PURPOSE:To obtain a sealed lead-acid battery having good and stabilized capacity by installing holes on the side of a container and inserting projections into the holes and pressing an electrode plate group by the projections. CONSTITUTION:In a sealed lead-acid battery in which electrolyte is held in positive and negative plates and separators, and free electrolyte is removed, threads are cut in a hole 2 installed on the side of a container and a projection. By screwing the projection, an electrode plate group is pressed. In the battery in which electrolyte is not yet poured, the container 1 and the projection 3 can be fixed and sealed by adhesion with the plate group pressed by the projection 3. In a large scale battery which is difficult to assemble with pressure applied to a plate group, the plate group can be easily pressed from the side of the battery after assembling. |
