Apple's AirTag, designed to track items, uses a replaceable CR2032 battery. Unlike rechargeable trackers, the AirTag relies on a coin cell, typically lasting about a year. When the battery runs low, your iPhone will notify you. Replacing it is straightforward, taking only a few minutes and requiring no tools, making maintenance simple for users.

The replacement process involves pressing and rotating the back cover, removing the old battery, and inserting a new one with the positive side up. The Find My app also displays a low battery warning. Ensuring the battery is correctly oriented is vital if the AirTag doesn't make a sound after replacement. This ease of maintenance is a key feature.

Most AirTag batteries last around a year under normal use. Apple provides warnings before complete depletion. Users should dispose of used batteries responsibly through recycling programs. This user-friendly design helps keep your belongings tracked without the hassle of frequent charging or complex setup procedures.

This simple battery replacement process underscores Apple's focus on user-friendliness. The wide availability of CR2032 batteries ensures minimal downtime. This design choice sets the AirTag apart, making it a convenient and practical tool for everyday use, and a solid competitor in the crowded item tracker market.
