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. ### When you get it and how to return it Orders placed **before 6:00 pm** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **14 days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships. ## 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. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-12*
