Battery Size
The charger automatically selects a charge
rate up to 12 amps. The charger charges
at the selected charge rate and eventually
reduces the charge rate in a controlled
manner. After the charging process has
started, the digital display can be used
to determine the charging progress by
selecting the % (Battery %) mode.
Important facts to keep in mind when
charging a battery:
• When the display indicates 77% charged,
the battery has been charged enough to
start most vehicles.
• The battery % shown in tester mode is
an estimate based on the battery voltage
and a scale set by the Battery Council
International. The battery % shown
in charger mode is an estimate of the
14. 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.
15. TROUBLESHOOTING AND ERROR CODES
Error Codes
CODE
The battery voltage is still under
10V (for a 12V battery) or 5V
F01
(for a 6V battery) after 2 hours
of charging.
The charger cannot desulfate
F02
the battery.
The battery was unable to reach
F03
the "full charge" voltage.
The connections to the battery
are reversed or are made
F04
incorrectly.
The charger was unable to
keep the battery fully charged in
F05
maintain mode.
The charger detected that the
F06
battery may be getting too hot
(thermal runaway).
DESCRIPTION
relative charge in the battery compared to
the charge it should have if the charging
process is allowed to complete.
• The battery % shown in tester mode can
be used to estimate the relative charge
time. The lower the % shown, the longer
the charge time for a given battery.
• The battery % shown in charger mode
is an indication of the relative progress
of the charging process. The higher the
battery % displayed, the less charge time
remains.
• The more a battery is discharged, the
faster it absorbs a charge from the
charger. That means that the battery %
increases faster at the beginning of the
charging process than at the end. In
other words, it takes longer for a battery
to accept the last few percent of the
charge than the first several percent.
• 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. Do not
store the clamps on the handle, clipped
together, on or around metal, or clipped to
the cables.
REASON/SOLUTION
The battery could be bad. Have it checked or
replaced.
The battery could not be desulfated; have it
checked or replaced.
Have the battery checked or replaced.
The battery is connected backwards. Or for multiple
batteries being charged, the connections are not
proper. Unplug the charger and reverse or correct
the connections to the battery(s).
The battery won't hold a charge. May be 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.
The charger automatically shuts the current off
if it detects the battery may be getting too hot.
Have the battery checked or replaced.
