Many months ago prior to my receiving my S, I read a thread here discussing the effects on the battery of doing a Range charge. Someone who seemed to know what he was talking about, indicated that doing a Range charge was not a problem for the battery PROVIDED that the car was driven following the charge. Problems were only created if you left the battery with a Range charge for an extended period of time. So you shouldn't do a Range charge overnight and then just leave it for later use. The idea that Broder didn't do a Range charge because it would harm the battery seems to have gone unchallenged. Can we get technical clarification on this?
