PROBLEM TO BE SOLVED: To solve the problem that it was difficult to make small the connection body on the upper part of the battery in order to avoid occurrence of welding defect in the electric welding of the inter-cell connection penetrating through the partition wall in a mono-block lead acid storage battery. SOLUTION: An electrode tip for welding is made to start welding operation, in a state that a strap tied to the inter-cell connection body is depressed on the partition wall, thereby, even if the height of the inter-cell connection body is reduced by arranging the electrode tip at the bottom end of the electrode arm, welding defect is not generated in this inter-cell connection method, and a lead acid storage battery superior in mass and volume efficiency and low in internal resistance, and durable against vibration and impact, is obtained.
