12.0 Batteries and charging
WARNING!
Please read the owners manual with the charger supplied
carefully. The general procedures and effects for the interference
with the chair and the batteries remain valid.
WARNING!
Do not expose any part of the battery to direct heat (i.e. naked
flame, gas fire).
WARNING!
When charging always place your charger on a hard surface in a
room with good ventilation.
WARNING!
You should not charge your batteries in outdoor conditions.
12.1 Batteries
The batteries are contained within the drive unit located under
the battery shroud.
To remove the batteries first release the two handle screws
under the front of the seat frame (Fig. 12.1), which connect
the seat frame with the seat module interface.
Release and hold the safety locking pin.
Flip the seat frame backwards (Fig. 12.2) and secure it with
the safety bar like the bonnet of a car (Fig. 12.3 and 12.4).
Ensure the plastic cap is pushed over the tube to secure the
safety bar.
Lift off the battery lid.
Disconnect the 2 pin Andersen connectors from each battery
(Fig.12.5 and 12.6). There are straps available on each
battery where they can be lifted out with the front battery
being removed first.
To fit the batteries reverse the above procedure.
12.2 Safety cut-outs
In the event of a short circuit there are several safety systems
built into your wheelchair to safeguard your electrical circuits.
1. Fusible 100A links are connected into the battery harnesses
to protect the batteries and wiring.
2. 15A auxiliary power circuit fuses for auxiliary modules and
the Recaro seat power supply
3. A 70A re-settable fuse in the main controller power harness.
This is on the front shroud of the MWD and on the shroud
between the castor wheels on RWD/FWD chair.
To replace them contact your Sunrise Medical authorised dealer,
who will also diagnose the fault.
12.3 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.
12.4 General battery 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 to 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. 70amp/hr. The higher the number, the bigger the battery
size, weight and, potentially, the greater the distance you can
travel. Sunrise Medical only fit as standard maintenance free
batteries into these types of wheelchairs.
CAUTION!
Do not fit car batteries to the wheelchair. Fit only deep cycle,
maintenance free mobility batteries.
