As in thread, I noticed in CoconutBattery and in iStatNano widget that my battery is losing capacity, yesterday I had 96% now I see 94%, I've got my MacBook since May and it has 59 cycles yet. I think that it shouldn't lose capacity now, ok, later but now is to fast, do you think so? Is there any solution to increase this capacity? I've got MB Unibody 2GHz, Late 2008, but I bought it in May 2009 "as new"..

Congratulations, your battery is obeying the laws of physics and chemistry. Batteries lose capacity over time, and day-to-day bookkeeping is ultimately meaningless. If your battery dips under 80% capacity by next May OR before it hits 300 cycles, you've got a case for claiming your battery as "defective."
 
I calibrated it week ago by:

- Charging up to 100% than stay on AC Adapter at least 5h
- Let it working to be fully discharged than wait 5-6h
- Than just charged it to 100% and that's all what I did

OK I'll try to do calibration again :).
 
This doesn't look normal, i've got 100% health and 86 cycles over 8 months, try calling apple explain your situation see what they do about it, your really close to the 80% with only 60 cycles, that is considered a defect for me.

And i've only calibrated once, that was when i bought the macbook.
 
I will try to calibrate one more time, if it will be useless I will call Apple Support Line :).
 
OK I fully charged it before night and turned off for night (fully charged) now, in the morning I started my MB and it has 99%, so I will discharge it and than not use for at least 5h and than plug in power adapter and fully charge, yeah?

Just use the computer! Those utilities aren't the most accurate and your battery will depelte anyway. Stop worrying about it already.

Hah... before calibration my battery health suddenly increased to 93% than after calibration decreased to 91% - funny, now I see that those apps sucks.
