Impact Of Alloy And Geometry On Vla Positive Grid Designs

Drew Heimer

Historically, a true 20-year life vented lead acid (VLA) battery meant a thick positive plate, usually 0.25” or thicker. New materials and improved designs have resulted in a reduction of grid corrosion and associated positive plate growth, making it possible to achieve 20-year life with thinner plates. This paper will share results of life testing and field data to show 20 years of life can be achieved with these new designs.
