Flat battery on 2022 outback

So many battery discussions! Installed Ancel BM300 yesterday to help get a grip on State of Charge (SOC) and consumption. Got home from town and needed to get chicken feed out of the boot. For the heck of it, checked SOC before and after opening/closing back hatch door. Cost was 0.22V. While phantom losses are real, it's pretty easy to discharge battery doing extra motor (and light) activities.
