Vinny, I think you were just unfortunate! I just ran a search on Wikipedia for "Powerbook" and found the paragraph below:
== Product recall of PowerBook G4 units by Consumer Product Safety Commission ==
On May 20, 2005, the Consumer Product Safety Commission ordered a recall of some Apple PowerBook G4 batteries. The official CPSC recall notice states that an internal short can cause the battery cells to overheat, posing a fire hazard to consumers. Consumers should stop using recalled products immediately unless otherwise instructed. The defective batteries can be returned to Apple for replacement. Approximately 128,000 defective units were sold.
