11.11 The range of your vehicle
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.

11.12 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.
WARNINGS!
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.
