Find My AirTags

If you started using AirTags when they became available in April 2021, their batteries are well over a year old now and should need replacement soon.

Check them in the Find My app, and watch for notifications. They take a single CR2032 3V lithium battery, but avoid those with a bitter coat to discourage children from swallowing them. Instructions are at apple. co/3CdWJGD.
