Amazon Basics CR2032 Lithium Batteries, 4-Pack, Child-Proof Package, Non-Coated - AirTag Compatible

I bought these to replace the batteries in multiple AirTags that had run low. The 10-pack was a bargain compared to the grocery store prices, and they are super easy to replace. They fit exactly like the original batteries, appear to last just as long, and weigh the same as the originals. To replace the battery in an AirTag, all you need to do is press down slightly on the silver disc side of the AirTag and twist counterclockwise. Then drop the new battery in, giving it a slight twist to lock it back in place. Don't force it; it takes minimal effort.

Excellent batteries for the price, works just as expected. Perfect fit for my 2011 Camry keyfob. Battery life is great. Highly recommend!

Great long lasting battery four pack. Just the right size and works perfectly. Good value.

Just what I needed for my pc motherboard and my helmet led light. Reasonable price too.

I'm always happy with the price and life span of Amazon Basics batteries.

I purchased these CR2032 batteries to replace the aging/burnt out batteries in several Philips Hue Dimmer Switches throughout my household. I also recently purchased an AirTag and wanted to have a backup on hand for that device. The batteries are well-packaged and they were plenty “fresh” with an expiry date several years out. I used essentially the entire package replacing old batteries, so I only have one left in the package. Packaging is easy to open. You’ll need scissors. You make a cut across each battery section you need/want to use. The rest stay vacuum sealed for freshness and safety. Be aware these do lack a bitter agent like the name brand, so AS ALWAYS keep away from pets and children. Batteries cause internal injuries if ingested. As far as longevity goes, time will tell for a lack of a better term. Given my switches aren’t typically a high drain device, I’m hoping to get solid life out of the batteries without premature need for replacement or possible leakage, as mentioned by others. For the time being, I’m giving five stars for the amount of batteries for the money. Additionally, you usually cannot go wrong with AmazonBasic products. It was also great being able to order these for free overnight delivery vs being ripped off at the pharmacy for these batteries. If these continue to live up to the quality I expect, I plan to purchase more down the road as needed!

They fit, work well and are fairly inexpensive. I have them in all my antique cars. Appears to last 9-12 months

I only needed one battery but it's cheaper than buying one. Great for my tile connected to my key chain. Synced with my app. Now my wife can track me. (maybe it's not a good good thing)
