26 www.pridemobility.com Jet 3/Rev I/Feb03
Your Jet 3 uses two long-lasting, 12-volt, deep-cycle batteries that 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 also are unsafe for use in power
chairs.

CHARGING YOUR BATTERIES
The battery charger is one of the most important parts of your Jet 3. The battery charger is designed to optimize
your Jet 3s performance by charging the batteries quickly and easily. The charging system consists of the charger,
a charger fuse, and the ammeter. The onboard charger is located between the batteries. See figure 16. The
ammeter is located on the electronics connector housing, for easy viewing. The 7.5 amp, in-line fuse is located
under the electronics connector housing. The in-line fuse protects the entire charger circuit from shorts or bad
connections. The ammeter indicates the rate of charge necessary to fully recharge the batteries. The ammeter is
also a good indication of whether or not the charger is working. The ammeter and the charger are functional only
when the charger power cord is plugged into a wall outlet.
WARNING! Battery posts, terminals, and related accessories contain lead and lead compounds.
Wash hands after handling.
WARNING! Never use an extension cord to plug in your battery charger. Plug the charger directly
into a properly wired standard wall outlet.
WARNING! Always protect batteries from freezing temperatures and never 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.
ONBOARD CHARGER
WARNING! You must recharge your Jet 3s batteries with the supplied onboard or external
charging system. Do not use an automotive-type battery charger.
