Abstract

PURPOSE: To make a battery charger available for charging and discharging a battery up to the specified number of times set up to the battery by discharging the battery by means of a discharging circuit before the battery is charged, and by charging the battery in completely discharged condition.
CONSTITUTION: A discharging circuit 10 is provided which completely discharges charged electric charge carriers of a nickel-cadmium battery 5 to be charged so that the battery 5 can be completely discharged before it is charged, while a reference voltage generation circuit 8 as a voltage circuit for comparison to manage final charging and discharging voltage of the battery 5 and a voltage discrimination circuit 7 to compare the voltage between in this reference voltage generation circuit 8 and in the battery 5 are provided. By switching a charging and discharging device 13 through a control circuit 11 based on the output of this voltage discrimination circuit 7, complete charging is to be performed up to the specified capacity.
