ABSTRACT:
A method for charging a secondary battery with a constant current, in which a peak of output voltage is detected by utilizing a predetermined current value, and then the battery continues to be charged with a current value lower than the predetermined current value, so that the peak of output voltage or a voltage drop subsequent to the peak is detected, or alternatively a timer may be used, for termination of the charging operation.
