Frequently Asked Questions (FAQs)
How does the charger work?
The battery charger takes the standard electrical outlet voltage (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 does not 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 effi cient 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 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.
