric bicycles are not the memory effect of lead-acid batteries and how to extend compaq Presario R3000 battery life » Experts note will be introduced to the press: First of all, ground handling charge, to avoid "deep discharge." Cycle of electric vehicles use the day to cultivate the habit of charging the same day, no matter how far the daily cycle will be the best battery in the full complement, and not a rechargeable light, and so on. Secondly, when not in a long time, every month - a charge, to the electric hp F4812A battery in full after the storage, make sure to be in deficit, the state of storage. Charging for use of matching charger. Due to the battery of different formulations and the Chargers do not like the technical requirements, which charger what brand of battery charge can be full, is different, therefore, do not mix charger. To protect the hp F4809A battery, users can use with the filling, but not on the use of pick-up voltage to prevent serious losses electricity, battery power, the power should be shut down cycle. Charging, charging indicator light shows when full power will not immediately stop charging, should Fuchong 2-3 hours.

       Digital cameras and camera different digital cameras on the power needs of particularly great. Therefore, lithium batteries hp F2299A battery hp Pavilion DV1000 battery and nickel-hydrogen batteries these can be reused and also the larger battery power more and more digital camera users welcome. But whether lithium batteries or nickel-hydrogen batteries, all kinds of battery hp Pavilion ZV5000 battery use, retention, attention should be paid to bring in many places. Nickel-metal hydride batteries have memory effect, this effect would reduce the total capacity of the battery and use of time. With the passage of time, storage charge will be less and less, the battery consumption will also have more and more rapidly. Hence, we should all try to run out of electricity to recharge. If you are using the special lithium batteries or lithium-ion batteryhp Pavilion DV4000 battery, memory effect on the problem of how to consider the need.

     In the course of everyday use, it is necessary to pay attention to maintaining the integrity of skin cell insulation, once found damaged, should use transparent tape Nianlao. Check whether a battery electrode of the situation, its mild oxidation can wipe out, but if they are serious or loss of the case, should immediately replace the batteries. At the same time, in order to avoid the loss of electricity, the need to maintain the battery ends of the point of contact within the lid and the battery clean and, if necessary, can use soft, clean dry cloth to gently Fushi batteryhp Presario V2000 battery. With small erasers (such as the kind of a pencil head) Shendao battery pack, clean metal contacts, but must not use cleaning agents with the solubility of cleaning agents.

     In addition, a long time when you do not intend to use digital cameras, must be from a digital camera battery ibm ThinkPad R40 battery charger, or out of, and fully discharged, and then stored in dry, cool environment, but not to normal cells Metal objects placed together, this non-rechargeable batteries are particularly important.

      1. Electrical and battery toshiba PA3166U-1BRS battery contacts should be clean and, if necessary, with wet cloth Cajing, after drying to be marked by polar properly loaded. Please identify with battery toshiba PA3331U-1BRS battery polarity ( "+" and "-") to install extremely important, should be a statement of the electrical installation requirements recommended by the battery; not to request brochures, will lead to equipment failure, damage to electricity equipment and / or Battery. If three or more than three batteries in series, including a loaded anti-polar, reverse battery toshiba Satellite A75 battery charge, internally generated gases, in relief and electrolyte leakage.

     2, Do not mix old and new batteries, but with a different model type or brand of electrochemical cells do not mix, or will a group of batteries toshiba Satellite A70 battery toshiba PA3384U-1BRS batteryin some batteries in use in a state of the discharge, thereby increasing the possibility of leakage.

     3, can not be a one-time renewable heating or battery charging, or else they might explosion occurred.

    4, not short-circuit the battery, so as to avoid a leakage of the battery dell 1691P battery or damage to the heat insulation overpack.

    5, not demolition batteries, not heating the battery.

    6, long-term electrical batteries dell 75UYF battery dell 8N544 batterydo not have to be removed in time, should the power is switched off after use, so as to keep the battery to discharge its internal adverse chemical reaction caused by leakage.

    7, scrap batteries will not arbitrarily discarded, as far as possible with other refuse from running.

      June 16, sources said the Nokia 6280 phone models using original rechargeable batteries dell Inspiron 8000 battery apple M8511 battery and chargers, battery expansion will appear at any time and the risk of explosion, involving battery models for the BP-6M. Nokia Chinese company subsequently issued a statement saying that the Chinese mainland yet received similar complaints and said that if consumers find "Fa Zhang," the original Nokia batteries, battery apple M6091 batteryto provide the original purchase documents, even beyond the warranty period can be replaced. However, the latest in a statement, Nokia will replace the batteries to narrow the scope of the "warranty period", "Three Guarantees will be in the life of the battery to provide a free replacement."

      Nokia reiterated that the current Chinese companies in mainland China have not received similar reflect, consumers have doubts about the batteryapple A1012 battery, to the Nokia authorized service centers for testing. In June 17 after two days, this newspaper received many readers asked, said more than once at the Nokia Service, but the knowledge that customer service, Nokia person explained to reporters that the statement issued to the customer service department takes a certain period of time, CS Has received the notification.
