Abstract
A device is provided for monitoring the total current discharged from a battery. The device includes a bridge circuit of resistors in which one of the resistors has a resistance which varies according to the current which has passed through it. Whenever the battery passes a current to a load, a small portion of the current is passed through the bridge circuit.
