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.
