    My powerbook g4 does have an odd problem. it takes about 3 hours to charge to full capacity and then after it reaches about 95 percent battery completely drops to zero.

    i ordered a new battery as it is the original apple battery but is there anything else possibly causing it?

    Is this an original battery? I've had a few iBooks with a almost dead battery and takes a long time to charge and the capacity it holds isn't much more than 10 minutes.

    The original battery in my TiBook acted exactly as you've described. A new battery fixed the problem.

    This problem has occurred to me with my iBook G3 before. What is happening is simply the result of age. The battery in your TiBook is made up of multiple battery cells. Your TiBook assumes that all of these cells are at least in working condition, which leads us to the problem. There is no sensor that tells your TiBook one (or multiple) cells are dead, so when your TiBook gets to 95%, and let's say uses one cells, it suddenly realizes that the rest of them are dead and/or nearly empty, panics, and shuts the computer down. Replacing the battery is about all you can do. At this point in time, I do not know of any applications for calibration that can help you.

    As I said, my TiBook was acting as you describe, and after a new battery reliably runs 3+ hours.

    Just be sure you do a battery calibration on the new battery so that you get accurate times.

    Whoops! I messed up a bit on that one, but my statement still stands true for an Aluminium Powerbook G4 and truly any laptop in general.
