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 throughout 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 again. The batteries will now perform at over
90% of their potential.
4. After four or five charging cycles, the batteries will top off at 100% charge and last for an extended period.
Frequently Asked Questions (FAQs)
How does the charger work?
The battery charger takes the standard wall outlet voltage of 110 VAC (alternating current) and converts it to 24 VDC (direct
current). The power chair 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 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 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.
Can I use a different battery charger?
You should use the charger supplied with the power chair. 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 power chair's charger will not operate
after the batteries have been discharged to nearly zero voltage. If this happens, call your authorised Pride provider for
assistance.
How often must I charge the batteries?
Many factors come into play when deciding how often to charge the batteries. You may use your power chair all day on a daily
basis or you may not use it for weeks at a time.
n Daily Use
If you use your power chair on a daily basis, charge the batteries as soon as you are finished using your power chair. Your
power chair 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 power chair 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.
