    I tried searching, but nothing came up so in turn:

    Currently my battery (and computer) is 7 weeks old. My battery capacity is designed for 6300mAh, but the day I got it it was at 6100mAh. I didn't complain, but I asked and they said this was normal--I guess not all batteries are perfect. However the capacity has not decreased much since, only to 6075mAh.

    I had pretty bad luck before with batteries with them dying at 30 cycles, but this time it's been good. So far it's at 65 cycles. When should I expect the battery to die at the rate I am going at?

    Hmm... I had a replacement battery just last week, so far it's done 3 cycles and dropped 3% to 97% Battery Capacity. I'm wondering is there something wrong with my Logicboard, this is happening with two different batteries. At the moment, I'm kinda wonder what's gonna happen after 100 cycles.

    I got my penryn mbp two weeks ago, and the battery capacity started at 98%. It's now at 96% after 8 cycles. Apple told me it was normal, but who knows.
