ABSTRACT:
A method is used for testing residual capacity and residual discharge time of a battery. The discharge of the battery is first undertaken for period lasting five minutes before the values of the terminal voltage and the discharge current are measured. The discharge rate is then obtained by using an inverse proportion relationship between the terminal voltage and the discharge rate. The residual capacity of the battery is obtained by multiplying the discharge rate by the discharge current. The residual discharge time of the battery is obtained by dividing the residual capacity by a normally-required current.
