ABSTRACT:
A battery charger includes a circuit for detecting battery voltage (V1) appeared when a predetermined time (T1) has elapsed after starting a charging operation. The determination as to whether the battery has been fully charged is performed after the battery voltage has reached the sum of a predetermined potential difference (dVS) and the battery voltage (V1).
