To charge the batteries using the off-board
charger:
1. Position the front of your power chair next to a
standard electrical outlet.
2. Be certain the controller power is turned off
and the freewheel levers are in the engaged
position. See III. “Your Power Chair.”
3. Plug the off-board charger into the off-board
charger/programming socket on the controller.
See figure 16.
4. Plug the off-board charger into the electrical outlet.
WARNING! 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 provider. Refer to
the manual supplied with the charger for a
complete explanation of these indicators.
5. When the batteries are fully charged, unplug
the off-board charger from the electrical outlet
and then from the controller.

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 grounds. 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 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
24 VDC (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 doesn’t 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).
