The Fullriver HC14A, same brand and technology, stays at 14 Ah and 200 A with 15 mm less length and costs €31.40 less.

What the Fullriver HC18 is for
The Fullriver HC18 is designed for power wheelchairs, mobility scooters and light electric vehicles. Wheelchairs and scooters normally use two identical batteries in series: replace them together. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 29.80 kg and M6 terminals.
Size, terminals and hold-down of the Fullriver HC18
In terms of format, the Fullriver HC18 measures 170 × 99 × 175 mm (length × width × height) and weighs 29.80 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
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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
The Fullriver HC18: HC range and AGM technology
Within the Fullriver catalogue, the HC series groups the references designed for this use. The HC18 is the 18 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.
How to make it last longer
Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
Official warranty
The Fullriver HC18 comes with the manufacturer's official warranty against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you.

Frequently asked questions
Is the Fullriver HC18 an AGM battery and what are the benefits of AGM?
Yes. The Fullriver HC18 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.
What size is this battery?
Its dimensions are 170×99×175 mm, also written 170x99x175 mm; the height already includes the terminals. Check the room available in your device, because a single millimetre too much can stop the clamp from closing.
