A sealed lead-acid cell is provided with an internal cell restraint (36) which contacts the interior surface of the cell cover (14) and is positioned between the positive plates of the cell and the cover (14), the internal cell restraint (36) cooperating with an external cell restraint (50), such as a plastics coated metal face plate, to direct positive plate growth which occurs in service away from the cover (14). The cell construction disclosed allows plastic-to-plastic seals to be used between the terminal ports (18, 20) and the cover (14), and allows cells of capacities of up to 2,000 Ampere Hours or more to be provided. <IMAGE> |
