SECTION 12—BATTERIES
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.
NEVER leave the charger unattended when the charger circuit breaker is tripping
ON and OFF. A condition between the battery charger and batteries exists. Con-
tact 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.
