The Fullriver FT100R marine battery offers 12 V, 8 Ah and 100 A of cold cranking current (EN) from the Full Throttle Series range with AGM technology, designed for motor and sailing boats, both for engine starting and onboard services. It replaces the original battery without adaptation in boats with a 138 × 86 × 102 mm format: same 8 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?

It has external dimensions of 138 × 86 × 102 mm and weighs 3 kg. It uses M6 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 FT100R is for

On board, the Fullriver FT100R provides 8 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 3 kg and M6 terminals.

The Fullriver FT100R: Full Throttle Series range and AGM technology

The FT100R is part of the Fullriver Full Throttle Series range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

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.

Fullriver: the maker behind the FT100R

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. We guarantee that every Fullriver arrives new, charged and with the manufacturer's full warranty.

Official warranty

The Fullriver FT100R comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

Care and maintenance

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.

Shipping, delivery 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 FT100R an AGM battery and what are the benefits of AGM?

Yes. The FT100R 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 do I fit the FT100R model in my boat?

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.

How long does the Fullriver FT100R battery last?

Expected lifespan of the Fullriver FT100R 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 FT100R battery?

Dimensions (length × width × height) are 138×86×102 mm — also written as 138x86x102 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 FT100R 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 FT100R 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.
