Deka Solar Batteries

Deka sealed gel cell batteries are the best battery for remote area solar applications.

solar batteryThe East-Penn Deka line of sealed gel cell batteries are field-proven with tens of thousands of solar installations all over the world. After many reviews, we have found these perform well in cold and hot climates. In cold climates. Their capacity loss is minimized due to low temperatures. In hot weather climates, these outlast traditional AGM batteries due to the Deka gel electrolyte formula.

Perfect for maintenance-free applications

The Deka Solar Battery series of valve-regulated, gel electrolyte batteries are designed to offer reliable, maintenance-free power for solar energy applications where frequent deep cycles are required and minimum maintenance is desirable.

Applications:

Remote Residential - Communications - Water Pumping - Cathodic Protection - Remote Monitoring - Vaccine Refrigeration - Tower Obstruction Lighting - SCADA - RTU - Wind Power LED Beacons - Wind Generation - DC UPS - and Much More!

Features:

  • Minimal maintenance, never needs water
  • Shock absorbent thick wall polypropylene cases
  • High purity lead calcium-tin alloy grids (patented)
  • Classified as non-hazardous, non-restricted for surface transport8G8D Battery safe for air transportation (IATA A-67)
  • Non-spillable
  • Recombination reaction (recombinant battery) prevents escape of hydrogen and oxygen gases normally lost in flooded lead-acid batteries
  • Great for deep-cycle applications
  • Deka Solar Batteries may be operated in virtually any position (upside-down is not recommended)

IMPORTANT CHARGING INSTRUCTIONS: WARRANTY VOID
IF OPENED OR IMPROPERLY CHARGED. Do not install in a
sealed container. Constant under or overcharging will damage
any battery and shorten its life! Use a good constant potential,
voltage-regulated charger. The open circuit voltage of a fully
charged 12-volt battery is 12.8V at 68°F (20°C).

Batteries manufactured in polypropylene cases and covers.
Batteries manufactured with gray case / gray cover
unless noted.

About Gel Batteries

Gel electrolyte batteries are valve regulated lead-acid. In a gel battery, the electrolyte does not flow like a normal liquid. The electrolyte has the consistency and appearance of petroleum jelly. These are considered "non-spillable".

The "acid-starved" condition of gel and AGM batteries protects the plates during heavy deep-discharges. The gel battery is more starved than an AGM battery, giving more protection to the plate; therefore, it is better suited for super-deep discharge applications. Deka Solar Batteries fit these conditions.
