    It's normal that it stops charging between 93-99%. This should answer most, if not all, of your battery questions:

    What app is it? What does System Profiler show as your battery condition?

    I would trust Mac OS X more than a 3rd party app. For battery specs, iStat Pro and iStat Menus are pretty reliable. Even coconutBattery has known issues.

    Your battery is fine. I would disregard the Battery Inspector report on cells. I can't find detailed stats on that battery model, but I believe it has 12 cells, not 3. If that's the case, the cell report in BI is bogus, anyway.

    The app is wrong, delete it as it is only giving you misleading information, you really dont need to worry too much at all about the battery in a newer Mac
