Welcome to Bimmerfest! I've moved your posts to their own thread instead of being piggybacked on an existing topic. Could your battery be bad?

I changed three new batteries and all of them did the same problem .I think it s not the problem the battery.I think somewhere is losing the electricity but where I don t know

Best thing to do when you're unable to discover the problem yourself is take it in for service.

It is the alternator. Just had mine replaced. It is 2.7 hours of labor.
