I ended up with a totally dead car battery about a week after my charger arrived. The charger told me about the total discharge situation andthe manual "dead battery" function allowed me to get enough charge into the battery for the regular charging function to detect the battery and take over. At this point the charger recharged the battery as you would expect. I would suggest that you download the instruction manual from the manufacturers' website because the use of the function buttons and indicator lights is not intuitive.
