A method of determining the end of discharge voltage, EDV 2 and EDV 0 of a battery according to loading current therefrom and the environmental temperature is disclosed. The methods comprises following steps: firstly, charging the battery until it is full and then discharging at a constant current and a first temperature; then plotting the first discharging curve. The battery is then recharged and discharged as above but at a second temperature. And then a second discharging curve is plotted. After that two sets of EDV 2 and EDV 0 are found from the first and second discharging curve. The resulted known values are then substituted into two empirical equations which are two variables (one variable is discharging current and the other is a temperature dependent variable) empirical equations. Thereafter two equations can be used to obtain the EDV 2 and EDV 0 for any given temperature and discharge current.
