If you're new to AirTags, you might be wondering how to charge them. After all, there's no charging port, and they don't come with magnetic chargers like other Apple products. The good news is that AirTags run on standard CR2032 batteries, so you don't have to charge them. After about a year, when the battery runs low, you can easily replace the AirTag's battery yourself. In this article, we'll explain how AirTag batteries work, and teach you how to check and replace your AirTag's battery.
Things You Should Know
- AirTag batteries should last for about a year, though you may want to keep replacement batteries on hand in an emergency.
- You can check your AirTag's remaining battery percentage in the Find My app.
- AirTags use CR2032 batteries, which can be found at most stores that sell batteries.
