@itaplus3,Yvette, Use the 1st link for Fitbit charging problems/solutions. Sounds like you may have a faulty battery. If under warranty return for repair/ replacement /refund. If not under warranty and you would like to attempt battery change use link below. If your model differ's comment back and I will see if I can find you the battery changing guide. 3rd link is to a replacement battery. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
