Batteries And Charging; Charging The Batteries - Pride Mobility Jazzy 1121 Owner's Manual

V I . B A T T E R I E S

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 are also 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 onboard battery charger is essential in providing long life for your power chair batteries. See figure 3. The onboard battery
charger is designed to optimise your power chair's 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 4. 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 lead is
plugged into a wall outlet.
NOTE: You must recharge your power chair's batteries with the supplied onboard or the optional off-board charg-
ing 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 power chair 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 III. "The Jazzy 1121."
3. Plug the charger AC power lead into the receptacle on the power base, then into the wall outlet. The power chair
incorporates 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 power chair's batteries are fully charged, wind up the charger AC power lead using the hook and loop
strap and place the lead back into the power chair's electronics tray.
To charge the batteries using the off-board charger:
1. Position your power chair 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 socket on the controller. See figures 16 and 18.
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.
