In terms of format, the Fullriver DCG88-12 measures 307 × 169 × 211 mm (length × width × height) and weighs 28.40 kg. It uses M6 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### What the Fullriver DCG88-12 is for The Fullriver DCG88-12 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 28.40 kg and M6 terminals. ### The Fullriver DCG88-12: DCG range and AGM technology The DCG88-12 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 means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly. ### Why choose Fullriver batteries 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### Official warranty The Fullriver DCG88-12 comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered. ### Care and maintenance As a service battery, avoid routine discharges below 50% to extend its cycle life. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. ### Shipping, delivery 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. You have **14 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 this battery AGM? What is it for? Yes, it is AGM. In an AGM battery such as the DCG88-12, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. 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 DCG88-12 battery? The Fullriver DCG88-12 takes up 307×169×215 mm (length, width and height, terminals included). Before buying, measure the space in your boat: one extra millimetre can stop the hold-down clamp from closing. ### Fullriver DCG88-12 or Fullriver DC79-12: which one to choose? Same case and same technology as the DCG88-12: an alternative by size, not an official equivalent. Compared with the DCG88-12 it has 9 Ah less and 600 A of cold cranking more. It costs 46,30 € less. If the polarity matches and your equipment had a similar capacity, it works as a replacement; if in doubt, ask us with your model. ### Fullriver DCG88-12 or Fullriver DC90-12: which one to choose? It has the same dimensions, voltage and technology as the DCG88-12, although it is not a manufacturer-approved equivalent. Compared with the DCG88-12 it has 2 Ah more and 530 A of cold cranking more. It costs 36,90 € less. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap. ## 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*
