8.0 The Battery Gauge
The battery gauge is included to let you know how much
charge is left in your batteries. The best way for you to use the
gauge is to learn how it 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” (Fig 8.0).
The battery gauge works in the following way:
When you switch on the control system, 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.
When you replace worn out batteries, fit the type recommended
by Sunrise Medical. If you use another type the battery gauge
may be inaccurate.
The amount of charge in your batteries depends on a number
of factors, including the way you use your wheelchair, the
temperature of the batteries, their age and the way they are
made. These factors will affect the distance you can travel in
your wheelchair. All wheelchair batteries will gradually lose their
capacity as they age.
The most important factor that reduces the life of your batteries
is the amount of charge you take from the batteries before you
recharge them. Battery life is also reduced by the number of
times you charge and discharge the batteries.
To make your batteries last longer, do not allow them to
become completely flat. Always recharge your batteries
promptly after they are discharged.
If your battery gauge reading seems to fall more quickly than
usual, your batteries may be worn out.
Please consult your authorized dealer.
8.1 How to Read a Battery Gauge
If the battery gauge shows red, yellow, and green, the batteries
are charged (Fig 8.1)
.
If the battery gauge shows just red and yellow, then you should
fully charge the batteries as soon as you can (Fig 8.2)
.
If the battery gauge shows just red, either steady or flashing
slowly, then you should fully charge the batteries immediately
(Fig 8.3).
On LED Button joystick modules the colored
LEDs
correspond
to the colored bars on the LCD version (Fig 8.4).
WARNING!
Do not operate the control system if the battery is nearly
discharged. Failure to comply with this condition may leave
you stranded in an unsafe position, such as in the middle of a
road. Sunrise Medical accepts no liability for losses of any kind
arising from failure to comply with this condition.
For comprehensive instructions and advice on
Batteries
and
Battery Charging, please consult
your wheelchair Owner’s Manual and the
Owner’s Manual supplied with the Battery
Charger.
