CONSTITUTION: In a lead acid storage battery, a negative electrode material of a negative electrode plate contains graphite or carbon fibers, and barium sulfate, and has a density of 3.6 g/cmor more and 4.0 g/cmor less.EFFECT: A lead acid storage battery hardly causes permeation-induced short circuits due to graphite and is excellent in PSOC life performance.SELECTED DRAWING: Figure 1 |
