Battery capacity of laptopVirtually all modern laptopscomplete with lithium-ion batteries. Batteries of this type have a number of remarkable consumer qualities: they are light, compact, powerful, have a high capacity and are almost not subject to the "memory effect". But they also have disadvantages.

  1. Lithium-ion cells are sensitive to the temperature of the surrounding air. They can not be used at temperatures below zero - each launch will significantly reduce capacity.

  2. Despite the absence of a "memory effect"The lithium-ion power supply should be regularly "trained", and for this once every 2-3 weeks to make the computer run on battery even under stationary conditions. Do not neglect the procedure for calibrating the battery (available in the BIOS menu). Its meaning is to fully charge and then completely discharge the battery. Therefore, even if the developers did not provide such an option, the calibration can be done manually: charge the battery up to 100% and, having turned off the energy-saving functions, discharge it as quickly as possible to completely turn off the computer, for example, playing a movie with maximum display brightness, simultaneously with defragmentation and copying a large amount of data.

  3. If the laptop is constantly running in stationaryconditions and gets power from the mains, it is advisable to charge the battery and remove it from the computer. It is recommended to store the extracted battery in a sealed plastic bag in the refrigerator (at a temperature above zero). But it must be remembered that the laptop is deprived of its own uninterruptible power supply, whose role is performed by a rechargeable battery.

  4. Regardless of whether the battery is removed from thelaptop or not, its contacts can be oxidized, and even a thin film of oxides can reduce battery life. Therefore, it is strongly recommended to clean the battery contacts at least once every 2-3 months.
