Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your device.
To help you with this issue, may I ask:
1) The AGE of the device?
2) WHEN this issue first began?
3) Do you intend to replace the battery yourself (as a DIY project), or have someone do it for you?
Please use the REPLY box below.
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved?
I only ask because I have not seen any response for my original questions. But I did want to send the following links, for resources on where to get a battery kit AND the steps needed to replace the battery yourself - if that is what you want to do.
