What happens when a battery overcharges?
During overcharging, the battery’s voltage capacity steadily rises and surpasses the safety ceiling, commonly known as max voltage. When this happens frequently, the cell unit eventually loses its capacity to keep a charge and becomes dysfunctional. The more time a battery spends on the charger after reaching full capacity, the higher the chances of a negative chemical reaction being provoked inside the cell. Basically, its internal resistance capacity will slowly build up and once it reaches a critical level with time, the lithium-cell is rendered useless.
