I have a 2019 540 IX.

I purchased it at the end of the lease. I usually change my stock batteries in my owned cars every 4-5 years to avoid being stuck on the side of the road.

From my reading my car has 2 batteries. Can anyone tell me if they have replaced theirs and if it was a DIY job or do you need to do this at a dealer ?

Thanks
