    Just wanted to know what is the typical full charge capacity for a brand new MBP 15" (mid 2009).

    Mine says: 6433mAh

    is this ok? or a bit low for a brand new MBP?

    I got my computer replaced last week, and I feel that the battery life on this one is slightly less than the previous one. Maybe i'm just being paranoid.

    I've got a refurbished 15" MBP that arrived on Dec. 1st. Since then, according to the "Battery Health Monitor" app, I've had 56 charge cycles (sometimes two a day, evidently) and the current capacity is 102% - 6628mAh. Original capacity of 6500mAh.

    Calibrated a couple of times. I seem to remember, before I calibrated the first time, it was a bit lower than I thought. After you've calibrated, I'd imagine it'll be around the 6500mAh mark.

    I'm more worried about the fact that it says I've apparently used up 14% of my charge cycles already despite having a higher-than-normal capacity when fully-charged! :eek: Might calibrate it again overnight.

    Cycle count: 4
    Condition: Normal
