Pulled the battery and noticed it was a Duralast AGM size H8 with a Dec 2016 date code..This was an expensive battery when new. Kind of surprised it failed so soon.
I replaced it with a FRESH (Nov 2020) Ever Start H8 non-AGM battery from Walmart.
...$129 +12 core..
Back in business.

Just had the same experience in my X5. Old battery date code was 04/16 I think. Went with Sams Club, Duracell FC H8 at $121.42. 4 years is about all you get out of a battery with the electrical demands of modern BMW's I think. I now consider it a service item for 4 years replacement.
Though our E70 does a much better job of maintaining a battery with all its monitors, shuts off various systems and the like to maintain ability to start. I've left that truck for a month and it starts right up.
