IX. BATTERIES AND CHARGING
3. Give the batteries another full charge of 8 to 14 hours and operate your Jet 2 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.
BATTERIES AND CHARGINGFREQUENTLY 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 Jet 2 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 five or more
amps. As the battery voltage approaches 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 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 Jet 2. 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 Jet 2s
charger will not operate after the batteries have been discharged to nearly zero voltage. If this happens, call
your authorized 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 Jet 2 all day
on a daily basis or you may not use it for weeks at a time.
n DAILY USE
If you use your Jet 2 on a daily basis, charge the batteries as soon as you are finished using you power chair.
Your Jet 2 will be ready each morning to give you a full days 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 Jet 2 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 them. 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 hills or curves. More
often you are presented with hills, sidewalk cracks, uneven and loosely packed surfaces, curves, and wind.
All of these factors will affect the distance or running time per battery charge. Below are a few suggestions
for obtaining the maximum range per charge:
n Always charge the batteries fully prior to your trip.
n Maintain 3035 psi in pneumatic drive wheels.
n Plan your trip in advance to avoid inclines if possible.
