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 FT450 is one of our boat batteries, belongs to our Fullriver batteries and by capacity it sits among our 30Ah batteries.
The Fullriver FT450 in practice
FT450 vs Fullriver FT500
The Fullriver FT450 offers 30 Ah and 450 A cold cranking in a 250 × 97 × 156 mm case. The Fullriver FT500, same brand and technology, goes up to 40 Ah and 500 A and costs €25.40 more. The difference shows on diesels and in hard winters; for a daily-driven petrol car the extra is not needed.

Marine battery Fullriver FT450 Full Throttle Series 30Ah 450A 12V
With 30 Ah at 12 V and 450 A of cold cranking current (EN), the Fullriver FT450 from the Full Throttle Series range is built for motor and sailing boats, both for engine starting and onboard services. It measures 250 × 97 × 156 mm, the format sought by anyone replacing a 30 Ah battery in boats.
- Reinforced case against vibration and swell.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Tolerates the daily cycling of a boat in season.
- Powers onboard services: lights, sounder, GPS, fridge.
Dimensions, polarity and mounting
The Fullriver FT450 is made in the 250 × 97 × 156 mm format and weighs 10.60 kg. It uses M6M 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 FT450 is for
With 30 Ah, the Fullriver FT450 covers motor and sailing boats, both for engine starting and onboard services. At the end of the season, charge it fully before winter storage. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 10.60 kg and M6M terminals.
The Fullriver FT450: Full Throttle Series range and AGM technology
The Full Throttle Series is the Fullriver range the FT450 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 (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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
Official warranty
The Fullriver FT450 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. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
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.

Frequently asked questions
Is this battery AGM? What is it for?
Yes. The FT450 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.
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 FT450 battery?
Dimensions (length × width × height) are 250×97×156 mm — also written as 250x97x156 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.
