WARNING! If your 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 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. Wait about a minute for the charger to warm up. The ammeter may move as high as 5.5 amps, then gradually move back down to 0 amps as the batteries charge.
5.When your power chair’s batteries are fully charged, the needle vibrates on or about the 0 mark on the ammeter. 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.
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 authorized Pride Provider for assistance.
