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 yard. Move slowly at first, and do not travel 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 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 last for an extended period.
Frequently Asked Questions (FAQs)
How does the charger work?
The battery charger takes the standard electrical outlet voltage of 120 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. As the battery voltage approaches full charge, the
charger doesn’t work as hard to complete the charging cycle. 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).
NOTE: Your power chair’s charger will not operate after the batteries have been discharged to nearly zero
voltage. If this happens, call your Quantum Rehab Specialist 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.
!
Daily Use
If you use your power chair on a daily basis, charge the batteries as soon as you are finished. 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.
!
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 bat-
teries for more than 24 hours at a charging cycle.
