Laptop battery frequently encountered problems

Q: How to preserve the battery if I don’t use for a long-term?

A: Charge or discharge to about 50%, and then placed in dry, temperature of 15 to 25 degrees Celsius to preservation, either the temperature is too high and too low are easy to accelerate cell aging.

Q: Is that ok if Laptop battery is not removed when using the power supply?

A: It does not matter, the laptop battery has a protection circuit, it will not continue to charge when full.

Q: My battery is now run only a very short time, how should I do?

A: If you’ve been in the frequent use of the battery, then it belongs to cell aging, which can not be avoided, you can only consider to change a new IBM ThinkPad R32 battery or replace batteries; If you did not use battery a long-term, may also lead to this phenomenon, this time need to completely discharge (until fail to boot up) and then full recharge, repeated several times to activate the battery.

Q: Could I use other laptop’s power adapter?

A: No, there are three obstacles, the first is the notebook computer manufacturers use various different voltage, such as IBM are 16V, COMPAQ mostly 18.5V, SONY part of the model is 19.5V, they are inconsistent. The second is different laptops need different current, from 2A to 5.4A, a small machine needs small current. The third is the various manufacturers notebook power adapter interfaces are different, it is difficult to general use. Therefore, at present there hasn’t a common power adapter to all notebooks. 

Q: How to charge the new machine? How do I maintain the battery?

A: Lithium Dell Inspiron E1705 battery need to maintain a certain electromotive force to maintain its internal chemical activity. Therefore, you need to achieve full charge and discharge, in general, the first three times can be a period of about six hours of charge time, charge electric to 100% if there is no time. To avoid point charge, charge timely when less than 10%, and not to be exhausted, that would be bad to the battery; also try not to charge when higher than 60%. Battery don’t use for a long time should applied to about 50% of electricity and preserve at room temperature and dry environment.

Q: For the first use of the battery, should I charge 12 hours the former three times?

A: This is completely unnecessary, because the current notebook computers have improved power management circuitry and charging management system, when the hp Pavilion dv6000 battery reached saturation, the control circuit will automatically switch to the circuit state, so even if charge a long time is also to no avail.

Q: In order to prevent memory effect, we should run out before charge?

A: Discharge the battery is not only unnecessary before every charge, but also harmful. Practice has proved that the depth discharge of the battery will shorten the life, it is recommended to charge the battery when about 10%. When the sony VGP-BPS2A battery power is still more than 30%, you’d better not to charge, because the memory effect more or less does indeed exist.
