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. 10amp/hr). The higher the
number, the bigger the battery size,
weight and, potentially, the greater
the distance you can travel.
Battery pack
Your scooter is fitted with a battery
pack that requires no maintanance,
other than regular charging.
If the battery pack is physically
damaged, please use extreme
caution when handling it.
Leaking battery fluids are corrosive
and toxic.
In such an event, call your local
dealer for assistance
Please do not dispose of batteries
in normal waste, always recycle in
accordance with local laws.
Maintenance free
This is the type of battery used in
the battery pack. It uses GEL
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 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
vicinity of charging batteries.
Exclude all naked flames from
the area.
