VI. BATTERIES AND CHARGING
OFF-BOARD CHARGER
Your Jazzy may be equipped with an off-board charger. If desired, external chargers plug into the joystick control-
ler. If your Jazzy is equipped with an external charger, refer to the instructions that came with the charger.
BATTERY BREAK-IN
To break in your Jazzys new batteries for maximum efficiency:
1. Fully recharge any new battery prior to initial use. This brings the battery up to about 90% of its peak perfor-
mance.
2. Run your Jazzy 1143 about the house. Move slowly at first and dont stray too far until you become accus-
tomed to the controls and break in the batteries.
3. Give the batteries another full charge of 8 to 14 hours and run the Jazzy 1143 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 CHARGINGFREQUENTLY ASKED QUESTIONS (FAQS)
How does the charger work?
The battery charger takes the standard wall outlet voltage and converts it to 28VDC (direct current). The Jazzy
1143s batteries use direct current to run your power chair. When the battery voltage is low, the charger works
harder to charge the batteries. This is why the charging ammeter initially reads 3.5 or more amps. As the battery
voltage approaches a full charge, the charger doesnt work as hard to complete the charging cycle. This explains
why the charging ammeter drops as it approaches a full charge. When the batteries are fully charged, the amperage
from the charger is nearly zero. This is how the charger maintains a charge but does not overcharge the battery.
Your Jazzy 1143s charger will not operate after the batteries have been discharged to nearly zero voltage. If this
happens, call your authorised Pride provider for assistance.
Can I use a different battery charger?
You should use the charger supplied with the Jazzy 1143. It is the safest, most efficient way to charge the batteries.
We do not recommend using other types of chargers (e.g., an automotive battery charger).
How often must I charge the batteries?
Many factors come into play when deciding how often to charge the batteries. You may use your Jazzy 1143 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 1143 on a daily basis, charge the batteries as soon as you are finished using it for the day.
Your Jazzy 1143 will be ready each morning to give you a full days service. We recommend that you charge
the batteries 8 to 14 hours after daily use. Do not charge the batteries for more than 24 hours.
n Infrequent Use
If you use your Jazzy 1143 infrequently (once a week or less), you should charge it at least once per week for
12 to 14 hours.
