There are a couple discussions dancing around the 12 volt system in Roadsters:

However, I couldn't find a lot of specifics on the 12 volt battery.
1) Is it just an AGM battery?
2) How/when is it charged?
3) Can anyone categorically state which systems it drives and/or acts as a buffer on?
4) Has anyone had it fail? If so, what happens?
