A battery charging system which charges a battery in an electric appliance. The battery charging system includes circuitry to supply a charging current from a power supply circuit to the battery which is connected to a load appliance. Also included is a voltage detecting circuit which detects the battery terminal voltage to determine the completion of charging. When the load appliance is operated causing a change in the consumption of electric current, the control circuit suspends operation of the voltage detection circuit. As a result, the change of terminal voltage caused by the change of current consumption is not detected, and erroneous "full-charge" detection is prevented.
