I have a very lightly used battery in my macbook pro..
According to Istat it has 45 cycles, but the battery health is showing 65%.
I was wondering what could case this, i generally use my computer for desktop replaement, and i run them hard.
Any ideas?? Would Apple replace the battery under apple care??
Thanks in advance.

Did you calibrate the battery lately? If not, do so, your battery may have a bad reading.

But if it seriously is 65%, its a defective battery and Apple will replace it. -
Yeah. And while batterywear is common, that's somewhat extreme. Still, it happens and it's either the battery or the charging chip in the laptop.

I am not too worried, since i have bought an extra battery, but that is no reason to put up with a bad battery.
I had close to 300 cycles on my first battery (which ironically was defective and was replaced with this one) and it still had like 92 % or so battery health.
Hopefully caliberating will help (in process now) i am using parallels so it should die quickly.

Very Interesting , i am working on doing a calibiration, and the health has just jumped up to 96%
VERY ODD??

Not really. That's where it should be. And after you calibrated it jumped back up.

WTF.... it was working perfectly until about 10 mins ago, it just had 39% and then all of a sudden a warning that i am on reserve power came on, and the health dropped back down to 67% ...
I hope this is a part of the process, otherwise i am just being anal, and pretty soon you guys will get annoyed with me. -

I think you should complete the entire calibration process before jumping to conclusions.
