hi all, i dug up my girlfriend's 10gb 3rd gen ipod (with 4 control buttons above wheel), which she purchased used somewhere a while ago. it performs well enough, but the battery is sub par. i still need to time it, though. according to its tech specs, (http://support.apple.com/kb/SP99), battery life should be about 8 hours. i KNOW it is no where near that. i've noticed apple charges an 'arm-n-a-leg' for battery replacement, (http://www.apple.com/support/ipod/service/prices/#us), but i also found a site such as this one, (http://www.ipodbatterydepot.com/shopping/productdetails.asp?category1=&recordid=3). have many other diy-ers have success with third-party battery replacements? any and all thoughts welcomed!
