What actually happens when lithium batteries are over-charged …
In order to operate lithium-batteries safely and optimize their life span, they should not be over-charged or deep discharged. What happens when a battery is over-charged? If neither the charger nor the protection circuit stops the charging process, then more and more energy enters the cell.
Lithium Ion Battery
Do not overcharge (greater than 4.2V for most batteries) or over-discharge (below 3V) batteries. Make sure that batteries do not exceed manufacturers'' recommended operating temperatures during charging or discharging. Use caution if charging a battery that is still warm from usage, or using a battery that is still warm from charging.
