VI. BATTERIES AND CHARGING
To charge the batteries using the off-board charger:
1. Position your power chair next to a standard elec-
trical outlet.
2. Be certain the controller power is turned off.
3. Plug the off-board charger into the off-board
charger/programming socket on the controller. See
VII. “Operation.”
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.
NOTE: You can remove both battery boxes from the power base and charge them using the off-board charger port
located on the front battery box. The battery boxes must be connected in order to charge them. See figure 28.
WARNING! When charging through the battery boxes, never use greater than a 5-amp charging
system. Failure to comply may result in damage to your power chair.
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 don’t 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 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.
