With 65 Ah at 12 V and 490 A of cold cranking current (EN), the Fullriver DC65-12B from the DC range is built for motor and sailing boats, both for engine starting and onboard services. It replaces the original battery without adaptation in boats with a 261 × 171 × 186 mm format: same 65 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 DC65-12B is for

The Fullriver DC65-12B 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 21.30 kg and M8 terminals.

The Fullriver DC65-12B: DC range and AGM technology

The DC is the Fullriver range the DC65-12B 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.

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.

Dimensions, polarity and mounting

It has external dimensions of 261 × 171 × 186 mm and weighs 21.30 kg. It uses M8 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.

How to make it last longer

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.

Official warranty

The Fullriver DC65-12B comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.
