The range of your vehicle
Most manufacturers of mobility
products state the range of their
vehicles either in the sales
literature or within the Owners
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 7178, Part 4:
Scoota Energy Consumption
Theoretical Range.
This test is carried out in
controlled conditions with new,
fully charged batteries, on a level
test surface and a user weight of
75kg.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:
1. User weight heavier than 75kg.
2. Batteries whose age and
condition are less than perfect.
3. The terrain is difficult e.g. very
hilly, sloping, muddy ground,
gravel, grass, snow and ice.
4. The vehicle climbs kerbs
regularly.
5. The ambient temperature is
very hot or very cold.
6. Incorrect tyre pressures in one
or more tyres.
7. Lots of start/stop driving.
8. Also thick pile carpets within
the home can affect range.
All this technical information
may seem complicated and a
little daunting, but please
remember, that the battery sizes
available on your Sterling Elite
XS should give sufficient range
to cope with the majority of
customer’s lifestyles.
