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 yard. 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 of 120 VAC (alternating current) and converts it to 24
VDC (direct current). The Jazzy 1120 batteries use direct current to run your powered wheelchair. 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 com-
plete 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.

You should use the charger supplied with the Jazzy 1120. It is the safest, most efficient tool to charge the batteries.
We do not recommend using other types of chargers (e.g., an automotive battery charger). Your Jazzy 1120’s
charger will not operate after the batteries have been discharged to nearly zero voltage. If this happens, call your
authorized provider for assistance.

Many factors come into play when deciding how often to charge the batteries. You may use your Jazzy 1120 all day
on a daily basis or you may not use it for weeks at a time.
n Daily Use
If you use your Jazzy 1120 on a daily basis, charge the batteries as soon as you are finished. Your Jazzy 1120
will be ready each morning to give you a full day’s service. It is recommended that you charge the batteries 8
to 14 hours after daily use. Do not charge the batteries for more than 24 hours at a charging cycle.
n Infrequent Use
If you use your Jazzy 1120 infrequently (once a week or less), you should charge the batteries at least once per
week for 12 to 14 hours.
NOTE: Keep your batteries fully charged and avoid deeply discharging your batteries. Do not charge the
batteries for more than 24 hours at a charging cycle.
