Measuring 271 × 170 × 189 mm, it is the direct replacement for boats fitted from the factory with a 55 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. ### Will it fit your current battery tray? The Fullriver DCG55-12 is made in the 271 × 170 × 189 mm format and weighs 19 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 DCG55-12 is for The Fullriver DCG55-12 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 19 kg and AP terminals. ### The Fullriver DCG55-12: DCG range and AGM technology The **DCG** is the Fullriver range the DCG55-12 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. 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. All the Fullriver batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Official warranty The Fullriver DCG55-12 comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered. ### How to make it last longer 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. ### When you get it and how to return it Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **14 days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is the Fullriver DCG55-12 an AGM battery and what are the benefits of AGM? Yes: the DCG55-12 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. ### 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 dimensions of the Fullriver DCG55-12 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: 271x170x189 mm (L3 case). Height is measured to the top of the terminals. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-07*
