FORMATION METHOD FOR BATTERY JAR OF CONTROL VALVE TYPE LEAD-ACID BATTERY

PROBLEM TO BE SOLVED: To provide a method, by which what are matched with the electrolysis liquid specific gravity and the electric discharge capacity of each storage batteries connected in series, can be obtained, about a battery jar formation method of a control valve type lead storage battery, which is formed by pouring the liquid of dilute sulfuric acid, after assembling group of electrodes using the plates that are not yet formed, and making these group of electrodes contain in a battery jar. SOLUTION: An implement 20 for formation, which consists of liquid overflow prevention parts 9 according to the number of cells, and an exhaust tank 5 with air tight, which makes the upper space of each the liquid overflow prevention parts 9 share, and has a summarized exhaust valve 6 in the ceiling part of the exhaust tank 5, is equipped to the exhaust openings 2 of each cells. Then, the formation is carried out while keeping the inner pressure of each cell the same, and the exhaust valves are equipped to each the cells after the end of formation. COPYRIGHT: (C)2003,JPO
