Strange white macbook battery issues

Ok, I've had about enough out of my 2.16Ghz GMA 950 white macbook. Everytime I leave it sleeping and the battery in for an extended period of time, draining the battery completely, the battery just dies. It has done this to two so far. And I'm not just talking about the common x in over the battery issue. I've left it with the magsafe in for hours and reset the SMC on both occasions, and tried the battery in several other macbooks. I get a "(Not Charging)" icon in the menu bar, and in the pull-down menu it says "Condition: Replace Now" /!\. Has anyone else had this issue? Is my macbook just killing batteries or is there some way to revive them? Any help would be appreciated. Thanks.
