What the Fullriver DCG200-6 is for
With 200 Ah, the Fullriver DCG200-6 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 31.60 kg and AP terminals.
The Fullriver DCG200-6: DCG range and AGM technology
The DCG is the Fullriver range the DCG200-6 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.
Size, terminals and hold-down of the Fullriver DCG200-6
In terms of format, the Fullriver DCG200-6 measures 243 × 188 × 275 mm (length × width × height) and weighs 31.60 kg. It uses AP 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.
Fullriver: the maker behind the DCG200-6

All the Fullriver batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Usage and maintenance tips
Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up.

Frequently asked questions
Is the Fullriver DCG200-6 an AGM battery and what are the benefits of AGM?
Yes. The DCG200-6 from Fullriver uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for boats with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
Is this a starting or a service (leisure) battery?
Service: it is designed to power electronics, lights, the fridge or the windlass for hours, withstanding deep discharges. On boats with two circuits the ideal is one starting battery and one service battery.
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 are the measurements of the DCG200-6 model?
Dimensions (length × width × height) are 243×188×275 mm — also written as 243x188x275 mm — following the European DIN standard. Always measure the space in your boat before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
Fullriver DCG200-6 or Fullriver DC200-6B: which one to choose?
It has the same dimensions, voltage and technology as the DCG200-6, although it is not a manufacturer-approved equivalent. Compared with the DCG200-6 it has 1000 A of cold cranking more. It costs 53,20 € less. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap.
