- Reinforced case against vibration and swell.
Dimensions, polarity and mounting
It has external dimensions of 513 × 223 × 222 mm and weighs 56.40 kg. It uses M8 + TP28 (SAE) terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
What the Fullriver FT1250-4DLT is for
On board, the Fullriver FT1250-4DLT provides 175 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 56.40 kg and M8 + TP28 (SAE) terminals.
The Fullriver FT1250-4DLT: Full Throttle Series range and AGM technology
Within the Fullriver catalogue, the Full Throttle Series series groups the references designed for this use. The FT1250-4DLT is the 175 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.
Fullriver: the maker behind the FT1250-4DLT
With its own plants and a catalogue focused on high-performance AGM, Fullriver is a familiar brand in power wheelchairs, boats and photovoltaic systems that need thousands of cycles. We guarantee that every Fullriver arrives new, charged and with the manufacturer's full warranty.
Manufacturer's warranty
The Fullriver FT1250-4DLT comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.
Care and maintenance
At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections.

Frequently asked questions
Is the Fullriver FT1250-4DLT an AGM battery and what are the benefits of AGM?
Yes. The Fullriver FT1250-4DLT is AGM (Absorbent Glass Mat): sealed lead-acid, with the electrolyte absorbed in glass fibre. Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better.
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 measurements of the FT1250-4DLT model?
Length × width × height: 513x223x222 mm. Height is measured to the top of the terminals. Measure your boat's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close.
Fullriver FT1250-4DLT or Exide EP1500: which one to choose?
The Exide alternative that fits where the FT1250-4DLT goes, with the same polarity. Compared with the FT1250-4DLT it has 5 Ah more and 350 A of cold cranking less. It costs 377,50 € less. A straight swap with nothing to adapt; the difference is the price and the brand you prefer.
