I don't know about that, but if you have a battery tender that plugs into the cigarette lighter socket, you can do that, which is what I did on my 2003 S. The 2003S with the MOST (least) bus doesn't use a radio code though. If you disconnect power, the e-gas and windows have to relearn their positions though if I recall correctly. I've done it that way too and it wasn't a big deal. Also, I think the radio station pre-sets are not lost with power disconnected, but I'm not sure.

PS, best way to get the old battery out and put the new one in is to stand in the trunk!
