[This review was collected as part of a promotion.] the price seems expensive for a two pack, packaging looks cheap, but as long as they batteries work, which they do. I need them for my CO2 alarm, so can't say how long it'll last until it starts beeping. I trust that it'll last, but with the guarantee of 5 years of storage, wish I could see when it was manufactured. I couldn't find it on that packaging.

[This review was collected as part of a promotion.] I have never had a problem with any Duracell battery and the 9 volt will not disappoint. I usually put them in my smoke detectors and they last for a long time.

[This review was collected as part of a promotion.] We use 9V batteries in our smoke alarms throughout our home, and recently the one in my daughter's room started chirping indicating it needed to be replaced. I trust my new Duracell battery to work for such an important device in my home. We've always tried to use the name brands when it comes to things that are more important and I think our smoke alarms are at the top of the list.

[This review was collected as part of a promotion.] The Duracell batteries are powerful long lasting. The batteries last for a long time for all of my smoke detectors around the house. I definitely recommend these batteries for long lasting.

[This review was collected as part of a promotion.] I like the batteries because they last longer than the generic brand. The name has become a household name.

[This review was collected as part of a promotion.] What can I say they are batteries they performed as expected. They are a little pricey for only two. The price is expected as they are namebrand batteries.

[This review was collected as part of a promotion.] These batteries are great and are long lasting they couldn't have come at a better time. They're perfect for my smoke alarm in my house since it's other batteries had died.
