NOTE: The Charger output and green light will stay ON
until the power switch on the battery charger is moved to
the OFF position.

1. Attach the battery charger connector to the charger
port on the FRONT of the joystick.
2. Plug the charger’s AC power cord, or extension, into
the grounded 120 VAC wall outlet.
3. Wait until charging is complete.
NOTE: Allow eight (8) hours for normal charging. Larger
batteries (greater than 55 ampere-hours) or severely dis-
charged batteries may require up to sixteen (16) hours to
be properly charged and equalized. If the charger oper-
ates for sixteen (16) hours and is unable to fully charge
the batteries, an internal timer turns the charger off and
begins to fast blink the green light.
NOTE: If the batteries need to be charged more often or
take longer to charge than normal, they may need to be
replaced. Contact an Invacare dealer for service.
The range per battery charge using recommended bat-
teries should be approximately 5 to 9 hours of typical op-
eration. Extensive use on inclines may substantially re-
duce per charge mileage.
Description and Use of Battery Charger -
Standard 4 AMP Battery Charger
The charger automatically reduces the charge from an ini-
tially high rate to a zero reading at a fully charged condition.
NOTE: The Charger output and green light will stay ON
until the power switch on the battery charger is moved to
the OFF position.
There are some basic concepts which will help
you understand this automatic process:
The amount of electrical current drawn within a given time
to charge a battery is called “charge rate”. If, due to usage,
the charge stored in the battery is low, the charge rate is
high. As a charge builds up, the charge rate is reduced and
the battery charger rate decreases to a "trickle charge".
NOTE: If performing the charging procedures indepen-
dently, READ and CAREFULLY follow the individual in-
structions for each charger (supplied or purchased).
NOTE: If charging instructions are not supplied, consult a
qualified service technician for proper procedures.
