FIG. 1 shows a state in which a dry battery 1A as a charging power source is attached to a power source section 1 provided on the back surface of a charger with a predetermined polarity. 2 and 3 show a charging section 2 provided on the left side and a storage section 3 provided on the right side of the surface of the charger, which serves as a battery to be charged attached to a holder 4 during charging. A thin rechargeable battery 5, preferably a button-type nickel-cadmium rechargeable battery whose voltage per unit cell is lower than that of the dry battery 1A, is attached to the charging section 2 as shown in FIG. The thin storage battery 5 that has been charged is moved from the charging unit 2 to the storage unit 3 as a spare battery as shown in FIG. The charging unit 2 and the storage unit 3 are semi-circular recesses, and the recesses of the charging unit 2 are provided with contacts of one polarity on both inner sides and contacts of the other polarity on the inner bottom. There is. Further, the holder 4 is provided with contacts corresponding to the charging unit 2 so as to come into contact with the respective poles of the thin storage battery 5 to be attached.
