I have a new 12" Powerbook. The battery came fully charged, and Apple's instructions recommend that the battery be fully discharged (use the PB until it sleeps on its own) once, within the first week of purchase. I also bought a second batter (Apple brand), which was came uncharged. Does the "one time, use-until-discharged" rule also apply?

My PB (G3 FW, aka Pismo) said that this procedure was for calibration of the battery charge-state indicator software. Your manual might say something different. If the complete discharge is for calibration purposes, then you would have to perform that calibration for each battery that you own.
