For use with a valve regulated lead acid (VRLA) battery, a fluid fill system and a method of maintaining fill fluid in a VRLA battery. In one embodiment, the system includes: (1) a fluid determination circuit, associated with the battery, that determines a quantity of fill fluid in the VRLA battery and (2) a controller, coupled to the fluid determination circuit, that introduces replacement fill fluid into the VRLA battery based on the quantity to replace fill fluid lost from the VRLA battery. The fluid determination circuit comprises sensors that measure a temperature and pressure associated with the VRLA battery, and a state of a fluid release valve on the battery.
