6.0 Baeries, charging and range
6.1 Baeries
Baeries are the power source for almost all of the modern
mobility products available today. The design of baeries used
in mobility products is signicantly dierent to the baeries
used to start a car for example. Car baeries are designed
to release a large amount of power over a short period of
me, whilst mobility baeries (commonly called deep cycle
baeries) release their power evenly, over a long period of
me. Therefore, due to the lower producon volumes and
increased technological requirements, mobility baeries are
typically more expensive.
Commonly two 12 volt baeries are used together in a
mobility product, giving a total voltage of 24 volts. The size
of the baery (e.g. its available power) is expressed in amps
per hour e.g. 70amp/hr. The higher the number, the bigger
the baery size, weight and, potenally, the greater the
distance you can travel. Sunrise Medical only t as standard
maintenance free baeries into these types of wheelchairs.
This type of baery uses a method of carrying the electrolyte
commonly referred to as ‘gel’, that is held within the baery
case. As the name implies, no maintenance is required other
than regular charging. You can safely transport this type of
baery without fear of acid spilling. Furthermore, they are
approved for transportaon on aircra, trains and ships.
CAUTION!
• Do not t car baeries to the wheelchair. Fit only deep cycle,
maintenance free mobility baeries.
• When the baeries are worn out, take them to the local
authority disposal point.
• Do not expose any part of the baery to direct heat (i.e.
naked ame, gas re).
• Be extra cauous to reduce the risk of dropping a metal tool
onto the baery. It could spark or short circuit the baery
or other electrical parts that may cause an explosion. Also
take o all personal metal eects and dangling objects when
working on the baery.
• Return the baeries back to Sunrise Medical or directly to
the baery manufacturer for recycling, when they no longer
hold charge.
• The baery terminals need to be checked regularly for
signs of corrosion. If any corrosion is apparent, then clean
the terminals completely and re-grease the terminal using
Vaseline petroleum jelly, not ordinary grease. Ensure that
the terminal nut and bolt, cable clip and exposed cable are
completely covered with jelly.
DANGER!
• Do not expose any part of the baery to direct heat (i.e.
naked ame, gas re).
• Be extra cauous to reduce the risk of dropping a metal tool
onto the baery. It could spark or short circuit the baery
or other electrical parts that may cause an explosion. Also
take o all personal metal eects and dangling objects
when working on the baery.

DANGER!
• Do not, under any circumstances, tamper with the baeries.
If in any doubt contact your local Sunrise Medical authorised
dealer.
• Avoid contact with acid on damaged sealed type baeries or
wet baeries.
• Baery acid can cause burns to the skin as well as damage to
oors, furniture and your wheelchair.
• If baery acid comes into contact with the skin or clothing,
wash immediately with soap and water.
• If baery acid comes into contact with the eye, immediately
ood the eye with running cold water for at least 10 minutes
and seek medical aenon immediately.
• Acid spills can be neutralised with baking soda and water.
• Take care to keep baeries upright at all mes, especially
when transporng your wheelchair.
Safety cut-outs
In the event of a short circuit there are several safety systems
built into your wheelchair to safeguard your electrical circuits,
(Fig. 6.1).
1. Fusible 100A links are connected into the baery harnesses
to protect the baeries and wiring.
2. 15A auxiliary power circuit fuses for auxiliary modules and
seang power supply.
To replace them contact your Sunrise Medical authorised
dealer, who will also diagnose the original fault.
