Should I Keep My Mini Plugged In After Full Charge, or Will It Kill the Battery?

Hey, got a quick one for y’all – is it cool to leave my Mini plugged in after it's fully charged during cold weather? I've heard it might help with preconditioning the car. Anybody know if this trick actually works, or could it end up messing with the battery in the long run?

Absolutely, that shouldn't be a problem. That's the whole purpose of precon. I've used it myself on occasion as well.
