Batteries and charging

6.1 Electrical safety protection

Your powerchair has a fuse fitted to the battery circuit
which provides a level of protection to the battery and its
wiring in the event of a short circuit. When a fuse blows
your chair will not drive and you will need to contact your
Magic Mobility agent for repair and/or replacement.

6.2 Batteries

Your powerchair has two high quality, long lasting
gel cell batteries that are sealed (non-spillable) and
maintenance free. Your powerchair has a 24V system
which is supplied by two 12V batteries (see Figure 6.1).
There is no need to check its electrolyte fluid level.
Despite being like automotive batteries, powerchair
batteries are not the same. Automotive batteries are not
designed to handle a long, deep discharge, and are not
suitable for use in powerchairs.

• Batteries have a finite life and limits on the
length they supply and store energy. You can only
charge batteries a certain number of times before
they will fail and no longer hold charge
• Do not mix and match battery manufacturers
or technology. Never mix gel cell batteries with
AGM batteries. Only use identical batteries
that have been manufactured at the same time
and that are in the same state of charge.
Batteries must always be replaced as a pair
• Battery posts, terminals and related accessories
contain lead and lead compounds, wash your hands
after touching
5900A Powerchair Owner's Manual DCR1236
• Batteries contain corrosive chemicals. Use only AGM
or gel cell batteries to reduce the risk of leakage or
explosive conditions
• When fitting batteries, ensure their terminal posts
cannot touch any part of the powerchair frame during
installation. Battery terminals are covered which
prevents them contacting the frame during normal
operation or a tip over
• Never connect a life support or auxiliary device to
a powerchair battery without a backup system. The
electrical system may fail and result in severe injury
or death to the user.

6.3 Battery run-in

Proper care of batteries during the run-in (initial care)
period is particularly important for battery life. Follow
these steps:
1) Ensure the battery is fully charged before using your
chair for the first time
2) Use the chair often and avoid excessive loads
3) Only charge batteries after capacity has decreased
to 50 per cent
4) Fully charge your powerchair, checking that the
charger indicates that the battery is fully charged
5) Never leave your powerchair more than three days
without charging during the run-in period
6) Repeat steps 2-3 for the first 5-10 uses (cycles)
to complete the run-in procedure.

6.4 Battery charging

Only use the supplied off-board charger
unless otherwise approved by Magic
Mobility. The charger is an intelligent
charger that will shut off when the batteries are charged.
The powerchair can be left on the charger for 2-3 days.
