Duracell CR2032 lithium batteries are a dependable choice for devices that need consistent, long-lasting power, and this 8-count pack is especially practical if you use multiple small electronics. They’ve been solid performers across everything I’ve used them in, including AirTags and key fobs. Performance has been excellent. Once installed, these batteries just work and keep working. Devices stay powered reliably without sudden drops or early failures, which is important for things like AirTags where you don’t want to constantly check battery status. They provide stable output and hold their charge well over time. Compatibility is exactly as advertised. They fit properly in AirTags, car key fobs, remotes, and other devices that require CR2032 cells. There are no fitment issues, and the batteries make good contact right away without needing adjustment or reseating. The child safety features are a thoughtful addition. The bitter coating helps discourage accidental swallowing, which is especially important in homes with kids. It’s a small detail, but it adds peace of mind without affecting performance or installation. Shelf life is another strong point. These batteries store well and don’t lose charge sitting in a drawer, so buying an 8-pack makes sense. You can keep spares on hand and know they’ll be ready when you need them. Packaging is secure and clearly labeled, though opening it does take a bit of effort, which is common with battery packaging. Once opened, the batteries are easy to store and organize. Overall, these Duracell CR2032 batteries deliver exactly what you expect: long life, reliable performance, and broad compatibility. If you’re powering AirTags or other small electronics and want a trusted battery that won’t let you down, this is an easy five-star choice.

Lots of generic versions of this battery are being sold everyday right here at Amazon. Granted, some generic versions are better than others yet none of them compare to the quality and durability of buying a national brand like Duracell. Here's proof. Buy an inexpensive battery tester and prove it to yourself. I put a generic battery in one of my car key fobs and put a Duracell battery in the exact same duplicate key fob and tested them daily side by side for 90 days. (SEE PIC) The end results were that after the initial 90 days when I tested both batteries afterwards only the Duracell battery tested as equally powerful as the day it was originally installed. The generic battery was more than 50% drained of its power and the key fob was failing to operate at a distance from the car. Periodically on my car dash it would also read "low battery" when I started my car. Proving that when it comes to value for the money in the long run, the longer lasting Duracell battery is worth it's weight in gold. However, for those of you more interested in learning information about the shelf life, its stamped expiration date from my most recent Amazon purchase here is Jan 2034. (SEE PIC) That's of course when storing the batteries under the most opportune conditions which for me isn't always possible. None the less, factoring in the shelf life of the batteries and their overall longer battery life while in use compared to most generic brands, they're a great value if not the better bargain actually for the price. The only way to test batteries accurately is to duplicate the functionality when in use and the key fob test I conducted accomplished just that. The only downside to the purchase here is that it's not so easy to just jump in carefree and open the initial packaging to get to the purchased batteries. However, carefully cutting along the designated lines on the back of the package to access each battery storage compartment successfully solves that problem in a jiff. (SEE PIC) I've bought generic batteries in the past and they were so carelessly stored not at room temperature by the manufacturer that some of the batteries themselves actually stuck permanently to the packaging totally destroying their practical use. That's not a problem here with these properly stored Duracell batteries. I can assure you that. The bottom line is simple. Go right ahead and make the actual purchase. You can't go wrong. Why buy cheaper inferior made batteries that fail prematurely. Leaving you when opening your car door on one snowy or rainy day very soon literally left standing out in the cold.

I’ve been using the Duracell 2032 batteries for several months now, and they never disappoint. These batteries last a long time and work perfectly with my Apple AirTag, car key fob, and other small electronics. I appreciate the child safety packaging, which gives me peace of mind at home. The batteries are genuine Duracell quality—no leaks or performance issues so far. If you need dependable CR2032 batteries that keep your gadgets powered up, this 8-pack is a great value. Highly recommended!

I bought these to replace the dead batteries in my airtags. They work insanely well and last a very long time

So, I originally bought the Amazon version of these batteries and was so disappointed. They did not last at all. I put these replacements in my little tea light candles and oh my, what a difference! Brighter right away! And they should last a lot longer than the others.

Duracell is a good, reliable battery - and the things you put “coin” batteries in depend on that. AirTags, car fobs, etc aren’t places to save a dime on a battery. Contrary to some reviews, these batteries DO work fine with Apple AirTags, even without going through gyrations of cleaning the bitter, child-deterring coating off. I suppose if the battery contacts in your AirTag are getting weak, you may have a problem, but I had no issues. If you’re intent upon cleaning the coating off. A paper towel slightly dampened with plain old water should do the trick. No need for a stronger solvent. Battery life is excellent with devices in good working order and clean contacts. This 8-pack is an excellent bargain when compared to single and 2-packs. I suppose the “bitter” coating is a nice plus if you’re worried kids may swallow them. I’d give this product 5 stars except for one reason: without a scissors - or risking injury with a knife - it’s about impossible to get the battery out of the package! I like to keep a spare or two for my AirTags when I travel, but with TSA rules these days, I can’t bring along anything sharp to open them! By all means - let’s keep kids from swallowing batteries - but please - DO make it possible for adults to open the package!!! Duracell should offer these batteries in a package for households without children. It would save the rest of us the trouble!

We have multi air tags and all the batteries have lost their power. We replaced at least 8 batteries

These Duracell 2032 batteries work perfectly and last a long time, but the packaging definitely prioritizes safety—which is both good and frustrating. The child-resistant pack gives real peace of mind, but as an adult, it took some effort to get a battery out. Once opened, though, the batteries perform exactly as expected. Excellent quality and a smart design for households with kids.
