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?
