Duracell Coppertop 9V Alkaline Batteries 2/PK

Once I found out that the only commercial Alkaline batteries made in America were Duracell, now make it a point to use only Duracells! Less time in trans shipping stuck on a boat in the middle of the ocean roasting in a Conex for weeks on end! And by getting Duracell, that means more life for my appliances because of less abuse between the factory and my home.

I have a smoke alarm in my home and I expect the best and reliable battery so i always use Duracell 9V. It's long lasting and good thing I've only had a cooking mishap warning,

Not exciting… but absolutely essential. They last, they don't die randomly, and they show up when you need them—smoke detectors, thermometers, random things you forgot even take a 9V. You pay a little more, but you're not constantly replacing them or second guessing if it's the battery. One of those “buy it once, don't think about it again for a long time” items. Reliable, boring, perfect.

There are purchases you make… and then there are decisions that quietly secure the future of your household. This 4 Pack 9V Battery falls firmly into the latter category. When the package arrived, I’ll admit—I felt a sense of calm I hadn’t known I was missing. Four pristine, rectangular pillars of potential, sitting there like a tiny, voltage-based council of elders. I didn’t even need them immediately, but just knowing they were present? Powerful. I eventually installed one into a smoke detector that had been chirping every 47 seconds like a passive-aggressive bird with a vendetta. The moment I connected the terminals—silence. Not just the absence of sound, but a deep, meaningful quiet. The kind that makes you reflect on your life choices and maybe drink a glass of water. Performance-wise, these batteries don’t just “work.” They commit. There’s a sturdiness to them, a sense that they take their role seriously. No nonsense. No drama. Just consistent, unwavering energy delivery like a tiny, disciplined marathon runner living inside a plastic shell. And the fact that there are four? That’s not a pack—that’s a strategy. That’s foresight. That’s you, in six months, hearing a faint chirp and calmly saying, “Not today,” as you retrieve one of your remaining power bricks like a prepared adult who has their life together. Additional unexpected benefits: Made me feel wildly responsible for approximately 12 minutes Gave me a reason to open the junk drawer with purpose Briefly considered labeling things (didn’t follow through, but still) Build quality is excellent. The terminals snap with authority. The shape is iconic. Honestly, if rectangles had a hall of fame, this would be first ballot. Would I recommend this 4 pack of 9V batteries? Absolutely. Not just as a product, but as a lifestyle upgrade. Buy them before you need them. Become the person your smoke detector already believes you are.

Duracell is the only battery brand I will buy. This decision stems from decades of battery purchases. Duracell simply lasts the longest. And if it costs a little bit more than competitors, I will pay the extra for that longevity.

IT'S THAT TIME OF YEAR TO UPDATE ALL YOUR ALARMS. DURACELL IS DEPENDABLE ,EVEN IF YOU PASS THE CHANGE DUE DATE PROTECT YOUR LOVED ONES ,"A MUST" !! CHEAP DOSE NOT PROTECT LIVES .

The price was comparable to the competition. They were charged upon arrival. We will need to see how long they last. We bought them for a TENS device. So far so good. Four sessions completed and still test full of power.

The reason for the low star rating is I never received the product. I have checked with the postal carrier to see if, it was inadvertently placed in the outgoing mail slot by accident. I know Bat, the delivery driver was at my apartment building. However, after checking my email of the delivery notification. I went to check for my shipment and nothing was there. I looked all over the front area of my building with no avail. I have always had a great experience with Duracell Batteries but, I couldn't give my honest opinion if, I never got them. I might have been a victim of porch piracy. I would like a possible refund or replacement of my battery order just sent through the mail instead. Thank you for time and assistance in this matter.

Can't depend on getting your product. Walmart canceled my order. I highly doubt it was a stock issue. They said a delivery issue. I am here and no reason to not deliver.

It said 5 years guarantee but when I opened the package the battery shown 4/2029. I received on 4/4/2026. That means the battery will last only 3 years. It is cheating !!!
