The results of the SAE life test and the presence or absence of cracks in the joint are shown. As is clear from Tables 1 and 2, the lead acid battery of the present invention has an improved life cycle number in the SAE life test as compared with the conventional lead acid battery and no cracks are generated at the joint. The main cause of the life of the lead acid battery of the present invention was a normal short circuit due to the precipitation of the active material dropped from the electrode plate grid.
