[Also in Division B3] In electrically connecting two electrical conductors on opposite sides of a wall of an electric battery, electrically conductive material is provided between the conductors to extend through an opening in the wall, the material is softened, pressure is applied thereto in directions towards the opening and the material is allowed to solidify, the volume of the material between the conductors being not more than the original volume of the opening. Cell element assemblies 14, 16, Fig. 1, are arranged in compartments 11, 12, on opposite sides of a partition wall 10 and the upstanding conductive lead strap portions 18, 20 have vertical planar faces 32, 34 facing the wall. An elongated lead pin 44 with a reduced centre portion is passed through openings 40, 42 in the straps and through an opening 22 in the wall, being staked or burnt to the rear faces of the straps. Jaws 50, 52 connected to the secondary of a transformer are pressed against the straps to soften the reduced section of the pin and urge the planar faces of the straps against the wall. The pin is allowed to solidify to occupy part or all of the volume of the aperture in the wall. In a modification a pointed pin 56, 58, Fig. 3, is provided in each strap 501, 521 and these pins are abutted and fused together in the wall opening.
