Steve,

I believe you are experiencing the normal behaviour of the charging circuitry that has been used on PowerBooks for a number of years now. For reference, you may want to refer to Apple's Knowledge Base Document 8344, "PowerBook G4: Battery Does Not Show Full Charge in Mac OS X":

The document refers to OS X, but the same behaviour should also be seen in earlier versions of the Mac OS.

Hope this helps,
