(This thread was closest to my query.)

The only place I could find the right kind of battery for my 2009 4.8 X5 this morning was WalMart. So I should not go this route because there could be an issue with coding and their battery might be deficient? I started at Sams but they didn't have H8 in stock and couldn't find the battery!

I have an appointment with the dealer Tuesday AM, but am not willing to pay $350 for coding.
