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 13.30 kg and M6 terminals. ### The Fullriver DC38-12: DC range and AGM technology The DC38-12 is part of the Fullriver **DC** 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. ### Size, terminals and hold-down of the Fullriver DC38-12 It has external dimensions of 198 × 166 × 174 mm and weighs 13.30 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. ### Fullriver: the maker behind the DC38-12 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. All the Fullriver batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Usage and maintenance tips 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. ### Warranty and coverage The Fullriver DC38-12 comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered. ### Shipping, delivery and returns Order **before 6:00 pm** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **14 days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email. ## Frequently asked questions ### Is the Fullriver DC38-12 an AGM battery and what are the benefits of AGM? Yes: the DC38-12 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. ### 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 DC38-12 takes up 198×166×171 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 DC38-12 or Fullriver DC40-12: which one to choose? The next step up from the DC38-12 in the same range and the same case. Compared with the DC38-12 it has 2 Ah more and 10 A of cold cranking more. It costs 3,85 € more. More capacity means more runtime: worth it if your equipment takes the size and had that capacity or more; otherwise the DC38-12 does the job. ## Equivalent batteries - [FULLRIVER DC40-12](https://baterias.com/gb/battery-agm-fullriver-dc40-12-12v-40ah) ## 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 · 2026-11-13*
