What are the implications of overcharging?
Overcharging is another form of abuse which can have a serious effect on battery life, its effects are not as immediately obvious as those of undercharging. It is, therefore, important to check battery voltage and charge current from the charger’s ammeter, and compare it with the recommended rate. Overcharging due to excessively high charging rates or charging for too long a period produces excess gassing, high temperatures and corrosion of the positive spine. These all result in shedding of active materials and greater water loss.
