Charging with the correct method has a great impact on the battery, and using the original charger and battery will help to prolong the battery life. Regarding the charging time, it depends on the charger and battery used, and whether the voltage used is stable. If the battery is used for the first time (or not used for several months), the charging time of the lithium-ion battery must be more than 6 hours, and the charging time of the Ni-MH battery must be more than 14 hours, otherwise the battery life will be shorter in the future. Generally, it takes several charging and discharging processes to achieve the best efficiency. And the battery still has remaining power, try not to recharge it repeatedly to ensure battery life.
