The "2/3" is only appropriate when reading the holding/fresh tank quantity. When using the "Battery" button that LED is actually "G" for "Good"
The Topmost light is "C" for "Charging" and will be lit as long as battery voltage is above 12.7 to 12.85 volts. It will go out when you start using the battery.
The "G" (3rd light from the bottom) will be on as long as the battery voltage falls between 12.1 and 12.15 volts (about 1/2 battery capacity used)
The "F" (2nd light from the bottom) is called "Fair" and it will stay lit as long as the voltage falls between 11.6 and 11.65 (about 80% battery used). The Fridge WILL NOT RUN below approximately 11.75 volts!
The "L" (bottom light) or "LOW" will stay on as long as the 12 volt battery is producing at least 6 volts (or VERRRRY DEAD).
You should always try to get the battery on the generator BEFORE the "G" light goes out. If the "F" light is on, you need to minimize battery use and get the battery on generator ASAP.
If the "F" Light is out you are permanently destroying battery capacity that you will never get back.
If ALL the lights are out; check your fuses and if they are good you may need to buy a new battery.
