[Structure] A lead storage battery includes a separator for holding an electrolytic solution, a positive electrode plate, a negative electrode plate, and a battery case. The negative electrode material contains a bisphenol condensate, and the theoretical capacity ratio between the negative electrode material and the positive electrode material is 0.85 or more and 1.2 or less. [Effect] Liquid reduction can be suppressed while improving the charge acceptance. |
