    My Macbook Pro 13" is only 4 months old, however coconut battery is reporting that the battery is already at only 89% health after 75 loadcycles, just wondering if I should be getting hold of apple for a replacement battery?

    How do you do that? My battery is at 25 load cycles, 99% capacity, but it's supposed to last 8 hours and I'm getting about 1:30 out of it.

    Do a search on battery calibration. There are countless threads with the necessary info in them. Have you heard of Mroogle? Google it, it is very useful.
    :D
