    I just used coconut battey to check my stats and found out my battery had a 55 cycle count and the battery capacity is at 90 percent. I think there is something wrong with the battey. My friend gave my this battery brand new a couple of months ago, I have black MacBook Core Duo and have been using this laptop for almost 5 years and it's still in perfect condition. Should I be worried about this battery?

    Try calibrating it before getting worried. I doubt there's anything wrong with the battery, it's probably just not reporting correctly and needs to be calibrated.

    Same thing happened to me, my battery health was at 97%, then I calibrated the battery and it went down to 84%. I had 50 charge cycles.

    That means the battery health was already at 84%, but had been erroneously reported as 97%, until you corrected it by calibrating.

    Read the Battery FAQ I posted earlier. It contains the exact steps for calibration.

    Mine is at around 91% with approximately 52 cycles. It's probably normal.

    Mine started out brand-new at 97%, and now at 95 cycles is 87%. It has been carefully calibrated several times following the recommended procedures. I generally leave it on sleep, don't turn it off, and keep the electrons flowing, so to speak. There was some guy that posted not too long ago that was above 97% after 300 or more cycles. I think some batteries are just better than others.

    Some definitely are. A bought a new Macbook a year ago. In that time, I've put around 150 cycles on it and I'm at 88%. My last Macbook had flitted between 99% and 100% health after 275 cycles and 2 or 3 years of ownership. Both were regularly calibrated.

    thanks for bringing this up. It stimulated me to check out my own MBP's battery life. Looks like I've got one of the good batteries. I conditioned the battery when I first bought my MBP, and condition it each month.

    the app battery health reports the same as coconutbattery 2.7
