Abstract
A method of casting metal straps on lugs of battery cell elements utilizes an electrically heatable mold having a strap cavity section and comprises introducing strap metal into the cavity section, conducting electrical current through the mold for heating the mold to a predetermined temperature in excess of the melting temperature of the strap metal, immersing the element lugs into the cavity, cooling the mold to a temperature below the solidification temperature of the strap metal and removing the element lugs from the cavity with straps cast thereon.
