You could try resetting the PMU (Power Management Unit) which, among other things, controls...
...you've guessed it, Power Management.
To do this:
1. If the iBook is on, turn it off.
2. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
3. Wait 5 seconds.
4. Press the Power button to restart the iBook.
It's not going to magically revitalise your battery, but it may sort out the mis-reading problem and at least enable you to know how much ooomph you have left.
In case you don't already do so, it's also a good idea to disconnect the charger from the mains when not in use, this allows the charger's own internal circuitry to reset itself.
Two years for a battery is within the norms for replacement, how many charge cycles have you done?
Best of luck,
ibook G4 1GHz, 768mb; iMac 17" G4:768mb (10.3.9) Mac OS X (10.4.6) Belkin WiFi F5D7632
