We have found that due to the way the Duracell batteries are shaped, they are unable to power some scales properly. We are working to fix the issue in our scales to resolve this problem, but we've found that most of the time, just switching to a different brand of battery resolves the problem and gets the scale working again. Would it be possible for you to try a different brand of battery and see if that resolves the issue? If it doesn't we'll be happy to help with a replacement.
