Brand: FULLRIVER batteries Part number: FFD260-12LT

Fullriver FFD260-12LT 12V 260Ah 1550A 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

With 260 Ah at 12 V and 1,550 A of cold cranking current (EN), the Fullriver FFD260-12LT from the Full Force Series range is built for motor and sailing boats, both for engine starting and onboard services. It replaces the original battery without adaptation in boats with a 521 × 269 × 245 mm format: same 260 Ah capacity.

  • AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
  • Reinforced case against vibration and swell.
  • Powers onboard services: lights, sounder, GPS, fridge.
  • Tolerates the daily cycling of a boat in season.

Will it fit your current battery tray?

In terms of format, the Fullriver FFD260-12LT measures 521 × 269 × 245 mm (length × width × height) and weighs 73.10 kg. It uses L Terminal 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 the Fullriver FFD260-12LT is for

On board, the Fullriver FFD260-12LT provides 260 Ah with a case reinforced against vibration and swell. Keep the terminals clean and protected from salt humidity. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 73.10 kg and L Terminal terminals.

The Fullriver FFD260-12LT: Full Force Series range and AGM technology

The Full Force Series is the Fullriver range the FFD260-12LT 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.

Fullriver: the maker behind the FFD260-12LT

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.

Official warranty

The Fullriver FFD260-12LT comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

Care and maintenance

Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up.

Shipping, delivery and returns

Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

Frequently asked questions

Is this battery AGM? What is it for?

Yes. The FFD260-12LT 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 FFD260-12LT 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 FFD260-12LT model?

Expected lifespan of the Fullriver FFD260-12LT 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 size is this battery?

Dimensions (length × width × height) are 521×269×245 mm — also written as 521x269x245 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 FFD260-12LT 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 FFD260-12LT typically fits a wide range of European vehicles thanks to its standard DIN case format.

Which interchangeable batteries are there for this one?

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.
