covered.

The remaining battery capacity determines the range of the 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 power wheelchair
may stop due to zero battery capacity and put the user in a dangerous situation.
