I’ve tested a variety of CR2032 batteries in my AirTags, including both name brands and several Amazon “no name” options like LiCB, AmVolt, and CELEWELL. There’s actually a big difference in battery life and reliability depending on the brand you choose.

If you’re interested, I put together a detailed comparison of popular CR2032 brands (including Amazon Basics, Energizer, Panasonic, and more) with real-world test results and tips for getting the best value. You can check it out here: https://airtagbattery.org/best-batteries

Hope this helps you pick the right battery for your AirTag!
