Dodging the iBook G4 battery-recall bullet

When I heard about Apple's notebook-computer battery recall, I figured it must be the new MacBook Pros or something equally new. I was suprised that the recall -- for potentially explosive batteries -- was for the iBook G4 and Powerbook G4. Here are the computers involved:

Affected ranges of battery serial number prefixes are as follows:

12-inch iBook G4, battery model: A1061
ZZ338 through ZZ427
3K429 through 3K611
6C510 through 6C626

12-inch PowerBook G4, battery model: A1079
ZZ411 through ZZ427
3K428 through 3K611

15-inch PowerBook G4, battery models: A1078 and A1148
3K425 through 3K601
6N530 through 6N551

The serial number can be located on most models by removing the battery and looking at its underside.

Additional information is available via Apple's Recall Hotline: (800) 275-2273

Since we have a 14-inch iBook G4, there appears to be no problem and hence no recall. But I'll be pulling the battery and checking the model number just the same. The battery never gets all that hot. The left side of the iBook, however, does get pretty warm at times -- I think that's where the CPU and other chips reside (not sure of this, though). The Powerbook 1400, whose battery can hold a 30-minute charge on a good day, never gets warm -- even its CPU area, which is just above the keyboard on the right, stays pretty cool. there's a very good heat sink over it. I saw all when I did the memory upgrade a few months back (probably the easiest upgrade I've done on any piece of electronic equipment in some time -- even easier than adding Airport Extreme to the iBook).
