Life expectancy and its influencing factors

Lithium-ion batteries to charge and discharge 300-500. Best lithium battery partially discharged, rather than fully discharged, and try to avoid frequent full discharges. Once the production line is under the battery, the clock began to move. Regardless of whether you use lithium-battery life is only in the first few years. Decline is caused by oxidation of the battery's internal resistance increases (this is the main reason resulting in decreased battery capacity). Finally, the cell resistance will reach a certain point, even the battery is fully charged, but the batteries cannot release the stored energy.

The aging speed of lithium batteries is determined by temperature and charging status. The following table shows the battery capacity is reduced in two parameters.
