Marine battery Fullriver DC120-12D DC 120Ah 750A 12V

With 120 Ah at 12 V and 750 A of cold cranking current (EN), the Fullriver DC120-12D from the DC range is built for motor and sailing boats, both for engine starting and onboard services. Measuring 260 × 180 × 301 mm, it is the direct replacement for boats fitted from the factory with a 120 Ah battery of this format.

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

What the Fullriver DC120-12D is for

The Fullriver DC120-12D 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 35.60 kg and M8 terminals.

Size, terminals and hold-down of the Fullriver DC120-12D

In terms of format, the Fullriver DC120-12D measures 260 × 180 × 301 mm (length × width × height) and weighs 35.60 kg. It uses M8 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.

What Fullriver does differently

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.

The Fullriver DC120-12D: DC range and AGM technology

Within the Fullriver catalogue, the DC series groups the references designed for this use. The DC120-12D is the 120 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.

Care and maintenance

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up.

Warranty and coverage

The Fullriver DC120-12D comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.
