Size, terminals and hold-down of the Fullriver HC65/B
It has external dimensions of 261 × 164 × 186 mm and weighs 9.20 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 HC65/B: HC range and AGM technology
The HC65/B is part of the Fullriver HC range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
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
Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.

Frequently asked questions
Is the Fullriver HC65/B an AGM battery and what are the benefits of AGM?
Yes: the HC65/B from Fullriver uses AGM (Absorbent Glass Mat) technology, a sealed lead-acid battery whose electrolyte soaks a glass-fibre mat. It tolerates heat better and handles more cycles than a conventional battery.
What are the measurements of the HC65/B model?
Measure your device's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. Length × width × height: 261x165x187 mm. Height is measured to the top of the terminals.
