PROBLEM TO BE SOLVED: To provide a connecting cable for battery pack which makes it possible to grasp the remaining quantity of a battery pack with accuracy even if equipment is used in a place away from the battery pack. SOLUTION: The connecting cable for battery pack is provided with a remaining battery quantity indicating unit. The indicating unit indicates the remaining quantity of a rechargeable battery based on the detection voltage of a detection circuit for detecting voltages or currents of batteries housed in a battery pack, or based on the outcome of the detection voltage. The connecting cable for battery pack is provided with a display switch for causing the remaining battery quantity indicating unit to make a display. Thus, an equipment user can check the remaining quantity only when needed, and power consumption is reduced. COPYRIGHT: (C)2003,JPO
