COMPLETION OF CHARGE
Charge completion is indicated by the
Charged/Maintaining (green) LED.
When solid, the charger has switched to
maintain mode.
MAINTAIN MODE
(FLOAT MODE MONITORING)
When the Charged/Maintaining
(green) LED is solid, 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
This unit maintains 12 volt batteries,
keeping them at full charge. It can
charge and maintain both small and large
batteries.
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 on the handle, clipped
together, on or around metal, or clipped
to the cables.
