Marine battery Fullriver DCG55-12 DCG 55Ah 12V

The Fullriver DCG55-12 marine battery offers 12 V, 55 Ah from the DCG range with AGM technology, designed for motor and sailing boats, both for engine starting and onboard services. Measuring 271 × 170 × 189 mm, it is the direct replacement for boats fitted from the factory with a 55 Ah battery of this format.

• AGM: faster recharging and better cycle resistance than a conventional battery.
• Ready for starting outboard and inboard engines.
• Sealed: no spills or gases in the locker.
• Resistant to humidity and salt air.

Will it fit your current battery tray?

The Fullriver DCG55-12 is made in the 271 × 170 × 189 mm format and weighs 19 kg. It uses AP terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

What the Fullriver DCG55-12 is for

The Fullriver DCG55-12 is designed for motor and sailing boats, both for engine starting and onboard services. If it is your starter battery, run the services from a separate battery; if it is a service battery, avoid routinely discharging it beyond 50%. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 19 kg and AP terminals.

The Fullriver DCG55-12: DCG range and AGM technology

The DCG is the Fullriver range the DCG55-12 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.

In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.

Why choose Fullriver batteries

Fullriver specialises in deep-cycle AGM batteries for mobility, marine, solar and traction. Its DC and HC series are known for their tolerance to deep discharge and long cycle life. All the Fullriver batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

Official warranty

The Fullriver DCG55-12 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

How to make it last longer

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. As a service battery, avoid routine discharges below 50% to extend its cycle life.
