Plural batteries installed in an information handling system are simultaneously charged in a constant current mode to a predetermined charge and then in a constant voltage mode to a full charge to provide a reduced charge time and improved battery life. A current regulator integrated in a battery casing monitors current applied at the battery to maintain constant voltage charging. Voltage to ground of the other batteries is monitored to adjust current at those batteries where voltages in all of the battery cells are maintained substantially equal during charging.
