Deka Solar 8G31 Gel Cell Battery

Deka 8G31 Solar Battery System

The Deka 8G31 gel cell battery is a maintenance-free gel cell battery that combines true deep cycling ability with sealed, spill-proof construction. Made in the USA.

Exceptionally reliable, this long-lasting Group 31 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 8G31 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.
