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 75.10 kg and DT terminals. ### Size, terminals and hold-down of the Fullriver DCG220-12 It has external dimensions of 527 × 287 × 235 mm and weighs 75.10 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. ### The Fullriver DCG220-12: DCG range and AGM technology The DCG220-12 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. 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 DCG220-12 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. ### Manufacturer's warranty The Fullriver DCG220-12 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 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. ### Delivery times and returns Orders placed **before 6:00 pm** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days.

Yes: the DCG220-12 from Fullriver uses AGM (Absorbent Glass Mat) technology, a sealed lead-acid battery whose electrolyte soaks a glass-fibre mat. Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better. ### 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 size is this battery? Length × width × height: 527x287x257 mm. Height is measured to the top of the terminals. Measure your boat's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. ## 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 · 2026-11-10*
