PURPOSE:To provide a sealed lead-acid battery excellent discharging performance at a low with manufacturing cost. CONSTITUTION:A sealed lead-acid battery has a positive plate, a negative plate, an interpole holding member for holding a space between both the positive and the negative poles, and an inorganic powder body such as grain-shape silica for impregnating the electrolyte. The interpole holding member is made of fiber mat-shape or sponge-shape porous body, which has continuous cavities, having a hole diameter larger than 110% of the mean grain diameter of the inorganic powder body, and the inorganic powder body is filled in the blank holes of the interpole holding body and the surrounding of the plate group. |
