myecpro-laptop battery

Choose the charger, it is best to use those with the right to terminate charging device (such as the anti-time-off rechargeable devices, negative differential voltage (-dV) cut off the charge and anti-overheating sensor device) charger to avoid overcharging the battery due to shortened life . Generally speaking, slow charging more than the fast charge to extend battery life.

2) Discharge:

Discharge depth of the impact of ibm laptop battery life are major factors, the higher the depth of discharge, the shorter the battery life. In other words, as long as the lower depth of discharge, we can significantly extend the battery life. Therefore, we should avoid the battery had to put a very low voltage. Generally speaking, if the battery voltage is finally from 0.8 to 1.0 volts, it belong to the acceptable limit, subject to the basis of the size of the discharge current.

If the thinkpad r51 battery  discharge at high temperature will shorten battery life.

If the design of electronic equipment will not completely stop all current, then the equipment a long time if left unused, and not put the battery removed, the residual current can sometimes make too much thinkpad r40 battery consumption, resulting in the battery before discharge.

Different electric capacity, chemical structure, the level of thinkpad r32 battery  charge, as well as mixed the old and new batteries mixed use, the battery will discharge too much, or even result in anti-polar charge.

3) Storage:

Cell prolonged high temperature storage, it will become the electrode degradation, shortening the service life.

Avoid prolonged put the thinkpad a20 battery  on the charger inside.
