    My Unibody MBP battery's full charge capacity is 4531 (which is "good"). I calibrated it the day I got it. Is that in the low range of "good"?

    My Classic MBP has a replacement batt that is about 3-4 months old. Its full charge capacity is over 5k, and it has not been calibrated since I got it.

    Anyway, no real complaint here as long as the overall health is good.

    Just curious to know if my Unibody MBP's full charge capacity is ~average for brand new?? What's your new Unibody MBP's full charge capacity?

    The new unibody mbp's actually have smaller batteries so it makes perfect sense that your new mbp has less capacity than your old mbp.

    You'll have to do a search to see what the stated capacity for the new macbook pro's battery is and then compare it to that.

    The newer unibody MBP has a lower-capacity battery. While the old one has 5600mAh @ 100% health, the new one has 4700mAh @ 100% health. So the "good" I believe is measured relatively against the initial capacity.

    It started off at 100% when I first got it, It dropped to 98% 2 nights ago. I calibrated it and now it's at 102% :p. Looks like I got a good one :)

    Realistically though. 4691/4700 is 99.809%. I think your program is reading the initial power wrongly as 4600mAh. Awww... dammit... As I've said before... we need Tony Stark's arc reactor schematics to deploy mass market in notebooks. :p

    The original capacity of the batteries is 4600 mAh, not 4700 mAh. Actually, its 4630 mAh, but who's counting. :p

    50Wh / 10.8 V = 4.63 Ah
    4.63 Ah = 4630 mAh

    PS: My current battery capacity is 4720 mAh, and it's been as high as 4803 mAh. All I do is use it normally. When I first opened the computer it was at 4580 mAh. I guess I just got a good battery. :D
