Wheelchairs
NOTE: 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.
DESCRIPTION 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.
WARNING
NEVER leave the charger unattended when the charger circuit breaker is
tripping ON and OFF. A condition between the battery charger and batteries
exists. Contact an Invacare dealer.
NOTE: If performing the charging procedures independently, READ and CAREFULLY follow the
individual instructions for each charger (supplied or purchased).
NOTE: If charging instructions are not supplied, consult a qualified service technician for proper
procedures.
