    Hey Guys,

    My battery which was less than 9 months old crapped out on me so apple sent me a new one. Now with 4 load cycles and basically being used in the mac for 2 weeks. The bat is now down to 95% capacity. Should i be worried? Cause this is losing about 5% bat capacity within two weeks and 4 load cycles. By the way im checking this using Coconut Battery.

    Try recalibrating your battery

    Battery Calibration
    1. Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
    2. Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
    3. Disconnect the power adapter with the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, you will see the low battery warning dialog on the screen.
    4. Continue to keep your computer on until it goes to sleep. Save all your work and close all applications when the battery gets very low, before the computer goes to sleep.
    5. Turn off the computer or allow it to sleep for five hours or more.
    6. Connect the power adapter and leave it connected until the battery is fully charged again.
