PURPOSE:To provide a sealed lead acid battery which has a long lifetime and is free from water reduction through a battery jar wall parallel with electrode plates even through a long period of service. CONSTITUTION:A sealed lead acid battery has battery jars 5, 10 and an electrode bunch 1 which is formed by stacking positive electrode plate 2 and negative electrode plates 3 with separators 4 interposed, wherein the negative electrode plates 3 are located at the two ends. Anti-acid metal foils 7, 12 are attached fast to the inside surfaces 6, 11 of the battery jar side walls 4, 14 which are parallel with the negative electrode plates 3. The metal foils 7, 12 are in contact with negative electrode plates 3. |
