Our High Utilization Positive (HUP) batteries feature a design that's so unique, it's patented. Our engineers teamed up with DuPont chemists to design a flooded battery that's so dependable, it's backed by the longest standard warranty in the business (5 year full warranty + 2 years pro-rated). It ensures you receive more runs per shift, a higher capacity for sustained performance during each shift, and less maintenance downtime.

HUP offers a battery plate that virtually eliminates flaking and shedding of positive plate materials - the chief reason for battery failure. We added tetrafluorethylene, or Teflon® (Dupont registered trademark for PTFE resins.), to the lead paste used in active material of the positive plate. The Teflon forms fibers, and these fibers create a complex matrix that traps and binds the active material together. The material is then locked into place during a controlled curing process. The result - shedding and flaking are virtually eliminated, the lead paste remains cohesive, and contact with the positive grid remains in place longer than in standard batteries.
