Abstract: A flooded-type lead-acid battery in which charging is intermittently carried out in a short period of time and high-rate discharge to a load is carried out in a partial state of charge, wherein the charge acceptance and service life characteristics under PSOC are improved by using a positive plate in which the total surface area of the positive active material per unit of the plate pack volume is set in a range of 3.5 to 15.6 m 2 /cm 3 ; a negative plate with improved charge acceptance and service life performance obtained by adding a carbonaceous electrically conductive material, and a formaldehyde condensate of bisphenol and aminobenzene sulfonic acid to the negative active material; and a separator formed from a nonwoven in which a surface facing the negative plate is composed of material selected from glass, pulp, and polyolefin.
