摘要：
A storage battery cell (38) having a positive electrode (20) and a negative electrode (22) which are immersed in a liquid electrolyte (14). The negative electrode (22) is partially exposed to a gas space (18) within the battery cell housing (12). A pressure relief valve (34) allows excess gas to escape the battery cell (38) while preventing air from outside the cell from entering the oxygen in the gas space (18). Exposing a section of the negative plate (22) to oxygen in the gas space (18) reduces water consumption of the cell (38) and extends the maintenance-free life of the battery.
