ABSTRACT:
A process for producing a lead-acid battery, in which a lead bushing cast in a lidbof an assembled lead-acid battery A and a pole inserted through an insertion hole in the lead bushing are welded together by applying a laser beam thereto. At the time of the laser welding, as desired, a jig is so placed around the lead bushing as to surround it and the laser welding is carried out.
