The Solar-One battery with HuP Technology is optimized for renewable energy systems. Solar-One batteries feature a design that’s so unique, it’s patented. Engineers at EnerSys teamed up with DuPont chemists to design a flooded battery that’s so dependable, it’s backed by the longest standard warranty in the Renewable Energy industry (7 year free replacement + 3 year prorated). Solar-One batteries with HuP technology ensures that you receive more deep cycles, over its longer life, and a higher capacity for sustained performance during each cycle.

The Solar-One® with HuP® Technology

HuP® (High Utilization Positive) was created in response to another need. Patented in 1982, its original objective was to meet tough new environmental standards, and help eliminate lead dust from the battery manufacturing plant.

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. Solar One Batteries also contain Tetrafluoroethylene, or Teflon® (DuPont registered trademark for PTFE resins) to the lead paste used in active material of the positive plate.

Solar-One® uses a computerized casting which results in less flash and better crystallization during the grid molding process. The advantage is stronger, thicker positive grids that are less susceptible to corrosion.

No other battery in the Renewable Energy industry offers the technology, quality, warranty, support, and price of the Solar-One.


Each Solar-One is made up of six 2-volt cells and comes with stainless steel hardware, lead-plated copper buss bars, a cell lifting strap and an operator/installation manual. Order two for 24-volt systems or four for 48-volt systems. Many sizes are in stock and available for immediate shipment. Other sizes are made to order; please allow up to 8 weeks for delivery.

About Solar-One

Solar-One flooded batteries feature a design that's so unique, it's patented. HuP technology, created by a team of DuPont and EnerSys chemists, virtually eliminates flaking and shedding of positive materials—the main cause of battery failure. And their innovation in casting manufacturing allows production of stronger, thicker positive grids that are less susceptible to corrosion. The Solar-One positive grid is the heaviest in the industry, and allows for the maximum amount of active material in each plate.

When you buy Solar-One batteries, you'll be insured more deep cycles, a longer battery life, and a higher capacity for sustained performance during each cycle. They're so dependable, they're backed by the longest standard warranty in the Renewable Energy industry——10 years (7 year free replacement + 3 year prorated).

HuP Solar-One batteries are ideal for photovoltaic and alternative energy applications including offgrid homes or businesses, telecom, backup power, or remote outpost.

Free shipping is offered to commercial loading docks that have a forklift. If you're a homeowner, you can check with your local hardware store for a place to receive your Solar-One Batteries. For more information, call one of our experienced technicians.
