As far as I know if the car didn't come with a Li battery the car's battery system is pretty dumb. Which is one of the reasons I don't use them for my car. Also what oil/cheap battery did you use before that had a vent, I didn't even know that was still an option for cars, all are now the sealed type so they don't vent gas and need to manage water levels unless the battery is damaged in someway. Anyways back on topic, many Li batteries intended to be used in cars have a built in battery management system for everyday use; but I wouldn't be so sure in a nobrand ebay china battery which is why the labeling I assume. But if you have a dead Li battery in the car I am not sure how to jump start/charge it without damaging it., unless you remove and charge it like you show. Even hybrids and EVs still have some sort of lead acid battery in them because they are better for many car needs then a Li battery even if they marketing says otherwise.
