PROBLEM TO BE SOLVED: To provide a fluid type lead acid battery in which charging is performed intermittently for a short duration each time, and high-rate discharging to a load is performed in a partial state of charge, the lead acid battery improving charge acceptance and life characteristic under PSOC relative to the prior art.SOLUTION: A positive electrode plate which has a positive electrode active material total surface area per unit electrode plate group volume set in a range of 3.5-15.6 m/cmis used. A negative electrode plate in which a carbonaceous conductive material is added to a negative electrode active material is used. Moreover, a compound chosen from among aluminum sulfate, cationic surfactant and phosphoric acid is added to an electrolyte, thereby improving charge acceptance and life performance. |
