The Fullriver FT840-24F in practice

FT840-24F vs Fullriver FT825-78

The Fullriver FT840-24F offers 75 Ah and 840 A cold cranking in a 276 × 172 × 227 mm case. The Fullriver FT825-78, same brand and technology, stays at 65 Ah and 825 A with 15 mm less length and costs €266.25 less. If you hesitate between the two at a similar price, take this one: more capacity in the same size never hurts.

The Fullriver FT840-24F marine battery offers 12 V, 75 Ah and 840 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 276 × 172 × 227 mm format: same 75 Ah capacity.

  • 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 FT840-24F is for

The Fullriver FT840-24F is designed for motor and sailing boats, both for engine starting and onboard services. If it is your starter battery, run the services from a separate battery; if it is a service battery, avoid routinely discharging it beyond 50%. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 24.50 kg and AP terminals.

Size, terminals and hold-down of the Fullriver FT840-24F

The Fullriver FT840-24F is made in the 276 × 172 × 227 mm format and weighs 24.50 kg. It uses AP 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 FT840-24F

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.

The Fullriver FT840-24F: Full Throttle Series range and AGM technology

Within the Fullriver catalogue, the Full Throttle Series series groups the references designed for this use. The FT840-24F is the 75 Ah model of that family, with the same performance as its siblings in other sizes.

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.

Usage and maintenance tips

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up.

Warranty and coverage

The Fullriver FT840-24F comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

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 Fullriver FT840-24F an AGM battery and what are the benefits of AGM?

Yes. AGM (Absorbent Glass Mat) technology, 75 Ah and 12 V: sealed lead-acid, with the electrolyte held in glass fibre. 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 FT840-24F battery?

Before buying, measure the space in your boat: one extra millimetre can stop the hold-down clamp from closing. The Fullriver FT840-24F takes up 276×172×227 mm (length, width and height, terminals included).

Fullriver FT840-24F or Fullriver FT840-24M: which one to choose?

Same case and same technology as the FT840-24F: an alternative by size, not an official equivalent. Compared with the FT840-24F it has the same Ah and cranking power. It costs 13,50 € more. If the polarity matches and your equipment had a similar capacity, it works as a replacement; if in doubt, ask us with your model.
