A battery charger and method for terminating charging at a designated time. After terminating first-stage constant-current charging by a first charging current, the charging is paused for to the designated charging termination time minus a second-stage constant-current charging duration. After the termination of the standby duration, second-stage constant-current charging is started and terminated at the charging termination time. The battery is not excessively charged but warmed up by heat generated by the battery itself at a stage close to the end of charging. When the standby duration is long, the second-stage constant-current charging duration is corrected according to the battery temperature or the temperature of the surrounding atmosphere. The invention can be applied to a charging method other than the two-stage constant-current charging.
