ABSTRACT:
A method for manufacturing a lead grid plate for batteries comprising the first process of preparing a rolled lead alloy plate measuring 0.5 to 1 mm in thickness; the second process of press punching the rolled lead alloy plate by means of a metal mold to obtain a lead grid plate, the width of the grid forming members of the plate measuring about the same as the thickness of the plate; and the third process of hardening said lead grid plate through a heat treatment with or without a prior shape correcting process carried out before the third process.
