VII. BATTERIES AND CHARGING
BATTERIES AND CHARGING
The Jazzy 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 power chairs.
WARNING! Battery posts, terminals, and related accessories contain lead and lead compounds.
Wash hands after handling.
Charging the Batteries
The battery charger is essential in providing long life for your Jazzy batteries. See figure 3. The battery charger is designed
to optimize your Jazzys performance by charging the batteries safely, quickly, and easily. The charging system consists of
the charger, the charger fuse, and the ammeter. The onboard charger is located underneath the electronics tray. See figure
3. The charger has an in-line fuse that protects the ammeter, which is located on the electronics tray for easy viewing. The
ammeter indicates the rate of charge necessary 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 a
wall outlet.
WARNING! You must recharge your Jazzys batteries with the supplied onboard or off-board
charging system. Do not use an automotive-type battery charger.
WARNING! Never use an extension cord to plug in your battery charger. Plug the charger directly
into a properly wired standard wall outlet.
To charge the batteries using the onboard charger:
1. Position the rear of your Jazzy close to a standard wall outlet.
2. Be certain the controller power is turned off and the freewheel levers are in the engaged position. See IV. The Jazzy 1101/1121.
3. Plug the charger AC power cord into the receptacle on the power base, then into the wall outlet. The Jazzy incorpo-
rates an inhibit function that disables the power chair when the charger is plugged into a wall outlet.
4. 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. We recommend you charge the batteries for 8 to 14 hours. 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.
6. When your Jazzys batteries are fully charged, wind up the charger AC power cord using the hook and loop
strap and place the cord back into the Jazzys electronics tray.
To charge the batteries using the off-board charger:
1. Position your Jazzy next to a standard wall 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 figures 21, 22a, 23, and 25.
4. Plug the off-board charger into the wall outlet.
5. 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 that came with it.
6. When the batteries are fully charged, unplug the off-board charger from the wall outlet and from the controller.
