Fullriver HC28 · Wheelchair battery 28Ah 410A AGM

Mobility battery Fullriver HC28 HC 28Ah 410A 12V

The Fullriver HC28 with AGM technology delivers 28 Ah at 12 V with the cycle life that power wheelchairs, mobility scooters and light electric vehicles demand. It measures 165 × 176 × 125 mm, the format sought by anyone replacing a 28 Ah battery in power wheelchairs and mobility scooters.

• Designed to be discharged and recharged daily without losing capacity.
• AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
• Standard replacement format for wheelchairs and scooters.
• Thousands of useful cycles over its lifetime.

What the Fullriver HC28 is for

The Fullriver HC28 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 34.50 kg and M8 terminals.

Size, terminals and hold-down of the Fullriver HC28

In terms of format, the Fullriver HC28 measures 165 × 176 × 125 mm (length × width × height) and weighs 34.50 kg. It uses M8 terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

The Fullriver HC28: HC range and AGM technology

Within the Fullriver catalogue, the HC series groups the references designed for this use. The HC28 is the 28 Ah model of that family, with the same performance as its siblings in other sizes.

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.

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. We guarantee that every Fullriver arrives new, charged and with the manufacturer's full warranty.

Warranty and coverage

The Fullriver HC28 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.

Usage and maintenance tips

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity.
