Hey MacRumors, I've got a late 2009 MacBook, and after 231 cycles my battery is at 82% health. Aren't the batteries supposed to be at 80% after 500 cycles? If I take it to the Apple store, will they replace my battery? I use the hell out of my computer, but a warranty is a warranty. Also, if they do, will the bitch that I have 4GB of non-Apple RAM and a non-Apple hard drive installed? Thanks!
