ABSTRACT:
A battery discharge indicator device for use on battery powered mining haulage vehicles is provided which automatically monitors the discharge condition of each of the battery supply sources provided on a mining haulage vehicle. The battery discharge indicator provides a continuously flashing lamp indication when any of the battery supply sources discharges to a predetermined level required to power the mining haulage vehicle to a charging station. A momentary flashing indication is further provided when the discharged battery source or sources are replaced with charged battery sources thereby indicating to the operator that the battery powered mining vehicle is ready for use.
