ABSTRACT:
In a battery charging method and apparatus, a plurality of voltage-division resistors serving as a battery voltage detecting means are connected between the battery and a microcomputer so that a voltage-division ratio can be automatically selected corresponding to the detected battery voltage. Thus, the detected battery voltage applied to the microcomputer is kept substantially constant irrespective of the value of the battery voltage.
