In your original write up under the section on using Rheingold you wrote
8) Rheingold then walks you through your options! You can simply register a new like-for-like battery, or you can change the battery capacity. Rheingold will prompt you to perform coding using ISTA-P!

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?
