Zusammenfassung:	PURPOSE:To provide a battery indicator in which the vibration of an indicating meter is suppressed at the time of traveling while enhancing the response. CONSTITUTION:A circuit 4 for indicating the residual capacity of a battery group 3 through an indicating meter 2 is provided with a capacitor C1 for memory connected between the intermediate potential part of the battery group 3 and a negative electrode and charged constantly in order to drive transistors T1, T2, and a capacitor C2 for absorbing voltage fluctuation connected between the positive and negative electrodes of the battery group 3 and feeding charges to the indicating circuit 4 depending on the voltage fluctuation.
