Customer Ratings & Reviews

Bought this 4 pack of 9v batteries for my beeping smoke detectors and they've all worked fine. No issues at all.

I purchased the Duracell - 9V Alkaline Batteries (4-Pack) - Black for my smoke alarms and wanted reliable batteries.

Always a good value for batteries. The batteries seem to last longer than other brands and we a loyal to this brand.

Used for CO2 detector and smoke detector. I changed them after 6 months of use. Had no issues with them whatsoever.

I bought these 9 Volt Batteries for replacement in my smoke detectors. I also saw Energizer and Rayovac. These Duracels (made in USA) and the Engerizers (assembled in USA) both had the same expiration date and we're both completed in the USA. The Rayovacs were made in China. I've had good luck with both Duracel and a Energizer, but I like the fact it seems like the Duracel was mainly manufactured in the USA, versus assembled in the USA, and made overseas.

They work just fine. I put them in my tool and it worked. Ok they are batteries. Nothing special but they worked

these are good batteries at a great price can't find these at other dept. stores at this price

Certainly this is not a bad thing to be said about these batteries. It is an excellent company

Great batteries. Long lasting. I never thought i would need theses batteries but i am glad i purchase this brand

In my experience, batteries are batteries, this was on sale, and I have not been disappointed

Best duty, does last longer than others. Don't worry about saving a couple dollars, performance is performance.

My smoke alarm needed a new battery, so I bought these batteries and they work great and last a long tim.e

My smoke detector batteries were running low & these were good inexpensive durable batteries

Awesome batteries that will come in handy! I am stocking up to use during hurricane season.

Duracell has always been an excellent brand of battery and these were the right choice for my smoke detectors.

I use these every year to replace batteries in my smoke detectors. They hold up well, and the price is right.

I needed 8 volt batteries for our smoke alarms and I always go with Duracell. They really are long lasting.

Great batteries. Tried off brand and they did not last long. These are quality batteries.

I have tried both Duracell and energizer batteries and by far Duracell always outlast the competitors

They are batteries. You put them in things and they give those things power. They are pretty sweet. :-)
