Invacare® FDX® Power Wheelchair Base

5.7 Charging Batteries

WARNING!
– Never attempt to recharge the batteries by attaching
cables directly to the battery terminals or clamps.
Always use the recharging plug located on the front
of the joystick.
– DO NOT sit in the wheelchair while charging the
batteries.
– DO NOT attempt to recharge the batteries and
operate the power wheelchair at the same time.
– During use and charging, unsealed batteries will
vent hydrogen gas which is explosive in the right
concentration with air.
New batteries MUST be fully charged prior to initial use
of the wheelchair.
As a general rule, batteries should be recharged daily to
assure the longest possible life and minimize the required
charging time. Plan to recharge the batteries when it is
anticipated the wheelchair will not be used for a long period
of time.
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.

5.7.1 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
or enter a trickle charge mode to maintain the batteries depending
on charger model.

There are some basic concepts which will help you understand this
automatic process. They are:
Once the charger has been connected to the wheelchair and wall
outlet and, if necessary, the charger has been turned on, the battery
charger indicator lights will flash and light to show the battery charger
status and condition of batteries to be charged. Refer to owner's
manual shipped with battery charger.
WARNING!
– NEVER leave the charger unattended when the
breaker has tripped. A fault condition exists. Unplug
and discontinue using immediately. Contact an
Invacare dealer.
If performing the charging procedures, READ and
CAREFULLY follow the individual instructions for each
charger (supplied or purchased).
If charging instructions are not supplied, consult a qualified
service technician for proper procedures.
