Batteries and charging
Maintenence free battery care
plan
(continued)
9 Charge the batteries once a
month for 24 hours to ensure
each battery cell is fully
charged.
10 Following all the nine points
above should result in a
healthier battery, greater range
for the vehicle user and a longer
life for your batteries.
Do not expose any part of the
battery to direct heat (i.e. naked
flame, gas fire).
When charging always place on
a hard surface in a room with
good ventilation.
You should not charge your
batteries in outdoor conditions.
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 Sunrise
Medical Sterling Scoota should
give sufficient range to cope with
the majority of customer's
lifestyles.
