It was great value for what you get from the batteries. It is easy to open and store them when you don’t need to use them. It worked great as advertised.

Great Battery for Kids’ Toys!
We use Duracell 9v batteries in our son’s toys always. Especially this grave digger monster truck RC car. He’s constantly forgetting to turn the monster truck off after he is done using it and Duracell 9v seems to last forever!! This makes the quality of these batteries a 10/10 for our house!

The best 9V Battery
There are few things as annoying as your smoke detector chirping in the middle of the night. The last time it happened to me I didn't have a replacement 9V battery and had to deal with the chirp all night. Now I make sure to always have a couple extra Duracell 9V batteries in my junk drawer, just in case. Duracell is my brand of choice. They're long lasting, reliable, and have a long shelf life. They aren't the only good battery brand, but they are the best in my experience.

Duracell- dependable for many uses
Definitely my go to battery brand for use in all household items that require 9v. Only battery I use for smoke detectors. Duracell 9v was luckily still good in the battery pack in my recliner when I was laying in it when the power went out for many hours . Thankfully, I was able to get out of my recliner unscathed because of the Duracell batteries in the back up-power pack of the recliner! 😊
