Ok the battery wasn't that great but it's gone from giving me a 2 hour charge to only lasting 30 minutes or so...
It's ok up to about 65% then it just drops to 3% then 0% . I tried calibrating it but that changed nothing.
Is this the end, as my battery gone to the big Apple graveyard in the sky?

They do that. It might last for a few months, it might die tomorrow. But its dying.

from previous experience, that's what it looks like to me

Depends which generation of PowerBook.
If it's a G4 machine, then yes, it's almost certainly moribund.
If it's a G3 then go get the PowerBook G3 Battery Reset app. from Apple, and use it to reset the battery's internal electronics (often worked).
If it's even older and you've got a NiCad battery, let the battery discharge completely, then take it out and connect a torch bulb across the terminals. Leave it for several hours to flatten the battery completely then re-charge.

Yes.
How long have you been using it (how many years?)

Hi !
It's a used G4 667, I've only had it a couple of months but I have no idea how old the battery is.... I'm guessing that it could be the one that came with the machine ..

15" TiBook same as mine, then? Lovely machines...
As far as I know, my battery is still okay, but it will depend on how it's been used. If the previous owner has been using it on battery a lot, and discharging it pretty thoroughly before putting it back on charge [1] it will be much more knackered than if (like mine) it has been kept on charge day and night whenever it was at home. Mind you, for all I know mine could fall over tomorrow...
[1] This used to be the way to handle NiCD (ugh) batteries. You had to discharge them fully each time, otherwise they would develop a 'memory' effect and subsequently wouldn't discharge any further. But 667 TiBooks, like almost all modern devices, have NiMH batteries which have no memory effect; the limitation on their life is the number of charge/discharge cycles that they go through, and the NiCD technique is totally counter-productive in their case. Best is to leave the NiMH batteries on charge so they stay topped up. But a lot of people are still grasping the wrong end of the stick and killing their batteries with 'kindness'...
What happens when you remove your battery and try the little lights which should give you an idea of what state the battery thinks it's in?

Yip, that's the fella :-)

At the moment I've got one flashing light but it does give 4 lights when it's fully charged ...
