How to extend the life of lithium-based batteries

 The life of lithium-ion batteries is affected by environmental conditions (rather than cycling alone). The worst case is to keep a fully charged battery at a high temperature. The battery pack will not disappear suddenly, but as the capacity decreases, the running time will gradually shorten.


Lower charging voltage can extend battery life, which can be used by both electric cars and satellites. Similar regulations can also be made for consumer devices, but these regulations are rarely provided. The obsolescence in the plan will solve this problem.

When connected to the AC grid, the battery life of the laptop can be extended by lowering the charging voltage. In order to make this feature easy to use, the device should have a "long-life" mode, which can keep the battery at 4.05V/cell and provide about 80% of the SoC. One hour before the trip, the user requested the "full capacity" mode to charge up to 4.20V/cell.

Ask the question: "Should I disconnect my laptop from the grid when I'm not using it?" Under normal circumstances, this is not necessary because charging will stop when the lithium-ion battery is fully charged. The topping fee is only applied when the battery voltage drops to a certain level. Most users will not disconnect the AC power, so this practice is safe.

Modern laptops run cooler than older laptops, and reported fewer fires. When operating electrical equipment with air cooling on the bed or pillow, always keep the airflow unobstructed. A cool laptop can extend battery life and protect internal components. Most consumer products have energy batteries that should be charged at a temperature of 1C or lower. Avoid using so-called ultra-fast chargers, which claim to be able to fully charge lithium-ion batteries in less than an hour.
