Did the device actually come with the instruction manual you flashed on the screen? Or did you download those from a website and just superimpose it as you read the fine print Disclaimer booklet?

How do I know what kind of car battery do I have on the car? Do I have to select 12v AGM or 12v Lithium.

I read all the reviews and not one person said how to know what car battery you have?
