AirTag battery replaced but still reads low even though battery doesn't have bitterant

Christiaans solution worked fine so thank you. But there is something odd here. I have 6 AirTags which I use in various pieces of luggage when I travel. Today I had to replace two batteries. The first AirTag went just fine. The second AirTag I had to follow Christiaans solution. Why the difference? Two batteries from the same pack. Same person me. Same iMac and same iPad searching and finding the AirTag. But replacing the batteries in the two AirTags not the same. Odd. Do AirTags come from different batches with subtly different electronics in them?

I have a slightly different issue - replaced the battery and on my iphone it now shows full but Find My on my Mac refuses to recognise the new battery and still shows almost empty. How do I force Find My on the Mac to refresh properly?

Restarting the app didn't do it. Can't see any "refresh" option in the app either.

Guiriman’s solution worked perfectly after unsuccessfully trying turning off and on Bluetooth, iPhone etc. As above issue was using Duracell and I presume their safety stickers leave enough residue to impair a proper electrical contact. Thanks for sharing

Easiest thing to do when replacing your batteries is to take the old battery out, wait 5 minutes, and then put the new battery in. The low battery message won’t be there if you do it that way. For some reason if you immediately replace the battery it still shows low (but I’m told over a period of time the battery status will update on its own). So again to avoid all of this, just wait 5 minutes before putting the new battery in.

Thanks for providing your solution! I'm sure it will help others who come across the same issue as you did.

I had the problem of the air tag showing low power after replacing the battery but solved it by wiping down new battery and case with a qtip and a small amount of alcohol

The airtags are so problematic - total pain. Will try this - thanks.

AirTag battery was replaced, still showing low on find my

Christian's solution worked for me: "The way I got rid of the 'low battery' label was to go to the Find My app and remove the item, then reactivate it:

1. Go to item in Find My
2. Swipe to the left on the item, then tap on the trashcan, tap on Remove.
3. Now, with the new battery in place, just reactivate the AirTag and relink it to your Apple ID."

I removed the little sticker on the negative side and rubbed both sides with a wetwipe for about a minute and it worked. The battery is duracell.

Worked. Thank you.

I had same experience with Duracell. They absolutely would not work in the AirTag.

i turned on Bluetooth, and it immediately showed full battery.

Happy to help and glad it worked for you.

These did not work for me.
