Mine goes between just under half to 1 section short of full. 2020 HEV "4"

You really need decent hills (lucky I have plenty) that allow regen to fill the battery up. It should never get to empty.

No it's the 12V battery that keeps car alive.
But as yours is a 2020 are you like me that we do not have a actual old fashioned 12V battery, but have the battery reset switch which will use Hybrid battery to get things going.

I've merged #7 & #8 into this thread as it covers the same subject.

Just to show you can fill up the HEV battery (this is the highest mine will go) as recuperation is disabled at that point.

Do you have the connect app? As that shows 12V battery status.
But if your car is one without the normal 12V battery it is not a issue as you have the 12V reset button as per # 6 which will charge it back up.

As a guide daughters picanto has gone a month without being started or a run and still fires up OK.
If you are leaving it longer than that there is the fuse switch in fuse box by your knee that you can flip (see manual for info on that)
