Customer Ratings & Reviews

I needed batteries to put in my fire alarm, and these were the ones I chose. I always trust Duracell because they are very reliable. You don't want to mess with your safety.

that hasn't already been said. I use these in my smoke alarms. I cannot remember the last time I had to change them. This is a first in YEARS. Take that Energizer Bunny!

These batteries hold their charge before use for years and once they're being used, they just last! Not much else to say; they're batteries and they work!

Very good batteries. They seem to last for a long time. It's always good to have some spares in hand as you don't know when your alarm will start beeping...

my remote car was not working, put new batteries and now it does, what an easy fix and glad i got Duracell they seem to work when the old batteries did not.

Battery is great and all but I wish Duracell sold 9V batteries in single packs.

Needed batteries for the smoke detector. Cheap alkaline batteries run out too quick. May need to upgrade to Nest.

cheap because they are running out of expiration but still good

I've purchased this brand in the past to put in my smoke dectectors. They have lasted a long time, so I don't have to replace the batteries very often.

Wow. So much wow. These have got to be the voltest 9V batteries I've ever purchased. Very satisfied with the full amount of the nine volts. Great purchase.

Need a batteries for fire alarm. This ones are great and last. So no waking up at 2 am because the fire alarm is going off because of a low battery

As weird as it sounds 9v battery are getting harder to find in a good brand, and Best Buy always seems to have then when target and Walmart didnt

Needed a few 9volts for things around the house including smoke dectors. I switch them out every and they always have a good charge left on them

I needed a 9 volt battery for a stud finder I had just purchased. Easily found it in best buy, bought it and it works just the way it's supposed to.

was looking for 4 9V batteries at a good price to replace dead batteries in my smoke detector. So far no issues and everything is working great.

Duracell are the best they last a long time. I like the freshness dating imprinted on the battery so I can always use the oldest ones first

You can always count on Duracell Batteries to give you the strength and long life you need for anything that takes batteries.Very dependable!

These batteries were great. I plugged them in, flipped the switch, any my gizmos worked. I would recommend them. Yours will probably work like batteries too.

Not sure how to differentiate the review of batteries. The Duracell are a reliable brand so I try to purchase them when I need batteries.

What can you say? It stopped the annoying beeping coming from the smoke detector. It is a Duracell, so you know it will do its job all year.
