laptop battery http://laptoppopbattery.blogbus.com by blogbus.com Thu, 01 Jan 1970 07:00:00 +0700 http://public.blogbus.com/profile/4/9/6/4465694/avatar_4465694_96.jpg laptop battery http://laptoppopbattery.blogbus.com Phone lithium battery knowledge 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.

]]> http://laptoppopbattery.blogbus.com/logs/30205768.html wangzhihui624 Mon, 13 Oct 2008 17:35:53 +0800 For the first time on the phone and rechargeable lithium battery of knowledge 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.

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!

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.

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.

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!

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.

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

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.

     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.
