Vi. Batteries And Charging - Pride QUANTUM 1650 Owner's Manual

V I . B A T T E R I E S A N D C H A R G I N G
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 19.
4. Plug the off-board charger into the electrical outlet.
NOTE: The LED lights on the charger indicate dif-
ferent charger conditions at various times: charger
power on, charging in progress and charging com-
plete. 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.
5. When the batteries are fully charged, the needle vibrates on or about the 0 mark on the ammeter. Disconnect
the charger power lead, wind up the lead and store it in a safe place.
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
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, contact your Quantum Rehab Dealer for assistance.
