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 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 power chairs batteries. It is designed to optimize
your power chairs performance by charging the batteries safely, quickly, and easily. The standard battery charger is
the onboard charger. The onboard charging system consists of the charger, the ammeter, the AC power cord, and the
charger fuse. These components are all located on or in the front battery box. See figure 5. 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 using the AC power cord. The charger fuse protects the ammeter from overload during charging. For battery
replacement instructions, see IX. Care and Maintenance.
WARNING! You must recharge your power chairs batteries with the supplied onboard or the optional
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 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 IV.
The Jazzy 1133.
3. Extend the charger AC power cord and plug it into the wall outlet. If your power chair uses a separate AC
power cord, plug it into the onboard AC power cord receptacle first. Your power incorporates an inhibit
function that disables the power chair when the charger is plugged into a wall outlet. This should be indicated
on the controller. See VIII. Operation.
4. Wait about a minute for the charger to warm up and check the ammeter. The ammeter indicates how much
charge is needed to fully charge the batteries. 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 chairs batteries are fully charged, wind up the charger AC power cord using the hook
and loop strap and place the cord back into the power chairs electronics tray. If your AC power cord plugs
into the onboard AC power cord receptacle as well, then roll it up and store it in a safe place.
