Almost all modern laptops are equipped with lithium-ion batteries.Batteries of this type have a number of excellent consumer qualities: they are lightweight, compact, powerful, have a high capacity and almost never subject to "memory effect".But there are also disadvantages.
- Li-ion cells are sensitive to ambient temperature.They can not be used at temperatures below zero - each launch will greatly reduce capacitance.
- Although there is no "memory effect", a lithium-ion power supply must be regularly "exercise", and this time 2-3 weeks make a computer run on battery power, even in a hospital.Do not neglect the battery calibration procedure (see the menu BIOS).Its meaning is fully charged and then completely discharged battery.Therefore, even if the developers did not foresee such an option, it is possible to produce a calibration manually charge the battery to 100%, and turning off the power saving features, as quickly as possible to defuse it to disconnect your computer running, for example, while playing a movie with the maximum brightness of the display, and at the same time defragmentationcopying large amounts of data.
- If the laptop is constantly working in a hospital and is receiving power from the power supply, it is advisable to charge the battery and remove it from the computer.Store the removed battery recommended sealed plastic bag in the refrigerator (at a temperature above zero).But it must be remembered that the laptop loses its own uninterruptible power supply, which performs the role battery.
- Whether the battery is removed from the laptop or not, it can be oxidized contacts, and even thin oxide film can reduce battery life.It is strongly recommended at least once every 2-3 months to clean the battery contacts.
