One of the charge methods which has current limitation. According to the charge time, some fixed amount of capacity is charged. Therefore this charge method requires some devices which prevent overcharge such as timer etc., for VRLA battery.
Constant current charging involves charging with a constant charging current and variable charging voltage. This process is normally used for Nickel-Cadmium and Nickel-Metal Hydride cells or batteries.
A charge during which the current is maintained at a steady state value.
