Lithium batteries can generally be charged and discharged 300-500 times. It is best to partially discharge the lithium battery instead of completely discharging it, and to avoid frequent complete discharge as much as possible. Once the battery is removed from the production line, the clock starts to move. Whether you use it or not, the lifespan of lithium batteries is only in the first few years. The decrease in battery capacity is due to an increase in internal resistance caused by oxidation (which is the main reason for the decrease in battery capacity). Finally, the resistance of the electrolytic cell will reach a certain point, even though the battery is fully charged at this time, it cannot release the stored electricity.

　　The aging rate of lithium batteries is determined by temperature and charging state. The following table illustrates the reduction in battery capacity under two parameters.

　　Temperature charging 40% Charging 100%

　　98% capacity after one year at 0 ° C 94% capacity after one year

　　25 ° C, 96% capacity after one year, 80% capacity after one year

　　40 ° C 85% capacity after one year 65% capacity after one year

　　60 ° C, 75% capacity after one year, 60% capacity after three months
