The control valve type lead storage battery has at least one battery cell provided with a positive electrode plate, a negative electrode plate, and an electrolyte solution. The positive plate has a positive electrode material. The negative plate has a negative electrode material. The negative electrode material includes a carbonaceous material. The specific surface area Sc of the carbonaceous material based on the BET method satisfies Sc > = 650 m < 2 >/g. The content Cc of the carbonaceous material in the negative electrode material meets the condition that Cc is greater than or equal to 0.5% by mass. The control valve type lead storage battery is used for a small mobile device or a vehicle for idle stop control. 控制阀式铅蓄电池具有至少一个具备正极板、负极板以及电解液的电池单元。所述正极板具有正极电极材料。所述负极板具有负极电极材料。所述负极电极材料包含碳质材料。所述碳质材料的基于BET法的比表面积Sc满足：Sc≥650m2/g。所述负极电极材料中的所述碳质材料的含量Cc满足：Cc≥0.5质量％。控制阀式铅蓄电池例如用于小型移动装置或进行怠速停止控制的车辆。
