I use these in my smoke detectors and they work great. They last a long time and they are always a reliable choice. I definitely recommend these for anyone needing batteries.

Last a long time. Love when they come out with them around Christmas Or make it Christmas gift. The packs are divided into the right pairs for the item needed.

These batteries are excellent

These batteries are excellent; ever since we moved into our current home (two years ago), we replaced the batteries in all our smoke detectors, and they have been working without any problems. They are neither too big nor too small - they are an intermediate size. And they are very easy to install.

Energizer batteries are a total lifesaver! 😅 I love how long they last, because my kid's toys never stop 🤯. From the remote control car to the talking, singing robot, everything works flawlessly with Energizer.
The best part is I can trust they won't die on me at the worst moment, like when we're in the middle of a family adventure 🏕️. The durability is impressive, and that gives me peace of mind.
If you're looking for reliable batteries for your little one's toys, Energizer is the way to go. Highly recommend! 👍

I needed one for my network cable tester, and nary a store in this hillbilly town was likely to have it. Great to see it online at least. Lasts about two years for MY purposes.
