Lead-acid batteries with optimum current collection at grid lugs

摘要

A grid for a lead acid battery plate with a conductive frame having a top element and a bottom frame element, with conductive wires extending from the bottom element to the top element which includes an enlarged section beneath a current collection lug and being of a size and shape so as to optimize the current flow to the lug. Other features disclosed are the conductive wire shape and spacing so that the amount of conductive material such as lead is reduced where it has been predetermined that the current flow is minimal. In addition, the grid is designed to have equidistant potential points relative to the lug to optimize current flow. The advantage of such a grid is that it maximizes performance of the battery while keeping its weight at a minimum.
