Abstract
A battery charger includes a battery voltage detecting circuit for detecting a voltage of a battery during a charging operation. The battery voltage detecting circuit includes a pair of a first and a second voltage-dividing resistor. A transistor is interposed between the first and second voltage-dividing resistors. A predetermined voltage is applied to the base of the transistor, so that the battery voltage is detected based on the voltage divided by the first and second voltage-dividing resistors.
