Instrument cluster voltate display

On the instrument cluster I was able to bring up extra function on the car. What is the UB 11.8Volt is referring to? Is it the main batter voltage or the auxilliary batter in the front? What does UB mean?

Does anybody know about this funtion on the instrument cluster?

Is that my main battery voltage? I'm not sure if my battery is about to die on me 11.6volt at no load?

Cutout stage 1 (consumer switched off) is activated when 12V systems (main) battery is > 11V, stage 2 at approximately > 10.5V.
