VIII. BATTERIES AND CHARGING
BATTERIES AND CHARGING
The Jet 2 HD 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 chair batteries. It is designed to optimize your
power chair’s performance by charging the batteries safely, quickly, and easily. The battery charging system con-
sists of the onboard battery charger, the charger circuit fuse, and the ammeter. 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 an electri-
cal outlet. The charger circuit has an ATO fuse that protects the ammeter.
WARNING! You must recharge your power chair’s batteries with the supplied onboard
battery charger. Do not use an automotive-type battery charger.
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. Failure to heed could result in personal injury and/or property damage.
PROHIBITED! Never use an extension cord to plug in your battery charger. Plug the charger
directly into a properly wired standard electrical outlet.
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 the batteries are fully charged, the needle vibrates on or about the 0 mark on the ammeter. Discon-
nect the charger power cord, wind up the cord, and store it in a safe place.
