as expected not covered by warranty (I have extended warranty) and it cost me $465 with tax, ouch
I got a quote from Town and Country of over $360 just for the battery alone.
Screw BMW. If anyone needs a new battery you can buy MotoMaster Eliminator Ultra Flat Plate AGM Automotive Battery Groul L5/49 from Crappy Tire which is just a rebranded Exide Edge AGM Car Battery (Group L5/49). Exide is or at least was one of the OEM battery suppliers to BMW and this particular battery matches the specs of the OEM battery in my car. 90 Ah, reserve capacity 160 min, 850 CCA (close enough to the 900 CCA on my OEM battery).
I just got mine yesterday from Crappy Tire on sale for just $185. With free BMWLogger and a K+DCAN cable I'll install and register it myself. I'll take that extra $400 in savings and use it for brake pads and fluids for the track next summer
