    I've just installed coconut battery on my 2010 MacBook Pro, it was delivered last wednesday. It shows 3 battery cycles which would seem about right, but the capacity is now 95% of its original.

    Is this normal?

    Have you calibrated it yet?
    www.apple.com/batteries/notebooks.html

    Also MRoogle will give you dozens of threads, thousand and more I think, about that same issue.

    Btw, battery health fluctuates, I got to 93% once and now it is 99% again.

    To be honest, I hadn't let it run down to nothing and had just found that link on Apples site before you replied! I'm going to give that a go now.

    Thanks for your response :)

    Are you in some way not sober? Or is your keyboard, spell check and display broken?

    I often see my battery at 98% rather than 100%, and I calibrated as soon as I got it. I'd be worried if the battery were down to 90% by next week, but otherwise I don't think it's anything to be concerned by.

    My money's on impaired. Avoid texting any friends, Facebook, and online shopping until you've slept on it and had a half-dozen cups of coffee and some aspirin to clear up that splitting headache.

    I just read you attached link didn't find clear info on Ideal Charging and discharging, but I was wonderin if it's best to plug it in whenever possible and discharge and recharge once a month like the link recommends or if it's best to discharge you computer fully and then recharge and repeat to "keep the juices flowin"???

    I tend to use it everyday and am by an outlet 90% of the time.... I just don't wanna diminish the life of my battery by constantly plugging it in or vise versa....

    Any info would help... thanks

    Leaving the plug in doesn't damage modern batteries, a calibration once in a while does do some good. If you use MRoogle, you'll find hundreds of threads about this.

    I use my Apple notebooks with a power plug most of the time, and once a week I use it on battery. Sometimes I even use it more on battery than on the plug. I still have good battery health after 100 and 200 cycles (95 t0 99%).

    Personally, I'd trust Apple to know a thing or two about how their computers work.

    Thanks for your help and advice!
