ABSTRACT:
In a battery charger for use in charging a secondary battery, a display unit displays a necessary charging time which is left until completion of charging operation. The battery charger adopts a constant-voltage and constant current control method. A memory memorizes charging voltage and charging current characteristics of the secondary battery. A voltage detecting circuit detects a charging voltage of the secondary battery and produces a detected voltage signal. A current detecting circuit detects a charging current of the secondary battery and produces a detected current signal. A control circuit decides the necessary charging time on the basis of the charging voltage and charging current characteristics, the detected voltage signal, and the detected current signal. The necessary charging time is displayed on the display unit in the form of numerals and the like.
