DURACELL2032 Lithium Battery, 9 Count (Pack of 1), Child Safety Features, Compatible with Key Fob, Tea Light Candles and Other Devices, CR2032 Battery

First - replace your airtag batteries - its super easy and convenient!These are great for airtags, kitchen thermometers, some remote light switches. These last *much* longer than the no name dollar store ones that barely lasted 2 months in an airtag. This pack is way more affordable than buying one or two in a store.As extra peace of mind, these do have the bitter coating on them to prevent kids from eating them. Look online, there are some real horror stories. I don't mind. You can wash it off with alochol if you think its a problem.

These batteries are MUCH better than the "knock off" brands that I've previously purchased here on Amazon. Call it "buyer's remose" for not having purchased a brand of batteries with a reputation of being good, reliable batteries.We are using these batteries in our dogs' airtags. The knock-off brand that I previously used kept telling me within days of installing it, that the battery was low. The expiration date was even several years in the future but in that case, it didn't matter - they were junk.I wish I had stuck to a name-brand battery. THey say hindsight is 20/20. It's a lesson learned for me! We are now much happier with these batteries.PROS: Quality, Duracell brand, long-lasting batteriesCONS: None noted at the time of this writing

I've tried a bunch of different brands of these button cell batteries and so far, these are the most reliable. While I use them in quite a few devices, I never have gotten to the 10 year lifespan of the packaging (as I use them up before that!).They don't leak and I can always depend on them when I pull them out of the package for use. I'm willing to pay a little more for this name brand.

Good batteries. They live forever in the AirTags I keep on my keys and my animals air tags.

Always good batteries. I use them in my Airtags that a put on my dog collars. I purchased some cheaper ones in the past, and they never lasted long.

Batteries are good, but I'm deducting a star for the absolutely worst packaging I've ever seen – it's impossible to open it without scissors, but even with scissors the plastic is so close to the battery that you can't cut it without damaging the battery. I have no idea what the creator of this packaging was thinking, but I hope they change it.

Great value for money

good for my guitar tuner
