Battery Charging Stages & Battery Charging Procedure
Batteries have four main charging stages: pre-charging, constant current, constant voltage, and topping off. Pre-charging is the stage where the battery charger supplies a low current to the battery to help reduce sulfation. Constant current is the stage where the charger supplies a constant amount of current to charge the battery.
