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.
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.

1.
Attach the battery charger connector to the charger port on
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.
Allow eight hours for normal charging. Larger batteries
(greater than 55 ampere-hours) or severely discharged
batteries may require up to sixteen hours to be properly
charged and equalized.
It is advantageous to recharge frequently rather than only
when necessary. In fact, a battery’s life is extended if the
charge level is maintained well above a low condition.
If the batteries need to be charged more often or take
longer to charge than normal, they may need to be replaced.
