Abstract
An grid for a lead acid battery plate includes a central plate lug, the lug preferably having an expanded base for the collection of current and the grid being constructed in such a manner that the amount of metal is concentrated in the vicinity of the lug. A unique cast-on strap design for use with the grids is also disclosed. Substantial manufacturing advantages result from the use of such grids, and the performance of the battery can be increased to the point that individual battery plates may be eliminated, resulting in lighter weight batteries and material cost savings.
Claims15
A grid for a lead acid battery, comprising:
- a generally rectangular, electrically conductive grid body having opposed top and bottom frame elements and opposed side frame elements, the grid also including a current collector lug extending from the top frame element and being centered between the side elements and wherein a plurality of spaced apart conductive wires define a grid pattern at least a portion or the wires extending in a non-parallel pattern from the top element.
A lead-acid battery comprising a plurality of cellular compartments formed by end walls and partitions, each of said compartments housing a plurality of positive and negative battery plates with separators disposed therebetween, each battery plate having a current collector lug, the lugs of the positive and negative plates being arranged respectively in spaced apart lines in each compartment, one of the lines extending along the center line of the battery.
