button is not pressed within 30
seconds, the unit will search for
a battery. If the unit detects a
battery that is properly connected,
the unit will set the rate to Boost,
battery type will be set to AGM, it
will automatically start the charge
process, and the Charging (yellow/
orange) LED will light.
FAN OPERATION
The fan will operate as needed
and it is normal for the fan to
sometimes operate continuously.
Keep the area near the charger
clear of obstructions to allow the
fan to operate efficiently.
12. MAINTENANCE AND CARE
A minimal amount of care can
keep your battery charger working
properly for years.
• Clean the clamps each time you
are finished charging. Wipe off
any battery fluid that may have
come in contact with the clamps to
prevent corrosion.
• Occasionally cleaning the case
of the charger with a soft cloth
will keep the finish shiny and help
prevent corrosion.
• Coil the input and output cords
neatly when storing the charger.
This will help prevent accidental
damage to the cords and charger.
• Store the charger unplugged from
the AC power outlet in an upright
position.
• Store inside, in a cool, dry place.
Store the clamps on their support
posts, to ensure they do not come
into contact with any metallic
surface.

Error Codes
CODE
DESCRIPTION
REASON/SOLUTION
F01
The battery voltage is still under
10V (for a 12V battery) or 5V
(for a 6V battery) after 2 hours of
charging.
The battery could be bad. Have it checked or
replaced.
SUL
The charger has detected a
sulfated battery.
The charger will go into desulfation mode. If the
desulfation is not successful after 10 hours, the
charger will go into abort mode.
F02
The charger cannot desulfate
the battery.
The battery could not be desulfated; have it
checked or replaced.
F03
The battery was unable to reach
the “full charge” voltage.
May be caused by trying to charge a large battery
or bank of batteries on too low of a current setting.
Try again with a higher current setting or have the
battery checked or replaced.
F04
The connections to the battery
are reversed.
The battery is connected backwards. Unplug the
charger and reverse the connections to the battery.
F05
The charger was unable to
keep the battery fully charged in
maintain mode.
The battery won’t hold a charge. May be caused

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.
F06
The charger detected that the
battery may be getting too hot
(thermal runaway).
The charger automatically shuts the current off if
it detects the battery may be getting too hot. Have
the battery checked or replaced.
