Motorola s9 battery dead how to replace it. for replacement is there it is just use and throw one only? please let me know

After googling the problem, I saw a couple of PDF documents that said that Motorola would replace or change the battery, but the links to the documents were outdated. At this site, they said the battery is non-replaceable: http://direct.motorola.com/ens/s9/Headset_Home.asp.

I found this site for support, and it looks like it might be worth a try:

It looks to me like the battery can be replaced, at the service level, but that normally it is a throwaway item at the consumer level. See if they can help you, but, of course, get the price first, and that will tell you whether to have it fixed or replaced. Good luck, and hope this helps.
