2 Lithium batteries are not like nickel batteries. They can be fully charged, N9 If the battery is fully charged and charged for a long time, the battery will be discharged. Generally, it will be fully charged after 2.5~3.0 hours of charging. Lithium batteries need to be well maintained. As 1L said, don't use them all before recharging them. I usually charge them when there is about 10 left.
