損失となつていた。Prior art and its problems Conventionally, methods for forming straps for lead-acid batteries include inserting electrode plate ears into a strap-forming comb shape and then melting the ears with a gas burner while forming the strap. A so-called cast-on method is known in which a strap is formed by inserting an electrode plate ear into a strap-forming mold and then injecting molten lead into the mold. However, the former method has poor productivity, and the latter method has the disadvantage that weldability is not reliable. Furthermore, both methods require heating and melting the lead alloy to over 300°C using gas or electricity, which can cause discoloration or distortion of the jig, burnout of the separator, etc., resulting in large energy losses. It was becoming.
