My AirTag doesn’t work after changing batteries

We bought these AirTags (pack of 4) 3 years ago, put them in our luggage and backpack and they worked fine. My backpack and large suitcase reported a low battery, so I bought new Energizer batteries to swap out the batteries. I had no problem with my large suitcase but my backpack still showed a low battery even after swapping out to all new batteries that were in the package. I restarted my phone, checked the WiFi, checked the Bluetooth, even cleaned the inside of the AirTag and reset the AirTag but can’t get it working again. I even uninstalled it from ‘Find My’ app and try to reconnect it, but it didn’t. What can I do to get it working properly again?

On the problematic AirTag, when you replaced the battery and pressed down on the tag's battery cover, did it emit a beep (even before you rotated the cover to close it?)

If it doesn't then the issue is either with the replacement battery or the tag itself. Not to doubt you, but did you double-check to make sure that these Energizer batteries do not have a bitterant coating? Just trying to rule out that it may be the battery.
