BAD BATTERY
If charging cannot be completed normally,
the charger’s output is shut off and the
red Bad Battery LED will light. Do
not continue attempting to charge this
battery. Check the battery and replace, if
necessary.
DESULFATION MODE
If the battery is left discharged for an
extended period of time, it could become
sulfated and not accept a normal charge.
If the charger detects a sulfated battery,
the charger will switch to a special mode
of operation designed for such batteries.
If successful, normal charging will resume
after the battery is desulfated. Desulfation
could take 8-10 hours. If desulfation fails,
the red Bad Battery LED will light.
COMPLETION OF CHARGE
Charge completion is indicated by the green
Charged LED. When lit, the charger has
switched to the maintain mode of operation.
MAINTAIN MODE
(FLOAT MODE MONITORING)
When the green Charged 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 Bad Battery 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
This unit maintains both 6 and 12 volt
batteries, keeping them at full charge.
It is not recommended for industrial
applications.
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 recommended.
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
nished charging. Wipe off any battery
uid 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
nish 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. Do not
store the clamps clipped together, on or
around metal, or clipped to the cables.
13. TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE SOLUTION
I cannot select a 6V or 12V
setting.
The charger is equipped
with Auto Voltage Detection,
which automatically detects
the voltage and charges the
battery.
No problem; this is normal.
The green Power LED
does not light when charger is
properly connected.
AC outlet is dead.
Poor electrical connection.
Check for open fuse or circuit
breaker supplying AC outlet.
Check power cord and
extension cord for a loose
tting plug.
