Accumulators of this type have a number of remarkable consumer qualities: they easy, compact, powerful, possess high capacity and are almost not subject to "effect of memory". But is at them and shortcomings.
Lities-ion elements are sensitive to air temperature. They cannot be used at a temperature below zero — each start considerably will reduce capacity.
Despite the absence of "effect of memory", lities - the ion power supply it is necessary "to train" regularly, and for this purpose time in 2-3 weeks to force the computer to work from the battery even in stationary conditions. You should not neglect procedure of calibration of the battery (it is available in the BIOS menu). Its sense consists in full charging and the subsequent full discharge of the battery. Therefore even if developers did not provide such option, calibration can quite be made manually: to charge the battery to 100% and, having disconnected energy saving functions, as fast as possible to discharge it to a computer blackout, having started, for example, reproduction of the movie with the maximum brightness of the display, along with defragmentation and copying of large volume of data.
If the laptop constantly works in stationary conditions and receives power supply from the power supply network, it is expedient to charge the battery and to take it from the computer. It is recommended to store the taken battery in a tight plastic bag in the refrigerator (at a temperature over zero). But thus it is necessary to remember that the laptop loses own uninterruptible power supply which role is carried out by the battery.
Irrespective of, the battery from the laptop is taken or not, its contacts can be oxidized, and even the thin film of oxides is capable to lower time of autonomous work. Therefore it is recommended strongly at least once in 2-3 months to clean contacts of the battery.
