SECTION 10—ELEVATE BATTERIES
Part No 1122170 71 Formula™ Powered Seating
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 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.
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.
ƽ WARNING
NEVER leave the charger unattended when the breaker has tripped. A fault condi-
tion exists. Unplug and discontinue using immediately. 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.
Required Items:
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.
NOTE: 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.
NOTE: 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.
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.
