いという問題点があった。Problems to be Solved by the Invention However, in the conventional sealed lead-acid battery structure described above, when a plurality of sealed lead-acid batteries are assembled into an outer case, the steps of depressurizing, taping, measuring group thickness, and layering cushioning materials are required. This requires time and effort, and also causes problems such as displacement of the cushioning material, resulting in defects.Furthermore, since the exterior body that surrounds each sealed lead-acid battery is only made of thermoplastic resin film, it is difficult to assemble the battery. The problem was that the inside was easily damaged from the outside.
