This brand is my go to when I need 9 volt batteries. I use them exclusively in my smoke detectors. These batteries have a long shelf life and last over 6 months at a time in the detectors.

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 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...

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...

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.
