Abstract

PURPOSE:To easily display a battery residual capacitor at the time of incorporating a secondary battery pack in a camera main body and to singly check a battery as necessary. CONSTITUTION:The battery pack 1 attachably/detachably loaded in a camera is constituted of a secondary battery capable of being repeatedly used, a means calculating charge and discharge quantities for the battery and a means 12 displaying the residual capacitor of the secondary battery obtained by the means, the battery residual capacity display means in the secondary battery pack can be visually recognized ay a notched part 20 provided on the rear surface side of the camera main body 2 from the outside at the time of loading in the camera and a means actuating a display means in accordance with a connecting operation to the camera and a discharger is provided in the secondary battery pack.
