I need one for 2000 BMW 5 Series. I've looked around and not really sure how to figure out which is compatible and which is not. I understand I need at least 70Ah and physical dimensions must be the same as original. Apart from there 2 criteria, what else is there to consider? I see many out there but not all compatible for some reason.
