Nope, no battery reconditioning software for newer Mac's (I think PowerBook G3 Series was the last model that could use one). The newer batteries in the new models of PowerBook's are supposed to be smarter, they cycle while being on AC between 95% and 100% charge to not be over-loaded. However after a while the battery gets confused and needs to be recallibrated, i.e. you totally depleate the battery so the computer goes to sleep by itself when the battery is empty, then you plug in the AC again and it should be showing correct time again.
