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.
Some basic concepts which will help you understand this automatic process are:
The amount of electrical current drawn within a given time to charge a battery is called
“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.
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:
NOTE: 3-prong plug, 15 ampere current rating; industrial type
Connecting the Battery Charger
NOTE: For this procedure, refer to FIGURE 13.12.
1. Attach the battery charger connector to the charger port on the front of 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: 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.
