I think I need to replace my battery in my 750iL (not Li) it has the V12 engine I need to know if there are 2 batteries (double stacked) or just one. When I look at the battery bay in the trunk it appears to be 1 stacked on top of the other. According to the local BMW dealer there is no 2 battery system. I am very confused. I left the lights on in my car in the heat and on the way home my battery light came on and other warning lights came on like a Christmas tree. Friends in my BMW forum are pretty confident I have a week cell as that is the indication when said lights start coming on. So is it a 2 battery system or one big one? Thanks.

It is a two battery system and I have no idea why the BMW dealer would give you the wrong information, maybe they are just confused (or stupid. Did I say that?) I recommend shopping the price around, especially considering the quality of the BMW batteries these days. The Costco batteries are quite good, I have bought several of them and had no issues with their quality.

I figured that. I think the top part just needs to be replaced so it looks like I will be purchasing the 5495R. I will keep you all posted.
