Quality batteries
on July 15, 2026
Posted by: KrisW
Great batteries for my smoke detectors and metal detectors. Very reliable and lasts a long time. A good value since they do last longer than the dollar store brands, and nobody wants to skimp on prices when it comes to safety and your smoke detectors

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.

I have always used these for all of my smoke detectors. Duracell is the one brand I trust with my families safety. They last much longer than others.

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 there is! The only one I trust for my smoke detector, the one and only! This has been my favorite brand of battery for so many years. Quality, performance, assurance, workmanship and always lasting power is what you can expect from Duracell.

The best 9V Battery
on May 22, 2026
Posted by: JustinS
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.

This is our go to battery for you on our farm. Always keep extras on hand and I love putting them in Christmas stockings as stuffers. Long lasting and dependable.
