Unable to connect battery stickcam

had one outside in a shed for years and noticed it was not connected. Brought it inside, switched out the battery and still no connection. Did a router power cycle and still nothing. Deactivated it and place it in setup mode (manually and qr code) and absolutely nothing after getting the message it was in setup mode. No lights, no other signs of life. I even uninstalled the app, wipe phones system cache then reinstall the app - nothing. What is strange is I moved another working one from its location to the shed and checked it after placing it out there. it is now doing the exact same thing - no signs of life, even after bringing it back in. I did not deactivated it but I did other troubleshooting as I did with the first one.
