ABSTRACT:
A method of forming a through-the-partition intercell connection between adjacent cell groups in a multicell, lead-acid storage battery. Plate strap lugs are positioned on either side of an aperture in a partition between adjacent cells. One of the lugs has a substantially flat face thereon abutting the partition while the other and opposing lug has a cavity formed in its partition-abutting face, which cavity is substantially axially aligned with the aperture during positioning. The battery is rotated 90.degree. such that the cavity-bearing lug lies beneath the flat-faced lug. The flat-faced lug is then arc welded through its center backside such that the melt formed flows by gravity through the aperture in the partition and into the cavity in the opposing lug. After the battery is inverted and the center backside of the cavity-bearing lug arc welded to fuse the lugs together, cold pressing the lugs together completes the connector forming process.
