iBook G4 battery charging, from green to orange, back and forth

So, iBook G4 1.42GHz is now up and running with Leopard. Swapped disk from another machine so I had to disassemble two iBooks (why are they built the way they are?). Machine works well except for the fact that there's something strange going on with the battery as the charging light shifts back and forth between green and orange. From the system info I can see that the battery does get more charge, slowly but still.

The battery has over 600 load cycles so is it just too old? System info claims that the battery condition is "Good". The machine works with the battery and also with only the charger. I had to detach the DC-IN board in the disassembly process so of course I might have damaged something.

EDIT: Well, with this case it was just too old:

Green light means that it is charged and the orange light means that it is charging.... Prevents overcharging

Yes I know what those colors mean but in this case they cycle back and forth, also when I check the system info it shows that the battery is not full. Maximum charge for this battery is 1306 mAh and at the moment it is charged at 934 mAh. I hope the battery is just tool old and the DC-IN board is fine, according to that other case I linked that might be the case, also, over 600 load cycles is a lot of usage.

If it cycles back and forth non stop it is most likely the battery.Like you said 600 cylcles is a lot of usage and it no doubt lost its charging capacity over time.If possible I would get a battery asap.

This.

Apple recommends battery replacement around 400 cycles. Not that I do everything (or anything) that Apple recommends, but it is a guideline on battery life.

Yes, I left the machine with charger connected for some time and apparently after it finally had recharged it stopped that shifting and remained green. Over 600 charges is, as said, very much and even without these kind of weird symptoms it is natural that the battery is not in its best shape, which it isn't since it holds charge for about 30-45min.

Longer than two of my batteries.
One battery I have, I've got about two or three minutes after opening the lid on my laptop before the Mac goes to sleep.

Same thing happened to me

Hey,

Also, this just happened with my PB G4 DLSD 1.67 - I almost freaked when I saw the charge light going from green to amber vice versa and realized my battery has almost 390 cycles left.

Time for a new battery!
