That'll just kill the 12v faster. Won't change with the range of the high volt battery.

    The main battery will have to charge the 12v battery once the latter gets low enough though

    That won't happen while the car is parked. The 12v will just die like I said, and you'll need a jump start.

    When you start the car and activate the high volt battery it will power the 12v system, including charging the 12v battery. But only once you start the car.

    I have an Ionic 6. The main battery keeps the 12 volt properly charged while parked. It doesn't just let it die.

    Interesting. When I looked into how my 5 works. I was read it was as as I described.

    I've only had it 6 months now. And it only sat parked and unplugged for an extended time, the once at the airport. So I've never really tested directly.
