Batteries And Charging - Pride Mobility JET 7 Owner's Manual

BATTERIES AND CHARGING

The Jet 7 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 deep
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.
WARNING! Always protect batteries from freezing temperatures and never attempt to charge a
frozen battery. This damages the battery and may cause personal injury. Attempting to charge a
battery in freezing conditions does not prevent a battery from freezing.
Charging Your Batteries
The battery charger is one of the most important parts of your power chair. The battery charger is designed to optimize
power chair performance by charging the batteries safely, quickly and easily. The charging system consists of the charger,
the charger fuse and the ammeter. The onboard battery charger is located on the battery tray. The charger fuse and the
ammeter are located on the electronics tray. 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 an electrical outlet.
WARNING! You must recharge your power chair's batteries with the supplied onboard or off-board
charging system. Do not use an automotive-type battery charger.
PROHIBITED! Never use an extension lead to plug in your battery charger. Plug the charger directly
into a properly wired standard 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. Failure
to heed could result in personal injury and/or property damage.
To charge the batteries by using the onboard charger:
1. Position the rear of the power chair close to a standard electrical outlet.
2. Be certain that the controller power is turned off and the freewheel levers are in the engaged position. See III. "Your
Power Chair."
3. Extend the charger power lead and plug it into the electrical outlet. Your power chair incorporates an inhibit function
that disables the power chair when the charger is plugged into an electrical outlet.
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 up to as high as 5.5 amps, then gradually move back down
to 0 amps as it charges.
NOTE: We recommend you charge the batteries for 8 to 14 hours. As the batteries charge, the ammeter needle
will slowly drop to zero. When the batteries are fully charged, the needle will vibrate on or about the zero mark
on the meter scale.
4. When the batteries are fully charged, unplug the charger power leadd from the electrical outlet, wind it up and store it
for future use.
