VII. BATTERIES AND CHARGING
Batteries and Charging
Your power chair uses two long-lasting, 12-volt, deep-cycle batteries. These batteries are sealed and maintenance free. Since
they are sealed, there is no need to check the electrolyte (fluid) level. Deep-cycle batteries are designed to handle a longer and
deeper discharge. Though they are similar in appearance to automotive batteries, they are not interchangeable. Automotive
batteries are not designed to handle a long, deep discharge, and also are unsafe for use in powered wheelchairs.
WARNING! Battery posts, terminals, and related accessories contain lead and lead compounds.
Wash hands after handling.
WARNING! Do not use batteries that exceed the recommended type and amp-hour capacity. Do
not use batteries with different amp-hour capacities. Refer to specifications table in this manual
and in the manual suppled with the battery charger for recommended type and capacities.
Charging The Batteries
The battery charger is essential in providing long life for your power chair batteries. The battery charger is designed to
optimize your power chair’s performance by charging the batteries safely, quickly, and easily. If your power chair is
equipped with an optional onboard battery charger, the charging system consists of the battery charger, the charger fuse,
and the ammeter. The onboard charger is located underneath the electronics tray. The ammeter and charger fuse are
located on the electronics tray for easy viewing. See figure 6. The ammeter indicates the rate of charge being adminis-
tered to fully recharge the batteries. It is also a good indication of whether or not the charger is working. The ammeter
and the charger are only functional when the charger power cord is plugged into an electrical outlet.
PROHIBITED! Removal of grounding prong can create electrical hazard. If necessary, properly
install an approved 3-pronged adapter to an electrical outlet having 2-pronged plug access.
PROHIBITED! Never use an extension cord to plug in your battery charger. Plug the charger directly
into a properly wired standard electrical outlet.
WARNING! You must recharge your power chair’s batteries with the supplied off-board or optional
onboard battery charger. Do not use an automotive-type battery charger.
WARNING! Read the battery charging instructions in this manual and in the manual supplied with
the battery charger before charging the batteries.
WARNING! Do not expose the battery charger to rain or other sources of moisture unless it has
been tested for outdoor use. Refer to the manual supplied with the battery charger for more
information.
WARNING! Explosive gases may be generated while charging the batteries. Keep the power chair
and battery charger away from sources of ignition such as flames or sparks and provide adequate
ventilation when charging the batteries.
WARNING! Inspect the battery charger, wiring, and connectors for damage before each use. Contact
your Quantum Rehab Specialist if damage is found.
WARNING! Do not attempt to open the battery charger case. If the battery charger does not
appear to be working correctly, contact your Quantum Rehab Specialist.
WARNING! If the battery charger is equipped with cooling slots, then do not attempt to insert
objects through these slots.
WARNING! Do not allow unsupervised children to play near the power chair while the batteries
are charging. Pride recommends that you do not charge the batteries while the power chair is
occupied.
