PURPOSE:To provide a battery weight correction unit which adjusts weight difference caused by different types of power source batteries in a battery- powered appliance operated on the water or in the water. CONSTITUTION:A projection 12 having the same dimension as the projection dimension of a positive terminal of a battery is formed at one end of a battery weight correction unit 11 having the same length as a battery main body, and a push spring 13 is fixed to its other end. This type of weight correction unit is mounted in the corner spaces of a battery box 18 in parallel to a battery A so as to adjust weight difference between a light battery and a heavy battery used in a battery-powered appliance operated on the water or in the water. |
