Its about to get realllllly cold in MN. Expecting lows in the mid -30F and highs in the negative teens F for several days straight. We likely will not be above 0 until the weekend. I have a 2017 S75D. I was thinking of doing a couple things to manage cold weather battery issues. I've read that -25F for 24 hrs can be really bad on these batteries. Just seeing if anyone has any comments or thoughts on a better approach. For reference my car is in a garage, but it is not heated. Typically stays only 5-10 degrees warmer in the garage than outside. 1. Is it better to leave it fully charged or at my normal 75-80% ? 2. Should I "trickle" charge it overnight. Dial the charge rate way down to maybe 5-10 amps so it charges over a 5-8 hour period. 3. Can I just let it climate control all night? Bad energy use, but it'll keep the battery warmer?
