[This review was collected as part of a promotion.] The 9v Duracell battery are brand you can trust, and reliable and dependable. I've used Duracell batteries for many years and this is a brand last for long time. Most people use the 9v for their smoke detector . And they work great.

[This review was collected as part of a promotion.] I used these to replace the batteries in my smoke detectors and it worked like a charm! Really easy to install and hook up. Now I can be confident that my smoke detector will work for years to come.

[This review was collected as part of a promotion.] I like the Duracell brand because of its reputation for quality products. I use these 9V batteries in my smoke alarm and from my notes, they lasted at least a couple years on a normal case basis. I cannot attest for this specific battery's longevity but I'm hoping it's a while. I think the package's statement of "guaranteed 5 years" may be a bit misleading since in small font below that it is followed by "in storage". So I'm thinking that means it is just storing life and when the battery is not in use.

[This review was collected as part of a promotion.] These are the best batteries for our smoke detectors. They last a very, very long time, and we don't have to worry about waking up in the middle of the night to that annoying chirping noise!
