    Ok what should the NORMAL, battery health be for a 13" MBP bought over the 2010 summer? Mine is 96% is that ok?

    La lala.

    96% sounds about right, have you calibrated it properly?

    My MBP had 91% once and now is back at 99%.

    About two weeks after I purchased my MBP I installed Coconut and noticed that my max battery capacity was 97%, with 32 cycles, and my machine was approximately 4 months old. I thought it was a rip but maybe it is just normal.

    I have 29 loads and 99% health according to coconut battery. Perhaps recalibrate?

    This is the 7th thread you've started on battery issues. I highly encourage you to read the Apple Notebook Battery FAQ that spinnerlys directed you to back in July. It will answer all your battery charging/calibration/health questions, if you take the time to read it. There's no need to create duplicate/redundant threads when the answers have already been provided to you.

    I've read the information about calibrating the battery and have 2 questions. First the info I read:

    In step 4, I believe the low battery starts at 19%. Should I keep on running it until the battery level is in the single digits or it doesn't matter?

    In step 5, does it matter if the screen is open or closed?

    It doesn't matter... just save your work before it gets too low. Or just do something that doesn't require saving, like web browsing.
    It doesn't matter.

    Thank you very much. I've been reading the support info about battery life from the links provided and it's been incredibly helpful. I will be much more diligent about calibrating. Can you calibrate too often, like weekly?

    Well, calibrating too frequently puts cycles on your battery needlessly. Calibrating once every month or so is all you need.
