Factors affecting lithium batteries

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.
