WARNING! Prevent injury and/or equipment damage! If your off-board battery charger has not
been tested and approved for outdoor use, then do not expose it to adverse or extreme weather
conditions. If the battery charger is exposed to adverse or extreme weather conditions, then it
must be allowed to adjust to the difference in environmental conditions before use indoors. Refer
to the manual supplied with the battery charger for more information.
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 power chair is in drive mode.
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.
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 cord into the charger power cord receptacle on the power base, 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 cord, wind up the cord, 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 yard. 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.
