Fullriver FFD100-12 12V 100Ah 650A 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 FFD100-12 marine battery offers 12 V, 100 Ah and 650 A of cold cranking current (EN) from the Full Force Series range with AGM technology, designed for motor and sailing boats, both for engine starting and onboard services. It measures 307 × 169 × 236 mm, the format sought by anyone replacing a 100 Ah battery in boats.
- Tolerates the daily cycling of a boat in season.
- Powers onboard services: lights, sounder, GPS, fridge.
- Reinforced case against vibration and swell.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
What the Fullriver FFD100-12 is for
On board, the Fullriver FFD100-12 provides 100 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 27 kg and M6 terminals.
Size, terminals and hold-down of the Fullriver FFD100-12
The Fullriver FFD100-12 is made in the 307 × 169 × 236 mm format and weighs 27 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.
The Fullriver FFD100-12: Full Force Series range and AGM technology
Within the Fullriver catalogue, the Full Force Series series groups the references designed for this use. The FFD100-12 is the 100 Ah model of that family, with the same performance as its siblings in other sizes.
AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.
What Fullriver does differently
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.
Warranty and coverage
The Fullriver FFD100-12 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. As a service battery, avoid routine discharges below 50% to extend its cycle life.
Delivery times and returns
Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have 14 days to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

Frequently asked questions
Is the FFD100-12 model AGM? What does this technology offer?
Yes. The FFD100-12 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 FFD100-12 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.
How long does the Fullriver FFD100-12 battery last?
Expected lifespan of the Fullriver FFD100-12 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 FFD100-12 battery?
Dimensions (length × width × height) are 307×169×236 mm — also written as 307x169x236 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 FFD100-12 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 FFD100-12 typically fits a wide range of European vehicles thanks to its standard DIN case format.
Which batteries are equivalent to the Fullriver FFD100-12?
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.
