<p>An improved battery design which utilizes the cover (12) of the container (10) as a mold to simultaneously create a plurality of solid cast electrical circuits, including external terminals (40, 42), all without welded connections. The battery cover (12) includes a plurality of plate strap mold wells (16) or mold wells (16) which receive molten lead. Adjacent plate strap mold wells (16) are separated by a partition wall (20). An aperture (24) is formed in the partition wall (20) which allows molten lead to flow between adjacent plate strap mold wells (16) and connect thereof. Terminal mold wells (26) have terminal apertures (28) through which molten lead flows to form an external terminal mold (14). A meltable sealant material is pre-applied to the plurality of mold wells (16) and which becomes fluid upon introduction of molten lead. Upon cooling, the sealant material (22) prevents migration of electrolyte between mold wells (16). The sealant material (22) also prevents electrolyte and gasses from leaking out of the juncture between the external terminals (40, 42) and the battery cover (12). The sealant material (22) further has the advantage of flowing into the fusion junctures between the plate lugs (36) and the plate straps (38). The plate lugs (36) may also be pre-coated when bright metal clean with a flux to prevent oxidation and a sealant (48) to retain the flux. The flux retained by the sealant (48) inhibits oxidation of the plate lugs (36).</p> |
