Customer Ratings & Reviews

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.

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.

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.

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.

Battery works great for me but cost too much for little thing

I like the price and how it's always guaranteed to be legitimate at Best Buy.

Battery is working good I pretty much like these brands. I always go to Best Buy every year for my batteries.

Excellent batteries they last a long time and are very reliable

The battery works well. I had to replace my fob battery and this was the specific size. Energizer does use a blue dye with these batteries. When moisture is detected the blue dye is present on the surface. It’s a countermeasure against children swallowing these batteries. Just know if you get blue dye on your hands from one it will wash off and is food safe.

How to write a 50 character review on batteries? They power my keys with incredible power! They fit in the temperature sensor that allow me to control my home thermals with precision power! It’s Energizer right, I mean I could just keep going, and going, and going, and going…

The Energizer 2032 3-volt battery battery 2-pack offer a wide diversity of usage. I recently used it in my Bose Wave Radio remote control and my Universal Garage Door remote control electronic devices. Both the radio and garage door now function as wonderfully as the first day I used them. I am so pleased that I went out bought another Energizer 2032 2-pack to have on hand for potential emergency situations for my other electronic devices.

Arrived on time. I always like to keep extras on hand to ensure my car's key fob will work properly.

The best batteries in the world by energizer, recommended

Needed these batteries for a few of my Angel ornaments that happen to light up and change colors.

I used these batteries for my key fob! It did its job.

These batteries always work well in my key fob and always last long. I would not use any other brand other than this one. Fully recommend

Great value of the product and customer service from Best Buy.
