Marine battery Fullriver FT850-94R Full Throttle Series 85Ah 850A 12V

The Fullriver FT850-94R with AGM technology is a marine battery with 85 Ah and 850 A of cold cranking current (EN) for motor and sailing boats, both for engine starting and onboard services. Its 314 × 174 × 190 mm make it the exact replacement for the 85 Ah battery fitted as standard to many boats.

• Resistant to humidity and salt air.
• Sealed: no spills or gases in the locker.
• Ready for starting outboard and inboard engines.
• AGM: faster recharging and better cycle resistance than a conventional battery.

Will it fit your current battery tray?

The Fullriver FT850-94R is made in the 314 × 174 × 190 mm format and weighs 25.60 kg. It uses AP 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 FT850-94R is for

On board, the Fullriver FT850-94R provides 85 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 25.60 kg and AP terminals.

The Fullriver FT850-94R: Full Throttle Series range and AGM technology

Within the Fullriver catalogue, the Full Throttle Series series groups the references designed for this use. The FT850-94R is the 85 Ah model of that family, with the same performance as its siblings in other sizes.

In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.

Fullriver: the maker behind the FT850-94R

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 FT850-94R 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.
