To discharge (49), the knob (11) of the changeover switch (7) is moved in the direction toward the charging plug receiver (12) to connect the battery groups (1) and (2) in parallel. Then, a relatively low voltage is generated between the positive electrode pin (8) and the negative electrode tube (9) to be used as a power source that can be used for a long time. When charging the batteries (40) to (49), the knob (11) is moved in a direction away from the charging plug receiver (12) to connect the battery groups (1) and (2) in series. Then, the charging plug (14) is inserted into the plug receiver (12) to charge the batteries (40) to (49) with a uniform charging current. However, when the knob (11) is close to the charging plug receiver (12), the knob (11) comes into contact with the stepped portion (16) and prevents further intrusion, so that the positive electrode of the plug receiver (12) is prevented. Pin (8)
Cannot contact the positive terminal (17) of the plug (14). Therefore, the mistake of accidentally charging the battery groups (1) and (2) while they are connected in parallel is eliminated.
