A spill and leak containment system for a liquid electrolyte battery such as a zinc-bromine battery. The system includes one-piece, electrolyte reservoirs with pump mountings and other openings positioned at or near the tops of each reservoir. Positioning the openings at the tops of the reservoirs reduces the amount of electrolyte that might spill out of them, in the event of a leak or breach in the seal between the opening and the component mounted therein. The pump openings are surrounded by sumps, which will catch and contain liquid if there is a leak. To help contain vapor leaks, the invention also includes a vapor recovery system coupled to reservoir when it is filled with or emptied of electrolyte. The vapor recovery system allows for an exchange of vapors to occur between an electrolyte container and the battery reservoir while electrolyte fluid is being transferred. This prevents electrolyte vapor from escaping into the atmosphere where it might be potentially harmful to personnel setting up the system. A pressure equalization system is also provided in order to equalize the pressure between the anolyte and catholyte reservoirs.
