To charge the batteries using an off-board charger:
1. Position the front of your power chair next to a standard electrical outlet.
See figure 21.
2. Be certain the controller power is turned off.
3. Plug the off-board charger into the off-board charger/program-
ming socket on the controller.
4. Plug the off-board charger into the electrical outlet.
NOTE: If it is a Pride off-board charger, then there are two
lights in it. The red light indicates that power to the off-board
charger is on. The green light indicates that the batteries are
fully charged. If it is not a Pride off-board charger, then follow
the instructions supplied by the manufacturer.
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 of 120 VAC (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 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 Dealer for assistance.
