With 220 Ah at 6 V and 990 A of cold cranking current (EN), the Fullriver DC220-6 from the DC range is built for motor and sailing boats, both for engine starting and onboard services. Measuring 306 × 174 × 226 mm, it is the direct replacement for boats fitted from the factory with a 220 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.
Will it fit your current battery tray?
In terms of format, the Fullriver DC220-6 measures 306 × 174 × 226 mm (length × width × height) and weighs 32.70 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 the Fullriver DC220-6 is for
The Fullriver DC220-6 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 32.70 kg and M8 terminals.
The Fullriver DC220-6: DC range and AGM technology
Within the Fullriver catalogue, the DC series groups the references designed for this use. The DC220-6 is the 220 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.
Fullriver: the maker behind the DC220-6
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. All the Fullriver batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Official warranty
The Fullriver DC220-6 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.
Care and maintenance
As a service battery, avoid routine discharges below 50% to extend its cycle life. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections.

Frequently asked questions
Is the DC220-6 model AGM? What does this technology offer?
Yes: the DC220-6 from Fullriver uses AGM (Absorbent Glass Mat) technology, a sealed lead-acid battery whose electrolyte soaks a glass-fibre mat. It withstands more cycles than a conventional battery and copes better with heat.
In what position can it be installed on the boat?
Being AGM, it is sealed and does not spill: it can be mounted tilted (never upside down) and copes well with vibration and wave impacts. Secure it firmly and keep the terminals away from water.
What size is this battery?
Measure your boat's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. Length × width × height: 306x174x226 mm. Height is measured to the top of the terminals.
