While Duracell has always been a more expensive battery brand than most, it's also usually the best battery brand. In my experience, Duracell not only provides a powerful battery, but a long-lasting one. What I really like about these 9v2 batteries is their guarantee of lasting 5 years. I've used other, cheaper brands' batteries for my smoke detectors and have ended up having the detectors chirping with a dying battery after a couple years at most. I hate the chirp, and I hate changing the battery just as much. In the longterm, Duracell 9v2 batteries will not only save my peace, but also my money. If they do what they claim, they're definitely worth the price. Would get again.

Don't you hate the chirp, chirp, chirp of a dead battery in your smoke detector, especially at night when you are trying to sleep? You plan to purchase new batteries the next day but forget. Irritating chirp continues while you weigh whether to just remove the annoyance. A better option, in my opinion, is to keep a few spare ones in a handy spot, one that won't be forgotten when you need them. With Duracell Coppertop quality you can feel confident that they will perform right out of the box, unlike the cheaper brands. That's why Duracell is my first choice when buying batteries.

Our family needed 9v volt batteries to replace in our smoke detectors. We went with the Duracell brand because it's an American brand that was been around for years. We have been purchasing Duracell because they last forever! Cheaper store brand batteries and other brands simply don't last as long as Duracell. We also appreciate the 5 year guarantee on the packaging. Gives us peace of mind that any extra batteries in the package will last for years to come and won't be "duds" when you need a replacement. We only buy Duracell in our family and recommend you do too the copper topper that's built to last! Our home and family are now safe with Duracells batteries in our smoke detectors.

Duracell has once again proven themselves to me. I've been buying budget batteries for a long time as they are quite pricey and batteries are not always the first source of power anymore. However, like a blessing from above, I was able to get these as Hurricane Ian continues to inch its way closer to my home. And I've already tried them out in my lanterns and pumps, and they definitely crank the machines stronger and brighter than the other batteries I was using. These are 100% my top pick for emergency batteries in the future.

The first impression I got from this product was the "easy open" tab how easy it was to open it and very fast, Branding: Good old Coppertop - love it. And, considering that the previous batteries were Energizer, the distinctive branding helped me keep the new batteries and old batteries separate as I addressed my light mirror. Really forward thinking on Duracell's part, super job. Ease of use: Wow, really impressive. They slipped right into each mirror like they were made for it. Super job. Performance: The light mirror is no longer glitching, so I really feel like the batteries are doing their job.

It's expensive for two 9v that don't go to everyday items. I use two of them to power my cats auto feeder, so the idea of guaranteed 5 years that's on the package seems to only to ridicule the customer. There's no way I am gonna keep my eye on it for five years. The batteries work they seem to be very durable and give good power. They are reliable for the purpose of use but the price is overbearing. I see that it is worth for they do last quite a good time. Overall I am satisfied with the product and will continue to use of it considering the power and durability it provides.

If you have ever needed batteries for any devices in your house, then the name Duracell is sure to ring a bell, and not just because you need batteries, but also because Duracell has long held a spot for making some of the longest lasting batteries on the planet. These 9V batteries are no different, they work great and always last a very long time. Currently, my little girl is using one in a talking doll she has. It should last her awhile as the last one in it lasted a good year, so it keeps her happy and that's what matters. When it comes to batteries of any type, I've always been happy with Duracell and will continue to use them whenever necessary. The reliability and how long they last is truly hard to beat. If you want the best of the best, get Duracell.

I purchased the 2-pack Duracell 9V batteries for my smoke alarm. It's been "chirping" which is a clear indicator that a new battery is needed. I have arthritis in my hands and the packaging was easy to open. No messy pieces of paper to throw away, as I only needed one of the 2 batteries. The other battery is still snug, inside the package. I can easily store this small package in my cabinet until needed. Duracell is my Go To battery of choice.

I don't get it. How does one company constantly provide a perfect product without any defects? Duracell has never let me down. The batteries are always packaged perfectly and the batteries inside are never damaged or old looking. I can store these for a couple of years at least and still break them out and have no issues with their life span. I don't have too much need for 9V batteries, but we do have one radio for emergencies that has always run on them and always have us days of use before dying. I am sure these will be the same thing. The radio works just like new with this battery in it and turning it on. 100% A+ batteries

The batteries were received in perfect condition. Needed some new ones for a smoke detector and it worked as soon as I connected the new battery. The last Duracell battery in there lasted some years at least and I will assume this will do the same. I have no worries when using these batteries for something so important. I do wish that the perforated part on the back to open the package was actually two of them so I could easily pull one battery out after tearing it open instead of having to rip more of the packaging to get to one battery. It would just make it more simple. However, this is my go to brand and will buy again either way.
