The remaining battery capacity determines the range of the B500/B500-S power wheelchair.
The following factors affect the battery capacity:
❒ Ambient temperature
❒ Age of the batteries
❒ Amount of use
❒ Charging process
Driving for an extended period of time in the lower range of the battery indicator will result in deep
discharge and therefore battery damage. In addition, there is the risk that the B500/B500-S power
wheelchair may stop due to zero battery capacity and bring the user into a dangerous situation.
The information on the nameplate of the charger must match the country-specic voltage of the
respective power supply network.
The charging receptacle of the B500/B500-S power wheelchair is located on the underside of
the control panel.
❒ Charger provided by Otto Bock.
