I've tried all of them - different batteries (although they only last about 30 sec each), no battery, PRAM reset and PMU resets. Plugged in overnight, cold boot, etc.
I'm positive its an OS 9 issue. Its happened before - I installed OS 8.6 onto a USB drive via an iMac and used it to boot an iBook and got the same problems.... also had that problem with an iBook clamshell... Both times, reinstalling from OS 9 solved it.

Did you consider to start with extensions disabled? Some very old PBs are also known not to boot with dead or w/o batterie. Probably an internal backup batterie has to be replaced. The reinstallation might have fixed batterie issues because of the charge duration that comes with a System installation.
