HUP Batteries Q & A

High Utilization Positive Plate. HuP® technology offers a battery plate that virtually eliminates flaking and shedding of positive plate materials. Flaking and shedding are the primary reasons for battery failure. We added Tetrafluoroethylene, 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.
