Marine battery Fullriver FT230 Full Throttle Series 20Ah 230A 12V

The Fullriver FT230 marine battery offers 12 V, 20 Ah and 230 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. Its 181 × 77 × 167 mm make it the exact replacement for the 20 Ah battery fitted as standard to many boats.

In short: the Fullriver FT230 (20 Ah, 230 A, 181 × 77 × 167 mm). Verified equivalent alternatives: Fullriver FT230L and Fullriver FT230D.

• 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.

What the Fullriver FT230 is for

With 20 Ah, the Fullriver FT230 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 7 kg and M6 terminals.

The Fullriver FT230: Full Throttle Series range and AGM technology

The FT230 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.

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.

Size, terminals and hold-down of the Fullriver FT230

It has external dimensions of 181 × 77 × 167 mm and weighs 7 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 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. We guarantee that every Fullriver arrives new, charged and with the manufacturer's full warranty.

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.

Official warranty

The Fullriver FT230 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.
