1. Lithium ion cells are sensitive to ambient temperature. They cannot be used at temperatures below zero — every run will significantly reduce capacity.
  2. Despite the absence of "memory effect", lithium-ion power source you need to regularly "train", and this once every 2-3 weeks to make a computer run from battery, even in stationary conditions. Do not neglect the procedure of calibration of the battery (available in BIOS menu). Its meaning is fully charged and the subsequent full discharge of the battery. Therefore, even if the developers have not provided this option, the calibration could produce manually charge the battery to 100% and disabling power-saving function, quickly discharging it to completely turn off the computer by running, for example, movie playback with maximum display brightness, together with the defragmentation, and copying large amounts of data.
  3. If the laptop is constantly running in stationary conditions and receives power from the power supply, it is advisable to charge the battery and remove it from the computer. Store the removed battery is recommended in a sealed plastic bag in the refrigerator (at temperatures above zero). But you need to remember that the laptop is deprived of its own uninterruptible power supply, which performs the role of the battery.
  4. Regardless of whether you pull the battery out of the laptop or not, its contacts can oxidize, but even a thin film of oxide can reduce the battery life. Therefore, it is highly recommended not less than once every 2-3 months to clean the battery contacts.
