Marine battery Fullriver FFD260-12LT Full Force Series 260Ah 1,550A 12V
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

Frequently asked questions
Is this battery AGM? What is it for?
Yes. AGM (Absorbent Glass Mat) technology, 260 Ah and 12 V: sealed lead-acid, with the electrolyte held in glass fibre. It withstands more cycles than a conventional battery and copes better with heat.
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?
Before buying, measure the space in your boat: one extra millimetre can stop the hold-down clamp from closing. The Fullriver FFD260-12LT takes up 521×269×245 mm (length, width and height, terminals included).
Fullriver FFD260-12LT or Fullriver FFD260-12APW: which one to choose?
It has the same dimensions, voltage and technology as the FFD260-12LT, although it is not a manufacturer-approved equivalent. Compared with the FFD260-12LT it has the same Ah and cranking power. It costs the same. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap.
