Sealed and maintenance-free. ## Why this marine battery? - **Marine design** built for boat swell and vibration - **Dual function** starts the engine and powers onboard services - **Sealed and safe** maintenance-free even when the boat rolls 🔌 Voltage 12 V ⚡ Capacity 8 Ah C20 🔋 Cold cranking 100 A EN-1 📏 Dimensions 138×86×102 mm ⚙️ Technology AGM ⚖️ Weight 3 kg 🏷️ Model Full Throttle Series ## Description ## Marine battery Fullriver FT100R Full Throttle Series 8Ah 100A 12V 12*V* Voltage 8*Ah* Capacity 100*A* Cold cranking 3*kg* Weight 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 whose electrolyte soaks a glass-fibre mat. 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 are the dimensions of the Fullriver FT100R battery? Its dimensions are 138×86×102 mm, also written 138x86x102 mm; the height already includes the terminals. Check the room available in your boat, because a single millimetre too much can stop the clamp from closing. ### Fullriver FT100R or Fullriver FT100: which one to choose? Same range and the same performance as the FT100R. Compared with the FT100R it has the same Ah and cranking power. It costs the same. Either one works; decide by price. ## Equivalent batteries - [FULLRIVER FT100](https://baterias.com/gb/battery-fullriver-ft100-12v-8ah-100a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-12*
