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 1105 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 charging 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 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.

Can I use a different battery charger?

You should use the charger supplied with the Jazzy 1105. 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 1105’s charger will not operate after the batteries have been discharged to nearly zero voltage. If this

happens, call your authorized 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 Jazzy

1105 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 1105 on a daily basis, charge the batteries as soon as you are finished. Your Jazzy

1105 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 1105 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.

How can I get maximum range or distance per charge?

Rarely do you have an ideal driving situation such as smooth, flat, hard terrain with no wind, hills or

curves. More often you are presented with hills, sidewalk cracks, uneven and loosely packed surfaces,

curves, and wind. All of these factors affect the distance or running time per battery charge. The following

are a few suggestions for obtaining the maximum range per charge.

n Always fully charge the batteries prior to your trip.

n Maintain 30–35 psi in pneumatic drive wheels.

n Plan your trip in advance to avoid inclines if possible.

n Limit baggage weight to essential items.

n Try to maintain an even speed and avoid stop-and-go driving.
