These last the longest out of any battery that I’ve tried on my car key fobs. Love the quality love how compatible they are. They are super light. And they last forever 10 out of 10.

Last a long time!
We love Energizer for their longevity and durability. We replaced our smoke alarm batteries which provided a perfect fit. They work well and function as promised. We change them and keep a backup when we dispose and throw them out.

I tried these in my smoke detector and so far so good! It was easy to install, size is to be expected, easy packaging, and output seems to be good. No complaints here!

Great battery brand
The Energizer 2450 Lithium Coin Battery is very specific to the device that it can be used in. I know that the Energizer brand is top notch so I am not worries about it's performance and I know it was going to work exceptionally well. The price for the batteries are in the normal range. It doesn't take up a lot of space and hope to use it soon. I do recommend this brand to the fullest.

Great Batteries
These CR2450 lithium batteries worked perfectly in my digital food scale and powered it up immediately. I also really appreciate the packaging and how hard it was to open. While it took a little extra effort to open them, having young children in the home it gave me peace of mind to keep them in the battery drawer. So far I am very happy with the product snd will purchase again when my food scale or another item that takes these batteries goes out.

Def use again
The size is small and super light. I use it for my Chevy key fob which will last anywhere from 2-5 years depending on the usage. And it's super small so storage isn't an issue.

Very easy to use, I use no other brand! The last batteries I used died faster than these. I notice I dont have to change them out frequently than usual
