Southern Ontario here, it was about -15C (approx 2F) without windchill today. First winter with my car. Creaks, groans, and weird sound from the HVAC aside, I did get a warning on my idrive this morning saying the battery had discharged while the car was stopped. The first crank of the day was a slow one, and I attribute it to parking outdoors overnight. Would the same reason be true for the battery warning? 2009 335 with about 44,000km (27,000 miles). After going for a bit of a drive and the engine having warmed up, I didn't get the message again.

Also if a battery tender is needed, is there a specific make or specific setting/feature that I should be looking out for?

Any feedback would be appreciated. Thanks.
