7. When your Jazzy 1120’s batteries are fully charged, you can unplug the power lead from the wall outlet, wind it up
using the hook and loop strap, and place the lead back into the electronics module.
8. Replace the rear cover.
OFF-BOARD CHARGER
If your Jazzy is equipped with an off-board charger, follow these instructions:
1. Position your Jazzy next to a standard wall outlet.
2. Be certain the controller power is turned off.
3. Remove the run plug located on the utility tray. This activates the inhibit function.
4. Plug the 3-pin extension cable into the charger, then into the utility tray connector.
5. Plug the charger into the wall outlet.
6. 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 should move all the way up to 5 amps, then gradually move back down to
0 amps.
7. We recommend you charge the batteries for 8 to 14 hours. As the batteries charge, the ammeter needle slowly
drops to zero. When the batteries are fully charged, the needle vibrates on or near zero on the ammeter scale.
8. When your Jazzy 1120’s batteries are fully charged, disconnect the charger lead from the wall outlet.
9. Disconnect the charger from the rear utility tray.
10. Reconnect the run plug into its connector.
NOTE: If the run plug is not reconnected, your Jazzy will not run.
11. Replace the rear cover.
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 Jazzy 1120 about the house and grounds. Move slowly at first, and don’t stray too far until you
become accustomed to the controls and break in the batteries.
3. Give the batteries another full charge of 8 to 14 hours and operate your Jazzy 1120 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 last for an extended period.
BATTERIES AND CHARGING—FREQUENTLY ASKED QUESTIONS (FAQS)
How does the charger work?
The battery charger takes the standard wall outlet voltage and converts it to 24 VDC (direct current). The Jazzy
1120 batteries use direct current to run your power chair. When the battery voltage is low, the charger works
harder to charge the battery. This is why the charging ammeter initially reads 5 or more amps. As the battery
voltage approaches full charge, the charger doesn’t work as hard to complete the charging cycle. This explains
why the charging ammeter drops as it approaches a full charge. When the battery is fully charged, the amperage
from the charger is nearly at zero. This is how the charger maintains a charge but does not overcharge the battery.
