Abstract
A microporous acid-resistant resin separator has a total pore volume ratio of 55% or more and less than 75%. A negative electrode plate is made of an electrode material containing a bisphenol condensate. Thereby, a lead-acid battery can be obtained, which reduces the softening of a positive electrode material and has excellent low-temperature high rate discharge performance.
