Artale, in case you didn't know but when the ASR is out of energy saving mode the battery supply is completely disconnected from the wall - of course it's not charging either but with 100hrs or so of reserve I've haven't found that to be a problem. In other words, I wouldn't bother changing the battery supply cable unless your in energy savings mode most of the time ;) I have my unit set to never enter energy mode (set to 0 from the factory 35).
