Completion of Charge
Charge completion is indicated by the 
LED. When lit, the charger has switched to the Maintain Mode of operation.
Maintain Mode (Float Mode Monitoring)
When the 
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 battery voltage drops below a preset level, the charger will go back into Charge Mode until the battery voltage returns to the full charge level, at which point the charger will return to Maintain Mode.
NOTE: The charger automatically switches between Charge Mode and Maintain Mode as necessary. The 
LED will cycle on when the battery is at full charge and off when the voltage drops below a preset level and the charger goes into Charge Mode. This cycle will continue, and the 
LED will stay on for longer periods of time as the battery becomes more fully charged.
NOTE: The maintain mode technology utilized in this maintainer 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.
