PURPOSE: A method for measuring a battery residual value of a zinc-air fuel battery is provided to display a measured battery residual value by measuring the battery residual value of the zinc-air fuel battery. CONSTITUTION: An OCV(Open Circuit Voltage) and the temperature of a zinc-air fuel battery are measured. An SOC(State Of Charge) is sequentially predicted(S10). A charging/discharging voltage(Vb), an I/O(Input/Output) current(Ib), and a battery temperature(Tb) of the zinc-air fuel battery are measured by using a voltage sensor, a current sensor, and a temperature sensor. A calculated battery residual value is stored in a memory through a microcomputer(S20,S30). The SOC of the zinc-air fuel battery is corrected through a current model and a stored voltage of an existing fuel battery(S40).
