ipod battery replacement

Battery replacement iPod?
I have an ipod nano 4gig genraration one, I bought a while ago, I remember when. My battery life seems last long, I can listen to three hours of music before it hits the battery turns red. I absolutely hate it! IM planning to send the iPod program Battery Replacement. I do not think he has the warranty. "I can send? what they are doing about it? Has anyone tried it?
i havent been given, but you can change the battery without any guarantees, I know that much. costs a little money too. Also, you can replace, but I do recamend can Yur broken iPod, and this would really suck!
