PROBLEM TO BE SOLVED: To provide a charging device capable of easily and surely discriminating the kind of batteries without largely changing its shape. SOLUTION: A discriminating circuit 22 of the charging device 20 discriminates the kind of the battery 2 loaded in a housing part 21 from the state of conduction of a SW1 and a SW2. In the state that the SW1 and the SW2 are switched on, it is judged that the loaded battery 2 is a primary battery 2a, and any charging and compulsorily discharging for preventing a memory effect are not performed. In the case that the SW1 is switched off and the SW2 is switched on, it is judged that the loaded battery 2 is a nickel-cadmium battery 2b. In the case that the SW1 is switched on and the SW2 is switched off, it is judged that the loaded battery 2 is a nickel-hydrogen battery 2c. In the case that the battery is the nickel-cadmium battery or the nickel-hydrogen battery, a charging is started after compulsorily discharging the battery. COPYRIGHT: (C)2005,JPO&NCIPI
