1. Do not charge lithium-ion batteries to 100% full, and never use them up completely.
2. Do not leave lithium-ion batteries (especially laptop lithium-ion batteries) plugged into the device for extended periods. Maintaining 100% charge for extended periods is tantamount to killing the lithium-ion battery.
3. Lithium-ion batteries should generally be stored in a cool place. They should not be frozen or placed in high-temperature environments. The aging rate of lithium-ion batteries is determined by temperature and charging status.
Therefore, when charging lithium-ion batteries, use the original battery charger and charge them using the standard method, i.e., slow charging.
