This is very similar to the OEM one and I read that Exide makes the OEM batteries for BMW. Price is similar to the other brands at Advance Auto Parts and Auto Zone without coupons.

I installed that exact battery today. Pretty much the same battery down to the indentations. OE was rated @ 900 CCA, Exide is 850 CCA at 0 F. Wouldn't make any difference here in southeast TX. Both 90Ah, and 160 RC. OE was also an Exide.

Used ISTA to register it. Highly recommend it. I got it for $159 shipped from Rural King. It comes with free replacement for 4 years.
