密閉形鉛蓄電池を製造することができる。FIG. 2 is a cross-sectional view of an output terminal portion of a sealed lead-acid battery using a conventionally used bolt casting 2. Bolt casting 2 is composed of lead-antimony alloy with bolt 1
Is embedded, and a part of the hole has a hole into which the pole 11 is inserted. The power generating element (not shown) is welded to a pole 11 made of a lead-antimony alloy and housed in a battery case 6. A hole is formed in the lid 7 in advance, and the pole 11 is passed through the hole. After the sealing agent sealing rubber 12 is blown from the top of the pole 11, the hole formed in the bolt casting 2 is fitted from the top of the pole 11. The sealing agent sealing rubber 12 prevents the sealing agent 10 before curing from flowing into the battery case 6. Then, the upper part of the fitting portion between the pole 11 and the bolt casting 2 is heated, melted, and solidified by a burner.
And the bolt casting 2 are welded. And, a sealing agent 10 made of an epoxy resin for preventing the electrolyte solution from rising.
Is filled into the inside of the sealing agent embedding frame 13 and cured to seal the lead storage battery. By using this method, it is possible to manufacture a good sealed lead-acid battery in which almost no creeping of the electrolytic solution is recognized.
