Times are based on a 50% discharged battery and may change, depending on
age and condition of battery.
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, reverse the connections at the
battery, and then plug the charger back in.
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
This unit maintains both 6 and 12 volt batteries, keeping them at full charge. It
can charge small batteries and maintain both small and large batteries. If you are
maintaining a fully charged large battery, you are properly utilizing the battery charger.
