Battery Replacement - Pride Mobility Jet 7 Owner's Manual

BATTERY CHARGING SYSTEM
The battery charger is essential in providing long life for your power chair's batteries. If your power chair is equipped with an off-
board charging system that plugs into the controller, see "Pilot Controller" or "Dynamic DL-50 Controller." Follow the instructions
printed on the battery charger. If your power chair is equipped with an onboard charger, follow the instructions that follow. The
onboard charger is located under the electronics tray. See figure 2.
CAUTION! To ensure prolonged life, recharge your power chair's batteries with the supplied onboard charging
system. Do not use an automotive-type battery charger!
To charge the batteries using the onboard charger:
1. Position the rear of your Jet 7 close to a standard wall outlet.
2. Be certain the controller power is turned off and the Jet 7 is not in freewheel mode.
3. Plug the charger lead into the receptacle on the connector housing.
4. Extend the charger power lead and plug it into the wall outlet. The Jet 7 incorporates an inhibit function that disables the
power chair when the charger is plugged into a wall outlet.
5. The ammeter will indicate 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 4 amps, then gradually move back down to 0 amps as it charges.
6. We recommend you charge the batteries for 8 to 14 hours. As the batteries charge, the ammeter needle will slowly drop
to the zero mark. When the batteries are fully charged, the needle will vibrate on or about the zero mark on the meter
scale.
7. When your Jet 7 batteries are fully charged, unplug the power lead from the wall outlet and from the charger receptacle
and store the lead in a safe place.
BATTERY BREAK-IN
To break in new batteries for maximum efficiency:
1. Fully recharge any new battery prior to its initial use. This brings the battery up to about 90% of its peak performance level.
2. Operate your power chair about the house and/or yard. Move slowly at first. Don't drive too far until you become
accustomed to the controls and you break-in the batteries.
3. Give the batteries another full charge of 8 to 14 hours before operating your power chair again. The batteries should now
perform at over 90% of their potential.
4. After four or five charging cycles, the batteries top off at 100% charge and should last for an extended period.

BATTERY REPLACEMENT

Follow the instructions in “Disassembly.”
WARNING! Battery posts, terminals, and related accessories contain lead and lead compounds. Wash hands

nect the battery wires from the battery terminals.

6. Place the new battery into the bottom cover.
7. Connect the red battery wire to the (+) positive terminal. Make sure you tighten the nuts and bolts so that the
