Thanks to the interesting info in this thread. I just returned from 4 weeks of traveling, I left my garaged 2019 Bolt plugged in while gone. My charge settings are set to charge to 75%. I use a JuiceBox Charger. I use a digital multimeter to check the voltage and over the past few months my battery has ranged between 12.8v & 12.5v. I've gotten lazy and rarely record the voltage any more. I didn't record the voltage before I left on my trip, when I checked it before leaving I found it within the above mentioned range and didn't feel recording it was necessary.
When I left on my trip I left the windows rolled down and the hood open...just to cya. When I checked the battery on return it was 12.0v, charger still plugged in, green light on dash showing fully charged (to my setting of 75%). I unplugged the charger and an hour or so later the battery was at 12.3v. Still, that is the lowest reading I've measured since owning this car. Drove it today and all seemed normal.
I'll start tracking the voltage again.
