To charge the batteries using the optional onboard charger:
1. Position the rear of your power chair close 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 charger power lead into the charger power lead receptacle on the power base (see figure 7), then into
the electrical outlet.
NOTE: The power chair incorporates an inhibit function that disables the power chair when the charger is
plugged into an electrical outlet.
4. We recommend you charge the batteries for 8 to 14 hours. As the batteries charge, the ammeter needle slowly
drops to 0.
NOTE: The ammeter indicates how much charge is needed to fully charge the batteries. As the batteries
charge, the ammeter needle slowly drops to 0. When the batteries are fully charged, the needle vibrates on or
about the 0 mark on the ammeter.
5. When your power chair’s batteries are fully charged, disconnect the charger power lead, wind up the lead, and
store it in a safe place.
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.
Figure 25. Battery Charging
To charge the batteries using the off-board charger:
1. Position the front of your power chair next to a standard
electrical outlet. See figure 25.
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.
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.
