I read about OWC's iPod battery upgrade a couple of weeks ago on Maccentral. I ordered it almost immediately, as my 2.5-year old iPod has a battery that lasts no more than 2.5 hours on a fresh charge. Got this battery a couple of days ago in the mail, and I installed it that night. Now my iPod's dead. I put the original battery back in there, but no difference. If the iPod shows anything at all, it's a language menu with a lock icon in the upper left. I can not select anything. The buttons and scroll-wheel do nothing. Then my screen goes clear. All the button-pressing in the world does not change this. I can charge my iPod. I can watch the little battery-power-level bars in the upper right go through their little progress animation thing. Then when it's fully charged, I get the check mark and no battery meter animation. I remove the iPod, only to get the language menu and a blank screen. I wrote OWC's tech support, which was supposed to get back to me within 24 hours (or "most likely" within 24 hours). That was about 2 nights ago. I have yet to get anything but an automated message from those guys. Unless I did something wrong that I am completely unaware of, performing this transplant somehow ruined my iPod. Let this be a warning to anyone considering a purchase of it (although I am certainly open to tech support suggestions).
