Marine battery Fullriver DCG240-12 DCG 240Ah 12V

The Fullriver DCG240-12 with AGM technology is a marine battery with 240 Ah for motor and sailing boats, both for engine starting and onboard services. It replaces the original battery without adaptation in boats with a 527 × 287 × 235 mm format: same 240 Ah capacity.

• AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
• Reinforced case against vibration and swell.
• Powers onboard services: lights, sounder, GPS, fridge.
• Tolerates the daily cycling of a boat in season.

What the Fullriver DCG240-12 is for

The Fullriver DCG240-12 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 79.70 kg and DT terminals.

The Fullriver DCG240-12: DCG range and AGM technology

Within the Fullriver catalogue, the DCG series groups the references designed for this use. The DCG240-12 is the 240 Ah model of that family, with the same performance as its siblings in other sizes.

AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.

Will it fit your current battery tray?

It has external dimensions of 527 × 287 × 235 mm and weighs 79.70 kg. It uses DT 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.

Why choose Fullriver batteries

With its own plants and a catalogue focused on high-performance AGM, Fullriver is a familiar brand in power wheelchairs, boats and photovoltaic systems that need thousands of cycles. We guarantee that every Fullriver arrives new, charged and with the manufacturer's full warranty.

How to make it last longer

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

Official warranty

The Fullriver DCG240-12 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.
