How to calculate the charge time for lithium battery?
The charging time of lithium battery is related to the capacity and charging current of lithium battery.
The formula is as follows: charging time t= battery charge c/ charging current I
Therefore, assuming that the battery capacity is 2000MAH, the charging current is 800MAH, and the charging time of
chargers is 2000/800=2.5 hours. But in practice, the charging time is longer than the theoretical time, because there is
energy loss in charging. The charging efficiency can be improved by increasing the charging voltage.
