Times are based on a 50% discharged battery and may

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.

This unit maintains 12 volt batteries, keeping them at full charge. It is not
recommended for industrial applications.

healthy battery for extended periods of time. However, problems with the battery,
