ABSTRACT:
A battery watering (8) system using a plurality of cells (14) and modules (12). Watering ramps (11) communicate water from a reservoir (18) to a series of interconnected watering caps (16). A reversible pump (30) is positioned below the watering caps (16) such that water within the watering caps (16) and interconnecting conduits (26, 28) drains through the pump (30) and into the reservoir (18) by syphon when no voltage is applied to the pump (30). A controller (39) automatically operates the watering system (8) by sensing the amp hours used since the last watering and determines whether or not the battery needs water. Successful battery watering or system failure are signaled (40) to the operator.
