STORAGE METALLIC FRAME OF CONTROL VALVE TYPE LEAD-ACID BATTERY

摘要

PROBLEM TO BE SOLVED: To reduce manufacturing cost and to increase longevity of a set battery main body 8 using a control valve type lead-acid battery 1. SOLUTION: A pressure plate 2 exists between a storage metallic frame 3 and the control valve type lead-acid battery 1 positioned at the top part. Thereafter, an upper surface of the control valve type lead-acid battery 1 positioned at the top part of the storage metallic frame 3 is pressurized by welding the presser plate 2 with pressure by fastening a bolt 4 set on an upper surface of the storage metallic frame 3.
