A marine battery second to none, Deka gelled electrolyte batteries combine true deep cycling ability with spill-proof construction. The permanently locked in thixotropic gel won't spill, even if the battery is tipped upside down or cracked open.

Gel technology provides a longer deep cycle service life than comparable lead acid batteries, operates for longer times between charging, and recharges faster.
Deka gel batteries can be used in extreme hot or cold conditions. Sealed construction eliminates periodic watering, corrosive acid fumes, spills, and allows them to be installed in any position (although upside down is not recommended).
Totally maintenance free and exceptionally reliable, these long-lasting batteries are particularly well-suited for remote or sensitive applications such as ship's batteries, buoy lighting and navigation beacons, emergency power supply systems, security systems, remote telemetry, off-grid solar, oil and gas wellhead monitoring, and even trolling motors.

Their industry leading charge loss of less than 2% per month means Deka gel batteries can go for long periods during transport, storage, or not being used, and still provide power when needed.
The "Valve Regulated" cells in these batteries are designed with a positive-pressure, resealing safety release valve and durable jar and cover construction to prevent electrolyte leakage and minimize water loss throughout its service life.

Six volt GC2 batteries can be wired in parallel to create high capacity deep cycle battery banks for boat and RVs with individual components that are much lighter and easier to handle than 12 volt 8D or 4D batteries.
