Influence factor for rechargeable li ion battery: overheating or undercooling environment
Temperature also has a significant impact on lithium battery life. An environment below freezing point can cause a lithium battery to burn down as soon as the electronics are turned on, while an overheated environment in replacement rechargeable batteries can shrink the battery's capacity. Therefore, if the laptop is used for a long time with external power supply and does not remove the battery, the battery will be in the high heat discharged from the laptop for a long time and will be discarded soon
