Brand: FULLRIVER batteries Part number: DC12-12

Fullriver DC12-12 12V 12Ah is a marine battery with reinforced anti-vibration case for moorings and offshore use. Tolerates the typical daily cycles on a boat (engine start + night-time services such as lights, sonar, fridge) and holds voltage even when the hull is rolling in open sea.

Why this marine battery?

  • Marine designbuilt for boat swell and vibration
  • Dual functionstarts the engine and powers onboard services
  • Sealed and safemaintenance-free even when the boat rolls

The Fullriver DC12-12 with AGM technology is a marine battery with 12 Ah for motor and sailing boats, both for engine starting and onboard services. Measuring 151 × 99 × 101 mm, it is the direct replacement for boats fitted from the factory with a 12 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.

What the Fullriver DC12-12 is for

The Fullriver DC12-12 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 4.20 kg and F1 terminals.

Will it fit your current battery tray?

It has external dimensions of 151 × 99 × 101 mm and weighs 4.20 kg. It uses F1 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

The Fullriver DC12-12: DC range and AGM technology

The DC is the Fullriver range the DC12-12 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.

Care and maintenance

At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up. As a service battery, avoid routine discharges below 50% to extend its cycle life.

Manufacturer's warranty

The Fullriver DC12-12 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

When you get it and how to return it

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 the Fullriver DC12-12 an AGM battery and what are the benefits of AGM?

Yes. The DC12-12 from Fullriver uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for boats with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.

How is the Fullriver DC12-12 battery installed in the vehicle?

In most boats it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On boats with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

What is the service life of the DC12-12 model?

Expected lifespan of the Fullriver DC12-12 is 5 to 8 years in mild-climate boat use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.

What are the dimensions of the Fullriver DC12-12 battery?

Dimensions (length × width × height) are 151×99×101 mm — also written as 151x99x101 mm — following the European DIN standard. Always measure the space in your boat before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

Will the Fullriver DC12-12 battery fit my boat?

Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The DC12-12 typically fits a wide range of European vehicles thanks to its standard DIN case format.

What are the equivalents of the DC12-12 model?

Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop boats. See the "Equivalents" section to view recommended options at the same performance level.
