NOTE: After 3 minutes in Engine Start
mode, the charger will enter into a cool-
down period of 180 seconds, to allow the
charger and the battery to cool down.
6. If the engine fails to start, use the
40A Boost rate for 5 minutes before
attempting to crank the engine again.
7.
After the engine starts, move the switch
to the OFF position and unplug the AC
power cord before disconnecting the
battery clips from the vehicle.
8. Clean and store the charger in a dry
location.
NOTE: If the engine does turn over but
never starts, there is not a problem with
the starting system; there is a problem
somewhere else with the vehicle. STOP
cranking the engine until the other problem
has been diagnosed and corrected.
ABORTED CHARGE
If charging cannot be completed normally,
charging will abort. When charging aborts,
the charger’s output is shut off, and the
display will show CHARGE ABORTED -
BAD BATTERY . Do not continue
attempting to charge this battery. Have it
checked or replaced.
DESULFATION MODE
The display will show BAD BATTERY
when a sulfated battery is detected, and
the charger will go into desulfation mode.
If the desulfation is not successful after
10 hours, the charger will go into abort
mode and the display will show CHARGE
ABORTED - BAD BATTERY .
COMPLETION OF CHARGE
Charge completion is indicated by the
CHARGED/MAINTAINING
(green)
LED. When lit, the charger has switched to
the maintain mode of operation.
MAINTAIN MODE
(FLOAT MODE MONITORING)
When the CHARGED/MAINTAINING
(green) LED is lit, the charger has
started maintain mode. In this mode, the
charger keeps the battery fully charged
by delivering a small current when
necessary. If the charger has to provide
its maximum maintain current for a
continuous 12 hour period, it will go into
abort mode (see Aborted Charge section).
This is usually caused by a drain on the
battery or the battery could be bad. Make
sure there are no loads on the battery. If
there are, remove them. If there are none,
have the battery checked or replaced.
MAINTAINING A BATTERY
The FR01335 charges and maintains
6 and 12 volt batteries, keeping them at
full charge.
NOTE: The maintain mode technology
allows you to safely charge and maintain
a healthy battery for extended periods of
time. However, problems with the battery,
electrical problems in the vehicle, improper
connections or other unanticipated
conditions could cause excessive current
draws. As such, occasionally monitoring your
battery and the charging process is required.
FAN OPERATION
It is normal for the fan to be on for a while
after Engine Start operation to allow the
charger to cool down. Keep the area near
the charger clear of obstructions to allow
the fan to operate efficiently.
