The operation of the status indicator lights:
RED FLASHING - When the red light is flashing, the AC power is applied to the charger & the microprocessor circuitry is functioning properly, but the DC output cables are not connected correctly.
RED - When the red light is on, the battery charger is in the process of fully charging the battery. In order to properly charge large capacity batteries, the charger may remain in this mode for several hours or even days.
GREEN FLASHING - When the green light is flashing, and the red light is on, the battery is greater than 80% charged and may be removed from the charger and used if necessary. Leave the battery on charge until the green light is solid whenever possible. Once the green light begins to flash, it will remain flashing until either the battery charger output current drops below 0.1 amp, or until 6 to 8 hours has elapsed.
GREEN - When the green light is lit, the battery charger is in the storage mode of charge. In this mode the charger will maintain the battery at full charge.
Step 1) Initialization: Red Light On or Red Light Flashing: Monitor Circuit verifies appropriate battery voltage levels and good electrical continuity between the battery and the charger DC output.
Step 2) Bulk Charge: Red Light On, Green Light Off: Constant Current at Full Power. Bulk Charge ends at approximately 75% to 80% of full battery recharge.
Step 3) Absorption Charge: Red Light On, Green Light Flashing: Constant Voltage at Absorption Level. This conditions the battery for optimum performance. Absorption charge ends when the battery charging current drops below the optimum recharge threshold or the absorption timer expires.
Step 4) Float Charge: Red Light Off, Green Light On. Constant Voltage at Float / Maintenance level. Keeps battery fully charged and maintains high specific gravity. Full charge reset monitor protects battery against excessive appliance current draw while charging. Float charge continues indefinitely.

The key here is battery tenders are NOT battery chargers only maintainers. They were NEVER built to be a battery charger and will not recover a dead battery. I hope this clears up some confusion.
