Originally developed for military needs, Optima batteries use Spiralcell technology: a six-pack of spiral-wound, lead-acid battery cells that make the battery leak-proof and more efficient in discharging and recharging. With the components locked tightly in each cell, the Optima batteries are less susceptible to vibration and shedding that shorten the lives of regular batteries. Solid cast connections between individual cells limit the number of welds and further contribute to the battery’s longevity.
