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 18 kg and AP terminals. ### The Fullriver DCG50-12: DCG range and AGM technology The DCG50-12 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. 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. ### Size, terminals and hold-down of the Fullriver DCG50-12 The Fullriver DCG50-12 is made in the 241 × 175 × 190 mm format and weighs 18 kg. It uses AP 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 Fullriver does differently 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. ### Care and maintenance As a service battery, avoid routine discharges below 50% to extend its cycle life. At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up. ### Official warranty The Fullriver DCG50-12 comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered. ### Delivery times and returns Orders placed **before 6:00 pm** with the battery in stock ship the same day.

Yes: the DCG50-12 from Fullriver uses AGM (Absorbent Glass Mat) technology, a sealed lead-acid battery whose electrolyte soaks a glass-fibre mat. It tolerates heat better and handles more cycles than a conventional battery. ### 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? The Fullriver DCG50-12 takes up 241×175×190 mm (length, width and height, terminals included), the European L2 case size. Before buying, measure the space in your boat: one extra millimetre can stop the hold-down clamp from closing. ### Fullriver DCG50-12 or Fullriver HC50: which one to choose? Same family as the DCG50-12, one step up in performance. Compared with the DCG50-12 it has 560 A of cold cranking more. It costs 143,45 € more. More capacity means more runtime: worth it if your equipment takes the size and had that capacity or more; otherwise the DCG50-12 does the job. ## Equivalent batteries - [FULLRIVER HC50](https://baterias.com/gb/battery-fullriver-hc50-12v-50ah-560-cca) ## 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*
