Lithium-ion batteries can be recharged 300 to 500 times. It is best to conduct partial discharge rather than complete discharge of lithium batteries, and to avoid frequent full discharge. Once the battery is off the production line, the clock starts to move. Whether you use it or not, lithium-ion batteries only last for the first few years. The decrease in battery capacity is due to increased internal resistance due to oxidation (which is the main reason for the decrease in battery capacity). Finally, the resistance of the cell reaches a point when the battery is fully charged but the battery cannot release the stored power.
