You must register it for best service life. It will work without registration but will not last as long and may cause other problems. Registration will demand AH capacity as that is the controlling parameter for proper charging.

You can replace it yourself and then drive to the dealer or a good independant who can register the new battery for you and also indicate the capacity (e.g 105ah) if you use a new battery with a different capacity. You can also get an app like the Carly app which will allow you to do both functions.

Do check at what amp-hours this battery is rated. From what I can see it's in the 90-95 Ah range. So, if your OEM one was 105 Ah you need to have someone first do a conversion in ISTA or use e-Sys (or a coding tool) to change the capacity *before* registering (different operation). Ideally, you should buy a 105 Ah AGM battery, though 95 Ah would be fine - in 2010/2011 95 was the default battery for Fxx. With 105 Ah you would only need to register.

Thank you all

I really appreciate for the informative response - I returned the battery from AutoZone as I did not install it yet, and went and got one from BMW 105Ah (The difference was just a few dollars in price (less than $15)) I did register it using Ista+.

JeffDunes - I did ask the dealer if I put in the battery myself will they register it for me, thay wanted $180 just for that - I told them "No thank you".

Thank you all
