Sigh….
My second MacBook Pro Battery is sucking just like my first one. At about 50 power cycles the battery”s life falls from 90% to 80%. This is ridiculous. I have had Windows based laptops with batteries there were a lot better then the MacBook Pro batteries that I have had so far. Right now it is sitting at 82%. From reading the Apple forums and othter sites, others have the same problem. Does Apple do anything about this? No, not really. They say it is normal. I say, 50 or so power cylces in a year (once a month) should be enough to maintain a health battery (Apple even says to do this), but as you can see it is not working.
I give the Apple MacBook Pro laptop batterys a 1 out of 5. Very poor quality when compared to other laptops/batteries that I have used.
