Amazon BasicsCR2032 Lithium Batteries, 4-Pack, Child-Proof Package, Non-Coated - AirTag Compatible

They're batteries. They work. But like many button cells they are coated with a bitter chemical to keep children from swallowing them. A simple solution I can appreciate. But wipe that off before putting one in an AirTag (may as well for other devices as well.) AirTags are designed to warn when batteries get low and are especially sensitive in this regard. Normally that's what I'd want given the application. So good for Apple's design team. But the coating on some batteries can be enough to prematurely trigger this warning (added resistance from the coating?) My experience with these batteries seems to follow that pattern. Two good ideas can conflict. As a prophylaxis I just rub the contact surfaces with my shirt tail before installation now.

The Amazon Basics 4-Pack CR2032 Lithium Coin Cell Batteries are a great, affordable option for powering devices like AirTags, remotes, and other small electronics. These 3-volt batteries provide a steady, long-lasting power supply and are mercury-free, which is always a bonus for those looking to make more eco-friendly choices.They last a good while, and with a 4-pack, you get plenty of backups when you need them. The batteries fit securely into my AirTags, and I've noticed that they don’t need replacing too often, making them a cost-effective solution in the long run.While these batteries are just as reliable as the big-name brands, they come at a much better price. Overall, if you need a dependable, budget-friendly battery for your gadgets, the Amazon Basics CR2032 is a solid choice.

Got these to replace the batteries in my car remote and they are super nice and great price. Easy to install and so far they are lasting. I was a little worried since i have never bougth this brand before but so far they are lasting

Don’t last very long.

These batteries are perfect for AirTags and the same size for my key fob for my car!I bought these batteries primarily for my Apple AirTags, but they’ve been just as useful for my car’s key fob. One of the best things about them is that they don’t drain from simply being left in the car! I always keep a backup battery in my glove compartment, just in case my key fob battery runs low.The last time I relied on a different name-brand battery as my backup, it was completely dead when I needed it—leaving me unable to start my car. That’s not a risk I can afford to take again. These batteries, however, have been dependable every time. They hold their charge well and work exactly as expected. They are way less expensive!The other thing that is nice is, I can be super far away from my car and this one must have more power! Because I can be further away and still lock my car when I forget! We also use an AirTag on a watch for my toddler in case he gets away from us in theme parks and stuff. So having a stronger battery is really important!

Works well and thus far have great longevity with their charge. These are a great value when compared to the name brand batteries and, of course, delivery was quick!

Nice pack of batteries for the price if you only need a few or are planning to use them for one thing. They will last forever. You just pop them right in and they do the trick on their own, easy to install, and they work well.

Exactly what we needed for the car key battery. Will purchase again. Easy to use and good price and arrives quickly.
