Not working

My doorbell ring is 3 1/2 years old it stopped working recently so I plugged it in with my USB cable and make sure it’s fully charged battery, once I unplug the USB cable it does nothing, won’t even hard start, it’s dead. is there anything else I can do , because I tried everything, I spent at least a good two hours working on it

Hi @ Jim828. Since your Doorbell is not holding a charge after a few hours, I recommend reaching out to our support team at 1-800-656-1918 for further troubleshooting!
