AUTOMATIC CHARGING MODE
When an automatic charge is performed, the charger switches to the maintain
mode automatically after the battery is charged.
BATTERY CONNECTION INDICATOR
If the charger does not detect a properly connected battery, charging will not
start and the digital display will show one of two messages. If the display shows
CONNECT CLAMPS, make sure the charger is connected to the battery and the
connection points are clean and making a good connection. If the display shows
WARNING CLAMPS REVERSED, unplug the charger from the AC outlet and
reverse the connections at the battery.
CHARGE COMPLETION AND MAINTAIN MODE
(FLOAT MODE MONITORING)
Charge completion is indicated by the GREEN LED pulsing and the digital display
showing FULLY CHARGED AUTO MAINTAINING. This means that the charger
has stopped charging and has switched to the Maintain Mode of operation. NOTE:
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 28.71321 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 required.
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 up to 8 hours. If desulfation fails, charging will abort, the GREEN LED
will ash, and the display will show CHARGING ABORTED BAD BATTERY.
