## Description

## Who the Fullriver HC28 is for

The Fullriver HC28 is a deep-cycle battery for electric wheelchairs: sealed, maintenance-free and built to discharge and recharge every day without losing capacity. It is fitted as a 12 V pair and takes hundreds of daily cycles, something a starter battery could not handle.
The HC28 belongs to the Fullriver FULLRIVER HC range. [See all Fullriver batteries](https://bateriasonline.es/en/fullriver-batteries)

## AGM technology in the HC28

The HC28 is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. Being sealed, the HC28 can be fitted in the boot or under a seat with no risk of spills.
