Batteries to be charged include single, single, and single types that differ in size, shape, and capacity.
Chargers have been proposed that charge these batteries of different sizes with appropriate charging currents. That is, in order to charge three types of batteries, the conventional charger has a battery storage recess on one opposing inner wall of the charger.
A common positive (or negative) contact piece is provided, and three types of negative (or positive) contact pieces with different current limiting impedance elements connected in series are provided on the other opposing inner wall. Therefore, in a charger in which the three types of batteries are selectively stored in the battery housing recess, there is a drawback that the number of contact pieces on the other opposing inner wall side is large and the battery is bulky.
