PURPOSE:To stably provide a sealed type lead acid battery excellent in the battery performance and the lifetime performance. CONSTITUTION:The gap between a positive electrode plate 2 and a negative electrode plate 3 and the area around the electrode group are filled with powder 5 having a high acid resistance, high resistance against oxidation, a high porosity, and large specific surface area, and the powder and the electrode group are impregnated with a sulphuric electrolytic solution in an amount requisite and sufficient for charge and diacharge of the battery, and so the solution is retained thereby substantially. Therein the filling density of the powder is made between 0.20-0.30g/cm<3>. |
