Deka Solar 8G8D Gel Battery Enclosure

The Deka 8G8D gel cell battery is a maintenance-free sealed battery that combines true deep cycling ability with sealed, spill-proof construction. Made in the USA.

Exceptionally reliable, this long-lasting Group 8D 12 volt battery is very resistant to hot and cold temperatures. The completely maintenance free, sealed construction eliminates periodic watering, corrosive acid fumes and spills. Electrolyte will not stratify, no equalization charging required, allowing faster recharge.

The Deka 8G8D features increased durability and deep cycle ability for heavy demand applications. Stand loss of less than 2% per month means little deterioration during transport and storage. Transports easily and safely by air.

Deka 8G8D Gel Cell Battery Features

Deka Gel Pad Mounted Solar Battery System
  • Valve regulated design with sealed construction eliminates periodic watering, corrosive acid fumes and spills.
  • Gelled electrolyte will not stratify, no equalization charging required.
  • Compu-cast, power path grids and computer-controlled oxide increases durability and deep cycle ability for heavy demand applications.
  • Less than 2% stand loss per month means less deterioration during transport and storage.
  • Tank formed plates ensures voltage matching between cells.
  • Rated non-spillable by ICAO, IATA and DOT allows transportation by air safe and easy, no special containers needed.

Made in the USA
