Abstract
A wedge-shaped end on the lug of a secondary battery plate grid which is about three-quarters inserted in the molten lead in a post collector bar mold of an automatic cast-on machine for casting this lug integrally with a plurality of lugs of other lead plate grids. The capillary action of the molten lead fills the unimmersed parts of wedge-shaped ends of the lugs to produce integral bridges of substantially uniform rectangular cross-section between the plate grids and the collector bar.
