Any battery that matches or exceeds these specs will do. If it differs significantly in the type (AGM) or capacity (80Ah) it will need to be coded as well as registered, but that's only a 10min job instead of a 5min job.
Of the 2 BMWs in my household, I've just replaced the original battery in one after 11 years and 105k miles. The other is starting to get weak, but no issues yet at 13 years and 135k miles. Brand snobbery does count for something. Buy cheap, buy twice, for most things!

Buy cheap with a 4 year warranty if it fails at 4 1/2 years throw it away and buy another and still costs you less than a big brand battery. How much warranty do you get wirh a snob brand battery?
