    Hey there forum!
    Last week I've purchased my very first Mac, and it's just great ^^

    Now, after using it for a week, CoconutBattery says my battery capacity is at 94%, which seems troublesome to me. Also, it says my MacBook Pro is 3 months old o_O

    Would calibrating the battery deal with this problem?

    It's normal for your battery capacity to fluctuate up and down over time. If you search the forum with MRoogle, you'll find dozens of threads on this. You have nothing to worry about. You should, however, calibrate your battery, as Apple recommends.

    The age of your Mac is determined by its manufacture date, not the date you bought it.

    Battery capacity reporting isn't that accurate anyways. Calibrate it if you want, but it's nothing to worry about.

    Didn't know that, pretty simple logic actually.

    Not to worry it is then, thanks! =)

    Don't worry about it. Calibrate it, and then use good battery health techniques, like not charging it unless the battery is at under 40% capacity, and making sure you calibrate once a month.
