Powers the fridge, interior lighting, water pump and sockets while parked, with no need for campsite mains. Withstands daily discharges throughout the season. ## Why this caravan battery? - **Real off-grid autonomy** no campsite hookup needed - **Lasts the whole season** handles daily discharges without capacity loss - **Powers it all at once** fridge, water pump, LED and USB without issues 🔌 Voltage 6 V ⚡ Capacity 280 Ah C20 📏 Dimensions 315×180×340 mm ⚙️ Technology AGM ⚖️ Weight 46,2 kg 🏷️ Model DCG Series ## Description ## Marine battery Fullriver DCG280-6 DCG 280Ah 6V 6*V* Voltage 280*Ah* Capacity 46.20*kg* Weight The **Fullriver DCG280-6 marine battery** offers **6 V**, **280 Ah** from the **DCG** range with AGM technology, designed for motor and sailing boats, both for engine starting and onboard services. It replaces the original battery without adaptation in boats with a 315 × 180 × 340 mm format: same 280 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. ### Dimensions, polarity and mounting In terms of format, the Fullriver DCG280-6 measures 315 × 180 × 340 mm (length × width × height) and weighs 46.20 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. ### What the Fullriver DCG280-6 is for With 280 Ah, the Fullriver DCG280-6 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 46.20 kg and AP terminals. ### The Fullriver DCG280-6: DCG range and AGM technology The DCG280-6 is part of the Fullriver **DCG** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. 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. ### 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. We guarantee that every Fullriver arrives new, charged and with the manufacturer's full warranty. ### Official warranty The Fullriver DCG280-6 comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered. ### Care and maintenance Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. As a service battery, avoid routine discharges below 50% to extend its cycle life. ### When you get it and how to return it Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic and Canary Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### Is the Fullriver DCG280-6 an AGM battery and what are the benefits of AGM? Yes. The DCG280-6 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. ### How is the Fullriver DCG280-6 battery installed in the vehicle? In most boats it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On boats with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Fullriver DCG280-6 battery last? Expected lifespan of the Fullriver DCG280-6 is 5 to 8 years in mild-climate boat use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured. ### What are the dimensions of the Fullriver DCG280-6 battery? Dimensions (length × width × height) are 315×180×340 mm — also written as 315x180x340 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. ### Does this battery fit my boat? Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The DCG280-6 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which interchangeable batteries are there for this one? Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop boats. See the "Equivalents" section to view recommended options at the same performance level. ## Reviews - **Average rating**: 4.81 / 5 (12 reviews) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-06*
