Who knows when the hummer is charging, its blue lights are powered by which battery ? 12v battery or main battery. If I charge from a regular outlet for 24 or 36 hours, my 12v battery completely dies. I think the blue lights take power from the 12v battery when they are on, while the main battery is charging.

In a nutshell, If you’re only charging at level one, it will drain the 12V battery. You need to charge at level two for the 12V not to run down during charging.
