What the Fullriver FT890-49 is for

On board, the Fullriver FT890-49 provides 80 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 27.70 kg and AP terminals.

Will it fit your current battery tray?

In terms of format, the Fullriver FT890-49 measures 353 × 175 × 190 mm (length × width × height) and weighs 27.70 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.

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. All the Fullriver batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

The Fullriver FT890-49: Full Throttle Series range and AGM technology

Within the Fullriver catalogue, the Full Throttle Series series groups the references designed for this use. The FT890-49 is the 80 Ah model of that family, with the same performance as its siblings in other sizes.

AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.

How to make it last longer

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections.

Manufacturer's warranty

The Fullriver FT890-49 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.
