BATTERY BOX FOR LEAD STORAGE BATTERY

PROBLEM TO BE SOLVED: To provide a lead storage battery which is enabled to output high output power, by exerting pressing equal power to the entire electrode board groups contained in two or more battery cell provided in a battery box. SOLUTION: It is the battery box that stores two or more electrode board group, and the battery box is divided into two or more battery cell rooms by the inside partitions. Among these cell rooms, the size of the laminating direction of the electrode board group of the cell rooms, which are located to the both ends, is made smaller than the size of the other cell rooms, and the draw-out load from the battery cells after filling with the liquid is made to be uniform.
