ABSTRACT:
A method of detecting the full-condition of a secondary battery of the present invention integrates the amount of charge current with a microcomputer in an environment of the kind causing a charge current to vary. When the charge current falls, the method interrupts a charging operation until an adequate charge current flows. A charging device for practicing the above method is also disclosed.
