I replace the CR3032 battery in 4 Apple Airtags with Duracell batteries. No sound, no pairing. Next deleted the 4 airtags from FindMy and tried to readd - same - next replaced with Ever Ready. Sound oK but can't find in Find My
After replacing batteries in 4 AirTags with Ever Ready batteries and all 4 make the sound when inserting batteries, none of the 4 are found in Find My. I had deleted the 4 Air Tags in Find My when I had problems replacing the batteries with Duracell batteries. None made the sound when the Duracell batteries were inserted. So, I'm stumped - all 4 have Ever Ready batteries, all 4 make the sound when the batteries were inserted, cover put back on all 4 correctly. Find My is just "Searching for AirTag"!
