I leave mine connected in the car with the charger on it (ve ss) and no issues with it

I've charged hundreds of cars with the battery in. I've also jump started thousands of cars without any issue.

A good charger that doesn't do 22v no load and has some form of smart cut off is a good start.
Ditch grandad's vintage charger that noah used to jump start his boat.

In the bad old days many systems had components rated for 15v so that's where this all started.
