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. The grid also has increased structural rigidity compared to standard battery grids.
