    Hey everybody,

    I have this machine now around 3 weeks (max. 4 weeks) and when I first got it I calibrated the battery (did it again couple days ago) and it is most the time on power pluged in, sometimes I took it out for a couple min only cause I was running around the house or took it downstairs to the studio. Anyway, this is the info iStats Pro give me:

    Battery:
    Health 98%
    Cycles: 6
    Charge: 99%
    Charged

    So why it say 98% health already? After I saw it I calibrated again and it went to 100% but only couple hours. And how come it dont charge to 100% anymore?

    its just the luck of the draw man. Some people get good batteries some get ok batteries. Mine happens to be one of the good ones but i did use my own style of charging though. For like the first 2 weeks i would use to about 20% left then fully recharge it just to get my cycle count up and excersice the battery. But as of late i leave it plugged in most of the time but atleast once a week i depleate it and fully charge it just to excersice it. Im still at 100% health to. So you should let the battery run down every once in a while and your battery will be ok.
