PURPOSE:To provide a sealed lead-acid battery where a terminal made up of lead-antimony(Pb-Sb) alloy whose castability and mechanical strength are good is simply and easily welded to a pole, which can prevent self-discharge of a cell due to Sb contained in the terminal. CONSTITUTION:The sealed lead-acid battery consisting of a group of plates equipped with a cylindrical pole 5 made of lead-tin(Pb-Sn) alloy, a battery jar housing a group of plates, a cover 1 wherein a hole 4 which passes through the pole 5 is made and a lead-antimony(Pb-Sb) alloy made terminal. This terminal 3 is a cylinder whose diameter is smaller than the diameter of the pole 5 and welded to a part of the upper face of the pole 5. |
