i'm at a loss,  I have an iBook G4 that seems to not like my replacement battery.  Is there a battery charging program that will read the status of the battery? Although I have tried to calibrate the battery, it seems to not charge.  The battery charger ring is amber, and when I look at the system profiler, it says the battery is not charging, and never goes to green.  When I place my original battery in, it will show charging status, and after 10 minutes the charging ring will go from amber to green and never get more than 6 percent charging at a time. When I remove the battery from the notebook, it cycles the charging system to charge, then quit.  I have replaced the battery charger but that seems to not help.  Have I got two dud batteries?  The system profiler says the batteries are good as well.  Any assistance with this would be greatly appreciated.

    Do you have someone you can borrow another battery from and try that? I seem to remember a charging program awhile that did deep reconditioning of batterries. I believe they do exist.

    When the charger ring is amber this indicates its charging the battery. If you look at the top right battery meter, does it say its not charging and show or show an X?


    Is this an original Apple replacement battery of a third party? Some third party batteries made in China are not very good replacements. I've known them to be dud.

    It can only be one of two thing. 1. The battery is faulty and hence the reason for it not charging  2. Their is a problem with the DC in-board or charging circuit.


    The only real why to test the charging circuit or DC in-board is by using another known working battery.

    If someone was to give me a PowerBook with the same fault as yours to fix, I would first reset the PMU  and then try testing the PowerBook's battery with one I know is fine. If all test fail, then it has to be a problem with the PowerBook's circuit board, either the charging circuit or DC in-board.


    Three months is bad for a replacement battery, however this is influence by the brand of battery and the overall quality. Personally I tend to stick to Apple original or 2Power brands.
