Amazon Basics 4-Pack CR2032 Lithium Coin Cell Battery, Compatible with AirTag, 3 Volt, Long Lasting Power, Mercury-Free

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 as described. VFor a reminder searched the Brave app for directions how to remove the AirTag battery. Size works. Ease of use: Push lid with battery installed toward the back, and twist. Battery charge beeped when the new battery and reversing the process. Installed in less than a minute including emoting from wrapper.Glad only four included. Good value for the money. Only need one at a time. These should last a couple of years before their expiration.

I needed these for my car alarm. Even though they are an Amazon brand and not Duracell or Energizer, for the price they would really well and they last a long time. They work just as good as the high end brands & you get 4 in a pack which is not bad at all. They last a long time, I’d say they are just as good as any battery that costs more & they weren’t difficult to use. Definitely buy these, I guarantee they are just as good!

Functional, affordable, and are the right size for an exact fit/replacement. However they do not seem to last as long as the OEM ones from PetSafe. Given the reduced cost in comparison though it is still cheaper and well worth the money for the multi-pack as we have four dogs that use wireless fence collars at home.

This was so easy to install - only took a minute! It came 84% charged and is nearly up to 100% already. tested it without the AC plug and it works fine. GREAT value for the money.
