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
Where it fits: the Fullriver FT1100-31 is one of our boat batteries, belongs to our Fullriver batteries and by capacity it sits among our 110Ah batteries.

Marine battery Fullriver FT1100-31 Full Throttle Series 110Ah 1,100A 12V
With 110 Ah at 12 V and 1,100 A of cold cranking current (EN), the Fullriver FT1100-31 from the Full Throttle 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 330 × 173 × 237 mm format: same 110 Ah capacity.
In short: the Fullriver FT1100-31 (110 Ah, 1100 A, 330 × 173 × 237 mm). Verified equivalent alternatives: Fullriver FFD110-12 and Fullriver DC115-12A.
- Powers onboard services: lights, sounder, GPS, fridge.
- Tolerates the daily cycling of a boat in season.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Reinforced case against vibration and swell.
What the Fullriver FT1100-31 is for
On board, the Fullriver FT1100-31 provides 110 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 34.10 kg and M8 + TP28 terminals.
Dimensions, polarity and mounting
It has external dimensions of 330 × 173 × 237 mm and weighs 34.10 kg. It uses M8 + TP28 terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.
Fullriver: the maker behind the FT1100-31
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. All the Fullriver batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
The Fullriver FT1100-31: Full Throttle Series range and AGM technology
The Full Throttle Series is the Fullriver range the FT1100-31 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.
AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.
Care and maintenance
As a service battery, avoid routine discharges below 50% to extend its cycle life. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections.
Official warranty
The Fullriver FT1100-31 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
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.

Bigger sister Fullriver FT1100-31 vs Fullriver DC115-12A
Bigger sister · −105,80 €
Same family as the FT1100-31, one step up in performance. Compared with the FT1100-31 it has 5 Ah more and 340 A of cold cranking less. It costs 105,80 € less. More capacity means more runtime: worth it if your equipment takes the size and had that capacity or more; otherwise the FT1100-31 does the job.

Frequently asked questions
Is the FT1100-31 model AGM? What does this technology offer?
Yes, it is AGM. In an AGM battery such as the FT1100-31, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. Its advantages: more charge/discharge cycles than a conventional battery and better heat tolerance.
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 are the dimensions of the Fullriver FT1100-31 battery?
Check the room available in your boat, because a single millimetre too much can stop the clamp from closing. Its dimensions are 330×173×237 mm, also written 330x173x237 mm; the height already includes the terminals.
Fullriver FT1100-31 or Fullriver FFD110-12: which one to choose?
It is the smaller sister of the FT1100-31 in the same Fullriver range. Compared with the FT1100-31 it has 250 A of cold cranking less. It costs 135,10 € more. Less runtime: only if the original had that capacity and there is no room for more.
Fullriver FT1100-31 or Fullriver DC115-12A: which one to choose?
