Apple issued a major battery recall, due to the fact that, apparently, the same batteries that have wreaked havoc among Dell users, are also used in the iBook G4 and the PowerBook G4 (12" and 15").

I recently bought a new battery, because the one that originally came with my PowerBook was becoming unreliable, causing the machine to quit without sleeping or shutting down properly. However, it seems this battery is eligible for replacement, so within 6 weeks I'll be the proud owner of two batteries. Which is excellent when I have to travel long distances. I also checked the new battery, but its serial number falls outside of the range given by Apple as the danger zone.
