To charge the batteries using the o-board charger:
1. Position your power chair next to a standard electrical
outlet.
2. Be certain the controller power is turned o and the
power chair is in drive mode.
3. Plug the o-board charger into the o-board charger/
programming socket on the controller. See gure 11.
4. Plug the o-board charger into the electrical outlet.
5. When the batteries are fully charged, unplug the o-
board charger from the electrical outlet and then from
the controller.
The LED lights on the charger indicate dierent charger
conditions at various times: charger power on, charging
in progress, and charging complete. If the LED does
not indicate that charging is complete within 24 hours,
unplug the charger from the outlet and contact your
Quantum Rehab Provider. Refer to the manual supplied
with the charger for a complete explanation of these
indicators.
The battery charger may have indicator lights that
illuminate under certain conditions. Refer to the
operating instructions supplied with the charger for a
complete explanation of these indicators.
Charger indication warning:
When your powerchair is plugged in to charge, your
controller will indicate charging and drive inhibit by scrolling
your battery indicator continuously (indication determined by
electronics of your power chair).
Note: Your power chair may have accessories or seat
function operation that utilize the charging circuit of the
power module for functionality and/or drive inhibit. If
you notice that your battery indicators are scrolling and
the drive is inhibited, but the charger is not plugged into
the controller then check your seating position or call
your authorized Quantum provider.
To clear this error when it occurs:
1. If the system is turned o with the charger plugged into
the controller, unplug the charger from the controller.
2. If the system is powered on, unplug the charger from the
controller then turn the system o and back on.
Battery Break-in
To break in new batteries for maximum eciency:
1. Fully recharge any new battery prior to its initial use.
This brings the battery up to about 90% of its peak
performance level.
2. Operate your power chair throughout the house and
yard. Move slowly at rst, and do not travel too far until
you become accustomed to the controls and break in
the batteries.
3. Give the batteries another full charge of at least 8 to 14
hours and operate your power chair again. The batteries
will now perform at over 90% of their potential.

4. After four or ve charging cycles, the batteries will top o at
100% charge and last for an extended period.
Frequently Asked Questions (FAQs)
How does the charger work?
The battery charger takes the standard electrical outlet
voltage (alternating current) and converts it to 24V DC (direct
current). The power chair batteries use direct current to
run your power chair. When the battery voltage is low, the
charger works harder to charge the battery. As the battery
voltage approaches full charge, the charger does not work
as hard to complete the charging cycle. When the battery
is fully charged, the amperage from the charger is nearly at
zero. This is how the charger maintains a charge but does
not overcharge the battery.
Can I use a dierent battery charger?
You should use the charger supplied with the power chair. It
is the safest, most ecient tool to charge the batteries. We
do not recommend using other types of chargers (e.g., an
automotive battery charger).
NOTE: Your power chair’s charger will not operate
after the batteries have been discharged to nearly zero
voltage. If this happens, call your Quantum Rehab
Provider for assistance.
How often must I charge the batteries?
Many factors come into play when deciding how often to
charge the batteries. You may use your power chair all day
on a daily basis or you may not use it for weeks at a time.
Daily Use
If you use your power chair on a daily basis, charge the
batteries as soon as you are nished using your power
chair. Your power chair will be ready each morning to
give you a full day’s service. It is recommended that you
charge the batteries at least 8 to 14 hours after daily
use. We recommend that you charge the batteries for an
additional 4 hours after the battery charger indicates that
charging is complete.
