-- Posted by my name sucks at 8:24 am on July 12, 2008 can you replace battery's on them? the battery on mine won't charge but the rest of its fine... any idea what kinda battery's it is? -- Posted by gnr90 at 8:28 am on July 12, 2008 you probably have to have them do it... -- Posted by Darkane at 8:28 am on July 12, 2008 I don't think they're removable. Unless you crack open the case and see what's inside but that'll void alot of stuff. -- Posted by nikki at 11:13 am on July 13, 2008 Get the battery replaced, but you'll have to do it through Zen.
