To charge the batteries using the off-board charger:
1. Position your power chair next to a standard electrical
outlet.
2. Be certain the controller power is turned off and the
power chair is in drive mode.
3. Plug the off-board charger into the off-board charger/
programming socket on the controller.
See figure 9.
4. Plug the off-board charger into the electrical outlet.
5. When the batteries are fully charged, unplug the off-
board charger from the electrical outlet and then from
the controller.
The LED lights on the charger indicate different 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.
Q-Logic 3 Battery Charging Indicator
If your battery charger is connected to the controller but
not the electrical outlet, the Q-Logic 3 controller system will
display a warning to indicate the system is not charging.
See
figure 10.
To clear this error when it occurs:
1. If the system is turned off 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 off and back on.
Battery Break-in
To break in new batteries for maximum efficiency:
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 first, 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 five charging cycles, the batteries will top off 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 different battery charger?
You should use the charger supplied with the power chair. It
is the safest, most efficient 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 finished 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
