Energizer - 2032 Batteries (4 Pack), 3V Lithium Coin Batteries

Sure, they don’t get as much attention as your classic AA or AAA batteries, but the humble CR2032 has become a crucial part of our technology fabric. You’ll find the little coin cells in everything from car keyfobs to LED tea lights and torches, calculators to bike lights, and a wide range of security and wearable devices. Why? Because they’re roughly the size of a 10p piece, deliver a constant 3V output and last for ages, especially in devices that aren’t active for long periods of time. Like all good things, though, they regularly need replacing, and it makes sense to get the longest-lasting, most reliable CR2032 batteries you can find. We’ve tested a selection from all the major manufacturers, along with some smaller brands, to help you make the right choice.

There's really nothing else to say but that these batteries are just working as intended. I needed one pretty quickly due to the fob for my 2022 Nissan Sentra SV signaling a replacement. One trip to the store and a two-minute install later, my key was energized. Packing was a neat surprise, with how easy it was to remove the batteries. .The only real issue with the purchase was that it was more costly than at other retailers.

They are batteries that work and won't spontaneously combust out of the package. It fits in an air tag and replaced my watch battery so that's a win in my book.

This is a difficult product to review for the simple reason that it either works or it doesn't. Not much in between. I needed ONE battery to replace a dead CMOS battery in an antique computer that I keep running to access the truly ancient 6" and 3" "floppy" drives if you remember what those are! Plus a favorite games DUNE I and DUNE II are so old as to not function on newer systems. At any rate my machine utterly failed to boot one day and it took me forever to remember that there was a CMOS battery that I'd never replaced. UNTIL NOW. That's the good part of the review -- the not so good part is needing to buy TWO. By the time this replacement battery dies (hopefully not soon) the second will likely be lost and worthless.

Batteries worked as intended. Package was very durable. I previously purchased the same batteries years ago, so the battery life is long I used this product for a car key remote and fog machine remote.
