Batteries and charging
General information
Batteries are the power source for
almost all of the modern mobility
products available today. The design of
batteries used in mobility products is
significantly different from the batteries
used to start a car for example. Car
batteries are designed to release a large
amount of power over a short period of
time, whilst mobility batteries (commonly
called deep cycle batteries) release their
power, evenly, over a long period of time.
Therefore, due to the lower production
volumes and increased technological
requirements, mobility batteries are
typically more expensive. Commonly
two 12 volt batteries are used together in
a mobility product giving a total voltage of
24 volts. The size of the battery, (e.g. its
available power) is expressed in amps
per hour (e.g. 74amp/hr). The higher the
number, the bigger the battery size,
weight and, potentially, the greater the
distance you can travel.
Battery types
Your Scoota should be fitted with a
pair of one type of either 56 or upto
74 Amp maintenance free batteries.
Always be careful handling the
battery if the battery casing is broken,
as corrosive acid may be leaking.
The capacity at 5 hrs. discharge time
= 56Ah and 74Ah.
ISO 7176-4 requirement 7.11.
Maximum size of batteries is 276mm
x 176mm x 220mm.
The batteries are interchangeable
and so can be connected to either
side.
Please do not dispose batteries,
always recycle.
Maintenance free
This type of battery uses a different
method of carrying the electrolyte
which is totally sealed within the
battery’s outer case. As the name
implies, no maintenance is required
other than regular charging. As the
battery case is sealed, you can
safely transport this type of battery
without fear of acid spilling.
Furthermore, they are approved for
transportation on aircraft.
It is recommended that the batteries
are always stored upright.
Only use dry batteries supplied by
an authorised Sunrise Dealer.
Battery care
Below is set out a battery care plan
for maintenance free batteries. This
has been agreed between Sunrise
Medical and the battery
manufacturers to enable you to get
the best out of your batteries. If a
different care plan is followed, this
may result in lower than expected
performance from your mobility
vehicle.
Note: Do not expose any part
of the battery to direct heat
and when charging always
place on a hard surface in a
room with good ventilation.
You should not charge the
batteries in outdoor
conditions.
Do not smoke when in the
vecinity of charging batteries.
Exclude all naked flames
from the area.
