PROBLEM TO BE SOLVED: To provide a method of manufacturing an element for a lead acid battery having strength and anticorrosiveness prevented from lowering with end plate tabs well connected to a strap without applying more bending to the tab portions than required. SOLUTION: The element manufacturing method for the lead acid battery comprises the steps of laminating a positive plate and a negative plate via a separator and connecting both plate tabs having the same polarity to form the strap, wherein the formation of the strap and the connection of the tabs are performed in the state of being compressed so that the outsidemost width between the end plate tabs having the same polarity is smaller than the outsidemost width of the strap connecting the tabs. More preferably, the used separator is one mixed with a silica powder. A decrease in life of the lead acid battery is prevented if a difference between the thickness of the element, when compressed, and the thickness of the element after inserted into a battery jar is 30% or less of the gross of the thickness of the separator to be used for the element. |
