Same problem - but SOLVED:
I was ready to return my 2nd battery to NewTech when I decided to boot up from my Panther disc and install it (this OS 9.2 Clamshell has no firewire so it won't go to Tiger). Once it booted, the charger plug turned orange, it recognized the battery and it began charging!
I have another battery that half-charges, so I didn't think it was my hardware at fault.
Somehow temporarily starting with another system allowed the computer to recognize and charge the battery. I had upgraded from 9.0 and done a hardware upgrade before I bought the battery.
Come to find out, the Clamshell, not having a PRAM battery, saves the last bit of juice in the battery for it's own settings. I'd done all the other acrobatics but I hadn't left it without a battery overnight - that might have worked as well.
Good luck, it's still a handy-dandy notepad/typewriter/journal.
