Overcharge protected chargers

 

— a function that prevents overcharging is the accumulation of an excess amount of energy by the battery installed in the charger. Overcharging is highly undesirable for any type of battery, and can lead to a variety of unpleasant consequences — from poor performance to overheating and fire. To avoid this, chargers may be provided with automatic devices that monitor the level of charge and automatically turn off the battery upon completion of the process.
