PROBLEM TO BE SOLVED: To provide a sealed lead-acid battery excellent in a high efficiency discharge characteristic being high over a long period of time by restraining an increase in internal resistance at liquid reduced time, and provide an inexpensive and highly reliable sealed lead-acid battery by eliminating failure in a manufacturing process. SOLUTION: In a sealed lead-acid battery, a separator is a resilient plate-like sheet constituted by using fine glass fiber as a main component. Surface tension of electrolyte is not more than 40dyn/cm, and a fluorine type surface active agent is added to the electrolyte. |
