The Fullriver HC65/ST: HC range and AGM technology
The HC65/ST 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.
Fullriver: the maker behind the HC65/ST
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. All the Fullriver batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

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. Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together.

Frequently asked questions
Is the Fullriver HC65/ST an AGM battery and what are the benefits of AGM?
Yes, it is AGM. In an AGM battery such as the HC65/ST, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. Its advantages: more charge/discharge cycles than a conventional battery and better heat tolerance.
What are the measurements of the HC65/ST model?
Length × width × height: 261x172x204 mm. Height is measured to the top of the terminals. Measure your device's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close.

Same case and same fitting as the HC65/ST, from MK Powered. Compared with the HC65/ST it has 10 Ah more and 825 A of cold cranking less. It costs 203,10 € less. If you want to save or the HC65/ST is out of stock, it is the safe alternative: same dimensions, same polarity and official warranty.
