I've Been Traveling With an Apple AirTag for Years-Here's What Everyone Gets Wrong When Using Them

"AirTags only work if they have enough battery power, which only lasts up to one year. Instead of buying a new AirTag for $29 when the battery dies, you can simply replace the battery. But you'll need the right type: a CR2032 3-volt lithium coin battery to be exact."

"Many CR2032 batteries come with a bitter coating to prevent ingestion. Although this is a helpful safety protocol to protect children and pets, the coating can interfere with the AirTag's battery contact receptors and not work. To make sure you're buying batteries that work with AirTags, look for ones that say compatible with Apple AirTag on the packaging."

"An AirTag battery lasts about a year, but that can vary depending on how often you use your device. Apple will send a notification to your iPhone and warn you on the Find My app when your AirTag battery is starting to die. You can also check the battery life at any time if you've connected your AirTag within the app."

AirTags are valuable travel accessories that help locate lost luggage through remote GPS tracking. However, their batteries last only about one year, requiring replacement. Rather than purchasing new AirTags at $29 each, users can replace the battery with a CR2032 3-volt lithium coin battery, potentially saving over $100 for multiple devices. When selecting replacement batteries, it is crucial to choose ones explicitly marked as compatible with Apple AirTag, as many CR2032 batteries have bitter coatings that can interfere with the device's battery contacts. Apple notifies users through the Find My app when battery levels are low, allowing timely replacement.
