Abstract
A battery charger has a battery capacity detector for detecting the remaining battery capacity and a timer setter for controlling the timer setting that determines the battery charging time based on the results from the battery capacity detector. The battery capacity detector measures the battery voltage, the battery constant current charging time, or the battery capacity. The timer includes a protection timer to forcibly end battery charging and a constant current charging timer to establish the constant current charging interval.
