From this and reading a bunch of differing opinions I came to my probably wrong conclusion.
Is it that you can change the capacity or type without changing the VO in ISTA/D and still have the correct charging regimen? If true, is the downside that if a dealer does some updates on your car it will revert back to the original battery capacity and type?

I may have been wrong in the write up. I think rheingold just brings you to a new tab/procedure... Not a different app. I also do not believe it changes the $vo so you'd be correct the setting would be set back to factory defaults with dealer programming. The dealer is not likely to provide any programming though... It takes a lot of time. The only thing they really do is update the DME when people have driveablity issues and that won't affect the battery coding.
