Marine battery Fullriver FFD55-12 Full Force Series 55Ah 350A 12V

The Fullriver FFD55-12 with AGM technology is a marine battery with 55 Ah and 350 A of cold cranking current (EN) for motor and sailing boats, both for engine starting and onboard services. It replaces the original battery without adaptation in boats with a 229 × 138 × 212 mm format: same 55 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 FFD55-12 is for

On board, the Fullriver FFD55-12 provides 55 Ah with a case reinforced against vibration and swell. Keep the terminals clean and protected from salt humidity. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 16.40 kg and M6 terminals.

Dimensions, polarity and mounting

The Fullriver FFD55-12 is made in the 229 × 138 × 212 mm format and weighs 16.40 kg. It uses M6 terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.

The Fullriver FFD55-12: Full Force Series range and AGM technology

The FFD55-12 is part of the Fullriver Full Force Series range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

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.

What Fullriver does differently

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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

Manufacturer's warranty

The Fullriver FFD55-12 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

Care and maintenance

At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections.
