Abstract

PURPOSE:To carry out an airtightness test without touching various plugs with the hand when a storage battery is being assembled or used, with the whole plugs fitted. CONSTITUTION:In the figure, 1 is a storage battery, 2 is battery jar, 3 is a cap, 4 is an opening sealing material, and 5 is an explosion-proof exhaust plug screwing part. 6 is an explosion-proof exhaust plug and constituted from a corundum filter part 7, a holder 8 and a packing 9. Furthermore 10 is a cup-shaped body with a hole, having a gas supply hole 11 in the upper surface and covering the corundum filter part 7 of the explosion-proof exhaust plug 6 so that the opening lower end 12 airtightly contacts with the upper surface of the holder 8. With the explosion-proof exhaust plug 6 covered with the cup-shaped body with a hole 10, a gas is forced into the storage battery 1 to a given pressure from a pump 15 through the gas supply hole 11. Then, a valve 14 is closed, and a manometer 16 is used to measure whether the internal pressure of the storage battery 1 lowers or not in order to decide whether the storage battery 1 has airtightness or not.
