Fullriver FT230L Full Throttle Series · Battery 20Ah 230A AGM

Marine battery Fullriver FT230L Full Throttle Series 20Ah 230A 12V

The Fullriver FT230L with AGM technology is a marine battery with 20 Ah and 230 A of cold cranking current (EN) 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 FT230L (20 Ah, 230 A, 181 × 77 × 167 mm). Verified equivalent alternatives: Fullriver FT230 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 FT230L is for

On board, the Fullriver FT230L provides 20 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 7 kg and M6 terminals.

Size, terminals and hold-down of the Fullriver FT230L

The Fullriver FT230L is made in the 181 × 77 × 167 mm format 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.

The Fullriver FT230L: Full Throttle Series range and AGM technology

The Full Throttle Series is the Fullriver range the FT230L 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.

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.

Why choose Fullriver batteries

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.

Warranty and coverage

The Fullriver FT230L comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

Usage and maintenance tips

Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. As a service battery, avoid routine discharges below 50% to extend its cycle life.
