Marine battery Fullriver DC335-6 DC 335Ah 1,300A 6V

With 335 Ah at 6 V and 1,300 A of cold cranking current (EN), the Fullriver DC335-6 from the DC range is built for motor and sailing boats, both for engine starting and onboard services. Measuring 295 × 178 × 366 mm, it is the direct replacement for boats fitted from the factory with a 335 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.

Size, terminals and hold-down of the Fullriver DC335-6

It has external dimensions of 295 × 178 × 366 mm and weighs 47.80 kg. It uses DT 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 the Fullriver DC335-6 is for

With 335 Ah, the Fullriver DC335-6 covers motor and sailing boats, both for engine starting and onboard services. At the end of the season, charge it fully before winter storage. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 47.80 kg and DT terminals.

The Fullriver DC335-6: DC range and AGM technology

Within the Fullriver catalogue, the DC series groups the references designed for this use. The DC335-6 is the 335 Ah model of that family, with the same performance as its siblings in other sizes.

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. We guarantee that every Fullriver arrives new, charged and with the manufacturer's full warranty.

Warranty and coverage

The Fullriver DC335-6 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

Usage and maintenance tips

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.
