8.5. Slow or sluggish movement
If the wheelchair does not travel at full speed or does not respond quickly enough, and the battery conditions
good, check the position of the speed control. If adjusting the speed control does not the problem then there
may be a non-hazardous fault.
9.0 Battery Gauge.
The battery gauge is included to indicate how much charge is left in the batteries. The best way to sue the
gauge is to learn how to behaves as you drive the wheelchair. Like the fuel gauge in a car, it is not completely
accurate, but it will help you avoid running out of "fuel".
The battery gauge works in the following way:
When you switch on the controller, the battery gauge shows an estimate of the remaining battery charge.
The battery gauge gives you a more accurate reading about a minute after you start driving the wheelchair.
Note: when replacing batteries, fit the recommended by the wheelchair manufacturer. If you another type the
battery gauge may be inaccurate.
The amount of the charge in the batteries depends on a number of factors. Including the way the wheelchair is
used, the temperature of the batteries, their age and the way they are made. These factors will affect the
distance the wheelchair can travel. Al wheelchair batteries will gradually lose their capacity as they age.
To make the batteries last longer, do not allow them to become completely flat. Always recharge the batteries
promptly after are discharged.
If the battery gauge reading seems to fall more quickly than usual, the batteries may be worn out.
