Apple Cuts 2nd-Gen AirTag Price 21% to Record Low

Q: Why might buying the wrong replacement battery render your newly discounted 2nd-gen Apple AirTag completely useless?

Because the AirTag has no rechargeable backup and depends entirely on a compatible CR2032 coin cell, the wrong replacement battery can leave it unable to power on at all. Apple specifies a 3-volt CR2032 lithium battery. Using a different size, such as a CR2025 or CR2016, is not a reliable substitute and may fail to make proper contact or provide stable power. Even some CR2032 batteries can cause trouble: Apple and other reports note that certain bitterant-coated models, including some Duracell versions, may not seat correctly or make full electrical contact inside an AirTag. If that happens, the tag may appear dead, fail to reconnect to Find My, and become effectively useless until the battery is replaced again. That risk matters because AirTags do not recharge and do not function without a working battery. When a fresh battery is installed correctly, the AirTag should make a sound, confirming power. If it does not, the battery type, coating, brand compatibility, or orientation may be the problem. The practical fix is simple: buy a CR2032 3V lithium coin cell specifically labeled as compatible with Apple AirTag, insert it with the positive side facing up, and confirm the startup sound. Reputable uncoated or AirTag-compatible brands are generally the safest choice.

Apple's second-generation AirTag is selling at a 21% discount, marking its lowest price yet and undercutting its October Prime Day level.
The sale spotlights the updated tracker’s main upgrades over the first model: a 50% louder alarm, a new sound, and improved Bluetooth and Ultra Wideband range.
The device still relies on Bluetooth and Apple’s Find My app to locate tagged items, with Precision Finding features working best on iPhone 15 or newer.
The discount matters because Apple deals at this depth are uncommon and often short-lived, making the tracker a cheaper entry point for travel and everyday item tracking.
