how to charge airtag?

TLDR: AirTags are powered by a disposable CR2032 lithium coin battery that lasts about a year. They do not require charging; instead, users must replace the battery when it runs low.

Apple's AirTag utilizes a non-rechargeable CR2032 lithium coin battery, which is common in small electronic devices. The battery typically lasts around one year under normal usage, and users will receive a notification on their iPhone when it's time to replace it. To replace the battery, simply press down on the metal side, rotate the cover counterclockwise, remove the old battery, insert a new one with the positive side facing up, and replace the cover until it clicks.

It's crucial to handle CR2032 batteries safely, as they pose an ingestion hazard, especially to children. Additionally, not all CR2032 batteries are compatible with AirTags, so check for compatibility before purchasing. When disposing of old batteries, recycle them responsibly to protect the environment. By following these guidelines, users can ensure their AirTags remain functional and safe.
