Deka Solar 8A31DT AGM Battery

Deka Solar AGM Battery System

The Deka 8A31DT AGM battery uses a special absorbed electrolyte technology that is superior to conventional lead-acid batteries. This completely sealed valve-regulated battery line eliminates gas emissions and acid leakage for longer and safer battery operation.

The Deka 8A31DT is a maintenance-free Group 31 Absorbed Glass Mat battery that combines true deep cycling ability with sealed, spill-proof construction for heavy demand applications. Made in the USA.

Deka 8A31DT AGM Battery Features

  • Sealed Absorbed Technology: Completely sealed; valve regulated battery with efficient recombination.
  • 250 quality control checks through ISO 9001.
  • UL recognized components MH17218.
  • Rated non-spillable by ICAO/IATA/DOT.
  • Forged terminals and bushings assure no leakage.
  • Individual plate formation (IPF®) ensures voltage matching between cells

The Deka 8A31DT AGM battery is ideal for remote solar applications such as security systems, remote telemetry, LED hazard obstruction FAA lighting, SCADA systems, pipeline monitoring, oil and gas wellhead monitoring, WiFi and WiMAX and other wireless applications.

Deka Solar 8A31DT AGM Battery Benefits

Deka Solar AGM Battery cell power grid plates
Computer-cast power path grids of a Deka AGM battery allow optimum oxygen flow between plates.

Specially-engineered safety relief valve system effectively controls critical internal gas pressure, preventing capacity loss from excessive gas seepage. This one-way valve also prevents outside air from entering the battery; a common cause of failure in most sealed valve-regulated battery designs.

Fine microfiber glass separators are highly porous to hold electrolyte more efficiently and have extremely low electrical resistance for higher capacity.

Computer-cast power path grids are pasted to uniform thickness, allowing for the exact degree of compression needed for optimum oxygen flow between the plates and separators. (Plates compressed too tightly will impede oxygen flow, while plates packed too loosely allow valuable oxygen to escape to the top of the battery. Both conditions seriously impair performance and shorten battery life.)

Exclusive individual tank formed plates provide the highest quality and most consistent performance.

Rated non-spillable by ICAO (International Commercial Airline Organization), IATA (International Airline Transport Association) and DOT (Department of Transportation) definitions.
