At what mileage are you guys replacing them? I'm at 38K and still seams to have plenty of crank.

almost 39,000 miles now. Only 12.1 volt. drive it once a month might be the reason my battery is dying.

gotta get it on a trickle charger with so infrequent driving.

I talked to my service advisor about replacing mine at 4 years; she said it was too early if I didn't experience problems, but they do recommend doing it at 5 years.

Guys under which menu is the new battery 'registration'?

All I can find is 'Battery Adaptation' or something from memory under the engine section...is this the same thing?

this topic definitely will get attention if it really costs $600 when the battery needs replacement. I checked Autozone and it does show they carry AGM type batteries for the Z4

The ECU has to be told that a new battery is installed in the car. That is the "registration" part. You can install the battery and do the registration, but you ave to have the software and OBDII cable. It's very easy once you get the SW installed in your laptop.
