PROBLEM TO BE SOLVED: To provide a control valve-type lead storage battery by which the degradation of a control valve-type lead storage battery operated in a standby use manner owing to ripple can be avoided well and inexpensively.SOLUTION: In a control valve-type lead storage battery, the ratio (N)/(P) of a negative electrode active material total superficial area (N) to a positive electrode active material total superficial area (P) is in a range of 0.010-0.020 in the battery in a state of full charge after chemical conversion; and the ratio (n)/(p) of a negative electrode active material total amount (n) to a positive electrode active material total amount (p) is in a range of 0.4-0.7 in the battery in the state of full charge after chemical conversion. The above numeric value ranges are determined by selecting an additive agent in a process for manufacturing each electrode plate, and adjusting various kinds of parameters including a blend volume of the additive agent in preparing an active material paste, addition amounts of water and diluted sulfuric acid, and maturation and dry conditions of the electrode plates. In addition, the numeric value ranges are adjusted by a grid form, quantities of charged active materials, a chemical conversion condition, and the numbers of positive and negative electrode plates in a battery case.SELECTED DRAWING: Figure 1 |
