Summary:PROBLEM TO BE SOLVED: To provide a control valve type lead acid battery with three or more cells linearly formed in the same direction, for solving the problem that the deterioration of the cells, particularly, the end cells caused by a difference between their conditions during using the battery precludes a high cycle life property. SOLUTION: The control valve type lead acid battery comprises the three or more cells linearly formed in the same direction. The active material ratio of a negative electrode active material amount to a positive electrode active material amount for the cell, particularly, for the end cell is higher than the active material ratio for the center cell.
