Brand: FULLRIVER batteries Part number: DC90-12

Fullriver DC90-12 12V 90Ah 530A 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 DC90-12 with AGM technology is a marine battery with 90 Ah and 530 A of cold cranking current (EN) for motor and sailing boats, both for engine starting and onboard services. Its 307 × 169 × 215 mm make it the exact replacement for the 90 Ah battery fitted as standard to many boats.

  • Resistant to humidity and salt air.
  • Sealed: no spills or gases in the locker.
  • Ready for starting outboard and inboard engines.
  • AGM: faster recharging and better cycle resistance than a conventional battery.

What the Fullriver DC90-12 is for

With 90 Ah, the Fullriver DC90-12 covers motor and sailing boats, both for engine starting and onboard services. 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 28.70 kg and M6 terminals.

Dimensions, polarity and mounting

In terms of format, the Fullriver DC90-12 measures 307 × 169 × 215 mm (length × width × height) and weighs 28.70 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.

The Fullriver DC90-12: DC range and AGM technology

Within the Fullriver catalogue, the DC series groups the references designed for this use. The DC90-12 is the 90 Ah model of that family, with the same performance as its siblings in other sizes.

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.

Fullriver: the maker behind the DC90-12

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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

Manufacturer's warranty

The Fullriver DC90-12 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

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. As a service battery, avoid routine discharges below 50% to extend its cycle life.

Delivery times 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 DC90-12 an AGM battery and what are the benefits of AGM?

Yes. The DC90-12 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 DC90-12 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 DC90-12 model?

Expected lifespan of the Fullriver DC90-12 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 DC90-12 battery?

Dimensions (length × width × height) are 307×169×215 mm — also written as 307x169x215 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 DC90-12 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 DC90-12 typically fits a wide range of European vehicles thanks to its standard DIN case format.

Which batteries are equivalent to the Fullriver DC90-12?

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.
