Trusted for the important stuff
Reliable and long lasting. Truly trusted for the most important things in my homelike smoke detectors. Easy to find in stores and online. Even though off market brands are cheaper, I trust Duracell for the important stuff

Trust
The packaging of the Duracell 9-volt battery is labeled very well to let you know product. Duracella's a reliable battery and I trust it for its known current and power to trust in my smoke detectors.

I use these for all the smoke detectors in my house . They are last longer than other brands. They fit perfectly in the smoke detectors. I’ve never had any issues with them.

Long lasting
I bought these batteries for fire alarms in my house and these are amazing. Their power is amazing and they run very long time. I didn’t see any leakage or buildup around them. These are easy to dispose and easy to store.

Duracell- dependable for many uses
Definitely my go to battery brand for use in all household items that require 9v. Only battery I use for smoke detectors. Duracell 9v was luckily still good in the battery pack in my recliner when I was laying in it when the power went out for many hours . Thankfully, I was able to get out of my recliner unscathed because of the Duracell batteries in the back up-power pack of the recliner! 😊

One and done battery packs.
I’m in my last few batteries but these lasted me a good four years. We use these for certain electronics and these last really long. One machine I use them for is a electric muscle massager which uses a lot of power and it’s 60 minutes per session. One battery lasts me weeks with continuous use so that means their capacity is really high and they drain slowly. They also offer a guarantee that if you’re not satisfied with the product you can call the number in the back and I assume they’ll give you replacements. Although these packs can be expensive, it’s one of those purchases you buy one time and you’re set for years.

Been on these since the 80’s
From race car tracks teddy ruxpin to remote control cars and smoke detectors. I grew up in the 80’s where to see if these 9 volt batteries still worked you would lick them.

Great battery
One of the best and most reliable batteries out there. Not a huge need for 9V batteries much anymore but when I need one I go with Duracell every time.
