Replacing the battery in an AirTag is a simple process that can be completed in a few minutes. An AirTag is a small, coin-shaped tracking device that can be attached to items such as keys, backpacks, or luggage. The AirTag uses a replaceable CR2032 coin battery to power its Bluetooth and UWB (Ultra-Wideband) technology, which allows it to be tracked using the Find My app on Apple devices.
It’s important to change the battery in your AirTag when it runs low to ensure that it continues to function properly. A low battery can affect the AirTag’s ability to transmit its location, making it difficult to track your item. The AirTag will notify you when the battery is low through the Find My app or by emitting a sound.
