Customer Ratings & Reviews

My smoke detector started chirping at me... you'd better believe I'd replace the batteries with duracell's! They have a super long life, so I know I won't have to change them again for years to come.

This was my yearly 9V battery purchase for our fire detectors. We change them out the 1st of every year with a battery check every few months. Duracell is always a dependable and affordable choice!

I always buy Duracell batteries. The 9V last a full year for the smoke detectors. The cheap batteries, you have to replace twice a year, not worth the time. Best Buy price matched, happy about that.

I always use Duracell 9V batteries in our Smoke Detectors because they last a long time. The smoke detectors are very high and don't want to use batteries which will need to be replaced frequently.

I have found that the Duracell's last longer and overall, and keep at a higher voltage longer than most other batteries offered. Many electronic companies suggest using these due to that very reason.

These batteries are a bit pricey but sometimes the extra cost is worth it. I had been using a cheaper brand in my smoke detectors but recently kept getting dead batteries and many batteries that didn't last more than a few days. I decided to give this brand a try a few weeks ago and so far they've put an end to being awakened at 3am by the sound of chirping.

Good batteries energize me. I am always happy to find long lasting, solid batteries in my portable electric devices. In my opinion, Duracell produces batteries that are among the best on the market.

What can I say...its a battery, just bought it because that's what the store had. In the past it seems like Duracell lasts longer than some other brands...guess the commercials are right

They work! What kind of review do they need? They have been around since I was a kid and work as advertised! What more needs to be said? If you need AAA or AA batteries, this won't work! LOL

The batteries have good life and the product is priced fairly.

This is for 9 volt batteries. I needed these batteries for all my smoke detectors, basement, main floor and upstairs. I know from past experience these will last for a full year.l

I chose the Duracell 9 volt batteries for a smoke alarm. The price was comparable to other name brands and I know that I am safer with a smoke alarm that has a Duracell battery.

Good price and item works great with the toy. Good brand

Duracell batteries are always my first choice. I picked these up for a remote control car that my grandson had received as a gift. We had that toy up and driving in no time.

The 4-pack of 9V Duracell batteries is perfect for my house. There is absolutely no reason to go with second best in protecting your family and your home. You know I'm right.

These batteries are great. They hold a charge for awhile and last a reasonable amount of time depending on the use. Just what I would expect from Duracell.

Not all batteries are the same. I use eminem stage in the band. Cheap batteries die fast. Can't happen at a gig. So use premium batteries. Duracells are premium. They last

I would rather pay a little bit more to have the battery last as long as possible, which means that I can wait as long as possible to face the annoying task of replacing it.

These always have a long expiration date. And of course they have a long life once you start using them - always toss a few extra in my bag when I am traveling!
