New DPS 9000 3.6 volt

[KOT]

I am looking at the new DPS 9000 that ritz camera is advertising on their web site. It is a 3.6 volt instead of the 7.2 volt. Has anyone seen this and what doe you think? I have a Canon S410 that takes a 3.6v battery. I assume the 3.6 volt DPS is the one I should get?? In addition, I am really concerned about its compatabilityas the screw in hole in thebottom of my camera is offset and not in the middle. How long is the DPS??How far will it extend outside my camera sides....
