Charging The Batteries - Invacare POWER 9000 Owner's Operator And Maintenance Manual

CHARGING THE BATTERIES (FIGURE 11)
NOTE: New batteries MUST be fully charged prior
to initial use of the chair.
WARNING
Always charge new batteries before initial use
or battery life will be reduced.
As a general rule, you should recharge your bat-
teries as frequently as possible to assure the
longest possible life and to minimize the re-
quired charging time. Plan to recharge them
when you do not anticipate using the chair for
a long period of time.
Never attempt to recharge the batteries by at-
taching cables directly to the battery terminals
or clamps. Always use the recharging plug lo-
cated on the side of the chair frame.
DO NOT attempt to recharge the batteries and
operate the power chair at the same time.
DO NOT plug the cord into the AC outlet at this
time.
The Battery Discharge Indicator (BDI) provides
informatoion on the remaining charge in the battery.
At full charge, the BDI will be GREEN. As the bat-
tery becomes discharged, the BDI will turn AMBER
(YELLOW), then RED and finally FLASHING RED.
If the BDI is FLASHING RED, the user should charge
the batteries as soon as possible.
The range per battery charge using recommended
batteries should be approximately 5 to 9 hours of
typical operation. Extensive use on inclines may
substantially reduce per charge mileage.
There are four (4) protection circuits which guard
against damage or erratic operation due to misuse
or failure. They are the:
1. Circuit Breaker
2. Fuses, located in
the battery box
NOTE: The following information pertains to the
setup procedure prior to charging.
NOTE: If performing the charging procedures in-
dependently, READ and CAREFULLY follow the
individual instructions for each charger (sup-
plied or purchased).
NOTE: If charging instructions are not supplied,
consult a qualified service technician for proper
procedures.
3. Low-voltage Lockout
4. Fail Safe
Required Items:
TOOL
Battery Charger
Extension Cord
(3-prong plug, 15 ampere current rating;
industrial type).
Description and Use of Battery Chargers
The charger automatically reduces the charge from
an initially high rate to a zero reading at a fully
charged condition. If left unattended, the charger
should automatically shut-off when full charge is
obtained.
There are some basic concepts which will help
you understand this automatic process. They
are:
The amount of electrical current drawn within a given
time to charge a battery is called the "charge rate".
If, due to usage, the charge stored in the battery is
low, the charge rate is high, as indicated by the green
light on the charger. Initially, the green light will stay
illuminated for a short period of time followed by a
longer period of off time. As a charge builds up, the
charge rate is reduced, and the green light will stay
illuminated for a longer period of time followed by a
shorter off time.
NEVER leave the charger unattended when the
circuit breaker (charger) is tripping ON and OFF.
1. Attach the battery charger connector to the
charger cable/battery harness.
NOTE: The charger cable/battery harness is lo-
cated on the same side of the wheelchair frame
as the joystick.
2. Plug the charger's AC power cord, or extension,
into the grounded 120 VAC wall outlet.
NOTE: Before using battery charger, read
manufacturer's instruction manual.
3. Wait until charging is complete.
