Abstract: A rope holder for a battery handle rope is integral with a side of the battery case. The holder has two separate laterally spaced-apart sets of first and second passageways, the bottom opening of each passageway being unobstructed. Each passageway receives and permits passage therethrough of a length of battery handle rope having a rigid elongate lug on each end thereof. The area beneath the bottom opening of each passageway is sufficiently unobstructed to permit threading of the battery handle rope through the first and second passageways. The rigid elongate lug of the rope is secured in the upper portion of the second passageway. Upon failure of the means for securing the lug, the lug is frictionally bound in the lower portion of the second passageway because the cross-sectional area of the second passageway is less than the longitudinal length of the rigid lug. The battery handle rope is retained in the battery holder even with failure of the means for securing the lug.

Abstract: An improved rectangular shaped lead-acid storage battery grid comprises in combination, tapered vertical grid wires, tapered side and top frame wires, additional vertical grid wires disposed between the tapered vertical grid wires and two diagonal grid wires which extend from the grid portion containing the additional grid wires to the side and bottom frame wires. Not all the vertical grid wires are tapered. The last of the tapered vertical grid wires is spaced from the side frame wire adjacent the lug, a distance of more than approximately 30 per cent and up to approximately 50 per cent of the entire length of the top frame wire. The additional vertical grid wires extend downwardly from the top frame wire a distance of approximately 30 to 50 per cent of the length of the side frame wire. A battery cell made up of this type of grid has approximately 5 to 10 per cent increased high amperage discharge rate compared to a battery having a standard type of grid.
