A battery current tapping vane is welded to a connecting strap at its one end region. The vane has weld burls and is bent over transversely to the flat side of the remaining current tapping vane. To improve the welding process and to reduce waste, the weld burls are produced in full bodied version at least in the bent end region which is provided on both sides with recesses or reduced thickness portions. The depth of the recesses or portion is greater than the amount of settlement in the course of welding on. The weld burls are alternatively formed by material archings with sides projecting transversely from the bent end region of the current tapping vane and merge into the current tapping vane, with a radius of curvature corresponding to no greater than twice the wall thickness of the current tapping vane.
