9.13 the range of your vehicle:
The batteries give the chair a range of approximately 25
kilometres. Most manufacturers of mobility products state
the range of their vehicles either in the sales literature or
within the Owner’s Manual. The range stated sometimes
differs from manufacturer to manufacturer even though
the battery size is the same. Sunrise Medical measure
the range of their vehicles in a consistent and uniform
manner, but variances still occur due to motor efficiencies
and overall product load weight.
The range figures are calculated to I.S.O. Standard 7176.
Part 4: Wheelchair Energy Consumption Theoretical
Range.
This test is carried out in controlled conditions with new, fully
charg ed batteries, on a level test surface and a user weight of
100 kg. The range figures stated should be seen as a
theoretical maximum and could be reduced if any single,
or combination, of the following circumstances occur:
User weight heavier than 100 kg.
•
Batteries whose age and condition are less than
•
perfect.
The terrain is difficult e.g. very hilly, sloping, muddy
•
ground, gravel, grass, snow and ice.
The vehicle climbs kerbs regularly.
•
The ambient temperature is very hot or very cold.
•
Incorrect tyre pressures in one or more tyres.
•
Lots of start/stop driving.
•
Also thick pile carpets within the home can affect
•
range.
Use of additional power consumption options (e.g.
•
light, actuators, etc.).
The battery sizes available on each Sunrise Medical
product should give sufficient range to cope with the
majority of customer’s lifestyles.
9.14 common battery statements:
Over the years, battery technology has moved forward
but, unfortunately, some of the advice given on battery
care has not. This has resulted in a number of confused
and at times contradictory instructions on the ‘best’ way to
care for your batteries.
This section will help to dispel some of these myths and
legends.
To reduce the risk of damage to electric plug and cord,
pull by the plug rather than the cord when disconnecting
the charger. Make sure the cord is located so that it will
not be stepped on, tripped over or otherwise subjected
to damage or stress. An extension cord should not be
used unless absolutely necessary. Use of an improper
extension cord could result in a risk of fire and electric
shock. If any extension cord must be used, make sure the
pins on the plug of the extension
cord are the same number, size and shape as those of
the plug on the charger; and that the extension cord is
properly wired and in good electrical condition.
