Replacement for Apple AirTag Battery, Perfectly Fits AirTag, No Bitter Coating, OEM CR2032 3V Batteries (Pack of 4)
Quick take
This 4-pack of CR2032 3V batteries is made to match AirTag’s fit and contact area, with an emphasis on avoiding “bitter coating” that can interfere with connectivity. It is a good choice if you want spares ready and a DIY swap process, but it will only work for devices that take CR2032 and where you can open the AirTag to replace the cell.
Pros and cons
Pros
- Designed as an AirTag-specific CR2032 replacement (3V lithium, CR2032 format).
- No bitter coating, intended to help prevent connectivity issues at the contacts.
- Includes four batteries, handy for keeping spares.
- Step-by-step installation video is included.
Cons
- Airtag cover shell is not included, so you need the existing shell on hand.
- CR2032 is required, so it is not a universal battery for other trackers.
- Buyer-review comments about “battery life” are limited, so long-term endurance is hard to confirm.
What buyers think
Buyer-review evidence is limited in detail, but the feedback that is available points to consistent, practical use: most comments describe the batteries as working as expected in AirTag devices, with easy installation and “works well” outcomes. Some reviewers briefly mention device behavior after installation, but there is not enough repeated, specific battery-life reporting to draw a reliable pattern about how long these particular cells last versus other CR2032 options. Overall, the review themes lean positive on compatibility and day-to-day functionality.
What you get and what matters for AirTag replacements
AirTag battery swaps are simple when the replacement cell matches the device contacts and physical fit. This pack is built around that idea, using CR2032 3V lithium cells in a pack of four. The manufacturer messaging focuses on two practical concerns that tend to show up with non-matching third-party cells: fit and contact behavior.
Fit and contact behavior
The key differentiator here is the “no bitter coating” approach. Bitter coating is sometimes used on coin-cell batteries to discourage swallowing, but for certain battery-contact designs it can cause contact issues. The product is positioned to avoid that problem, aiming for stable connectivity after replacement.
DIY convenience
Replacing an AirTag battery is easiest when you know the steps. This pack includes an installation video intended to guide the process. You will still need to handle your own AirTag opening and replacement using your device’s parts, since the cover shell is not included.
Pros and cons for real-world buyer fit
Who this is best for
- You own one or more AirTags and want a multi-pack so you do not have to hunt for batteries later.
- You are specifically concerned about third-party coin-cell replacements causing connectivity hiccups, and you want an option that addresses bitter-coating interference.
- You want an AirTag-form-factor CR2032 replacement and value instructions that make the swap quicker.
Who should skip it
- You need batteries for a device that does not use CR2032.
- You prefer a pack that includes replacement shells or additional AirTag parts. This one only covers the batteries.
- You require strong, repeated evidence of long battery life performance. The available feedback is not detailed enough to confidently compare longevity across brands.
Is it worth it?
If your main goal is a CR2032 replacement that is meant to fit an AirTag and reduce the chance of contact-related connectivity problems, this pack is a sensible, practical buy. The included video and multi-pack format make it especially convenient for households with multiple trackers. The main limitation to keep in mind is that it does not include an AirTag cover shell, and the available review evidence is not deep enough to strongly validate long-term battery-life differences.
FAQ
Does this battery pack work for Apple AirTag?
It is intended as a replacement battery set for AirTag devices that use CR2032 3V coin cells.
Is the AirTag cover shell included?
No. The pack includes the batteries only, not the AirTag cover shell.
What does “no bitter coating” mean for AirTag performance?
It refers to avoiding a bitter coating on the coin cells that can interfere with the battery contacts in some devices, which may lead to connectivity problems. The goal is more reliable contact after replacement.
Is an installation guide included?
Yes. A step-by-step installation video is included (via a link associated with the packaging).
How long do these batteries last?
Review detail about longevity is limited, so it is best to view battery life as variable by usage and your specific AirTag activity rather than something guaranteed by the listing.
How many batteries are included?
This is a pack of four CR2032 batteries (3V).
