After 67 cycles can my battery really still be at 100% health?

    Both iStat and coconutBattery report me having 100% battery health, the latter suggesting 5351 mAh capacity.

    So, have I done a great job conditioning my battery, or is something wrong in the software?

    I'm at 77 Cycles and at 100% health and my battery still lasts as long as it did when i first bought the computer.

    I have 330 cycles and it reports as still being at 100% health (though it dropped down to 99% the other day!) so yes, it's definitely plausible. :)

    I'll post mine when I get home but I think I'm on about 300 cycles with 100% health. I just tend to excercise the battery. I do a mixture of:

    100% -> c.0% -> 100%
    100% -> c.50% -> 100%

    Seems to work well.

    My battery is at 100% after 90 cycles; let's just hope it stays that way. ;)

    I maintain my battery by letting out the charge every second day, and calibrating it every month.

    My battery is at 95% of original capacity at 5 cycles. I just got a replacement under the extended battery warranty program, and I'm wondering if it may be a dud as well. Yesterday it was at 97%. Not to mention a supposedly new battery came with 5 cycle. Is that normal?

    Oh well, I think I've been obsessing way too much about my battery. But, man, they are pretty expensive, and I don't want to have to get a new one any time soon.

    chillout its 2%! your battery is probably trickle charging. laptop batteries are so smart these days that they actually run down a few percent and then charge up a few percent while fully charged so it isnt on 100% all the time.

    youve probably left in on charge for a while (which is perfectly fine btw because of trickle charging).

    totally, their batteries are pretty good and last for quite a while...I'm over 100 cycles and my health fluctuates between 99% and 100%

    I am at 84 cycles and still at 100%. My capacity is still above the original capacity. Original 5020 mah, and current 5382 mah.

    No problem on my MacBook (this is a replacement battery after one of the recalls):
