Hello all. Newbie here. I have a 2000 Z3. I recently had AAA put in a new battery. Since then I have had a lot of trouble with the battery losing charge after a few days of non usage. I had the battery checked and it is good. I then read some BMW's have to have a new battery "registered" to the car. Is that something I need to do on a 2000 Z2? Thanks in advance.
