Customer Ratings & Reviews

needed batteries for smoke alarms, others did not work . These worked like a charm right away . What a difference a few volts make !

The ( copper ) top of the line of the battery universe . The standard by which all battery brands strive for . Don't settle for less !

Since my house hasn't burned down, I can say that these batteries are doing terrific job of keeping my smoke detectors in working order.

I purchased these batteries in June and they are still working. I tend to buy Duracell batteries, because they last longer than most!

this was 50% off and free shipping good buy to replace the smoke alarm battery Best Price Best Shipping = BEST BUY

I use batteries for my guitar pick-up, so I have tried various brands. These are strong and last as long as more expensive ones.

I have always had good experiences with Duracells. Usually pay a little more but am more confident I'll receive a high quality product. Dependable. I especially like the dating/expiration system to help me know I am getting a fresh battery with longest life.

I always use Duracell batteries for my smoke detectors. I need a battery I can trust and these fit the bill. Excellent power!!!

Battery was a replacement for a battery in my garage door opener that had quit operating. the new battery solved my problem.

This large pack makes it really affordable to change the batteries out every year in my 11 smoke detectors throughout my home.

Batteries are great and worked well in our alarm system notification when someone enters the store. They worked very well.

the Duracell 9 volt last longest in my pocket radio , than others are cheaper in cost

Needed some replacement 9V batteries, and job done. I've always been a fan of Duracell and wasn't disappointed with these.

Replaced batteries in the smoke detectors and they're working just fine. I expect nothing less than this from Duracell.

I use Duracell for many uses, but especially as the battery of choice for smoke detectors and other important backup items

I don’t even try other batteries anymore...Duracell are the absolute BEST battery and last the longest.

I can depend on Dura-Cell for my smoke alarms & other life critical devices (carbon monoxide + natural gas alarms).

Bought these batteries when they were on Deal of the Day. Quality product with an outstanding price.

I was driving into work today just thinking about it and it put a smile on my face... I just had to write a review!! Thank you Duracell -it is clear you put so much love into my battery!! Xoxo
