PROBLEM TO BE SOLVED: To provide apparatus of displaying residual quantity of battery that correctly displays residual quantity of battery and real residual quantity of battery. SOLUTION: An apparatus for displaying residual quantity of battery comprises calculating circuit 2 for detecting residual quantity of battery 1, a temperature sensor 11 for detecting temperature of the battery 1, and a display 8 for displaying residual quantity calculated from the calculating circuit 2. The display 8 displays the residual quantity and the temperature of battery 1 in two-dimension. The display 8 displays the residual quantity in vertical axis, the temperature in horizontal axis, and real residual quantity in square.
