PURPOSE:To utilize a battery jar outer wall consisting of a lead or lead-base alloy plate as a terminal, by making the lead or lead-base alloy plate used for a partial battery jar serve as a collector body. CONSTITUTION:A positive plate 2 and a negative plate 3 or a generating element and a glass fiber-make liquid-absorbent separator 3 are held each in the shape of impregnating dilute sulfuric acid in a hole part. And, a lead-base alloy plates 1 and 1' composed of a lead-tin-calcium alloy containing tin and calcium are used for a partial battery jar while the alloy plate 1 comes into contact with the positive plate 2, and the alloy plate 1' contacts with the negative plate 4. With this constitution, a positive electrode terminal can utilize an outer surface of the alloy plate 1 and a negative electrode terminal utilizes an outer surface of the alloy plate 1', respectively, so that a projection for installing these terminals is no longer required. |
