OPG: Now I try to drive our Jeep at least once every two weeks.

Yep. Same here. Storage batteries don't like to sit 'idle' too long. Fact of life. We deal with it here, in Sunny SoCal.

And the older they are, the less tolerant they are. Independent of the concerns of extreme temps.

The issues EV's have is all of that, plus above and beyond, in their limitations.
