Is this battery toast?

[bradsdad]

I bought a parts-donor iBook G4. I needed a display screen for a 1.33Ghz 14" model, and found one with a busted logic board. The battery that came with it is stuck at 53% charged, does not charge further, and also will not power my iBook. System dies if on battery alone. Battery is known to the OS, it's listed in System Profiler, but seems frozen in that it won't take a charge and won't give any power out. Any ideas?

Yes, it's toast.
