Abstract of the Disclosure The invention relates to a method for die casting lead-alloy battery terminal connectors through an aper- ture in a plastic battery case. This involves providing a battery case containing a cellular partition and having an aperture in its wall. Molds are positioned on opposite sides of the wall to form a die mold about the aperture. One of the molds has an opening for introduction of molten lead and a heater in the opening to prevent solidification of the lead. Molten lead is then injected at a preselected pressure around the heater through the opening to form the terminal connector. This produces a connector having a significantly reduced tendency to allow leakage of battery electrolyte.
