Estimating the term…
A battery grid is disclosed. The battery grid includes a pattern of grid wires. The pattern includes a grid wire having a first segment with a first corrosion resistance and a second segment with a second corrosion resistance which is less than the first corrosion resistance. The second segment corrodes at a rate which is faster than the corrosion rate of the first segment so as to dynamically release internal stress and control grid growth of the battery grid during its service life. A battery includes said grid and a method of forming said grid are also disclosed.

A lead-acid battery comprising a plurality of stamped, positive battery grid plates each having a frame with a top, a first side, a second side, and a bottom, wherein the top has a lug, and further wherein a plurality of grid wires are interconnected within each of the frames to create interstices therebetween, the positive battery grid plates alternating with negative battery grid plates and interleaved with separators to form a stack, the stack fitting within a battery housing, the grid wires of the positive battery grid plates having a secondary deformation imparted upon the grid wires at one or more pre-selected locations.
