Customer Ratings & Reviews

Placed in all of our homes smoke detectors. I feel confident these batteries last the full six months. Very pleased with Duracell. Always test your smoke detectors weekly! They do save lives!

Long lasting and comparable in price to competitors...

I bought these high-quality Duracell Batteries to replace the batteries in the upstairs smoke detectors. I try to remember to replace them each year and trust the replacement job to Duracell.

It was time to update the batteries in the old smoke detectors so wanted to get some that I knew would last the year. It's one of those things that its worth the additional 50 cents over generic.

I continue to be most pleased with duracell batteries

More trustworthy batteries than generic off brands

Good Item. Nice packaging. Highly recommend to buy.

There seems to be a shortage of 9-volt batteries in other stores, but Best Buy has them....and Duracells, no less! Always my go-to battery brand - they last the longest, and I'm glad Best Buy still stocks them!

I was leery of buying Duracell batteries at Best Buy, thinking they would be more expensive that a department store. I was wrong, great price. I always use Duracell for my toys and games for a long live.

I bought these for my daughters bouncer before she was born, she used it a lot because she really enjoyed being in it. She's now over a year old and the batteries are still going strong!

These type batteries are seldom used this day and age, but if they are being used, once they wear down, it is very important to replace them. Mine are used in older model smoke detectors, so the use of these batteries is very important. This brand is considered one of the best for batteries, I agree because they last a long time.

9volt batteries for her smoke detectors that is. These batteries fit right into the device and powered it up. I can now sleep peacefully knowing that my smoke detector will wake me in case of a fire.

I've had this in my remote garage pad for over a year and through a very cold Ohio winter. Shows no signs of power loss at all. Duracell has always been a solid performer for me.

Seems that 9v batteries are going to be pricey no matter what so at least these seem to last in my remotes and smoke detectors. I just change them every year. It's just easier

I've always relied on Duracell for my batteries. Their 9V batteries have a very long shelf life and work life. One of these packs covers my needs for a few years.

This 4 pack of Duracell batteries provides enough power for smoke alarms and garage remotes for years. Its always a pain swapping out these batteries so a strong power source is great!

My Duracell batteries deliver strong performance under all conditions and not just weather related. Extremely long lasting in cameras and all remote control devices.

These are strong name brand batteries that should work about as well as any others, lasting several years in my smoke / CO detectors. Unfortunately, I realized when I got home after purchasing that I still have a leftover pack of 9V batteries that I hadn't used. . . so, It'll be a while before using these.

I will always use these for my smoke detectors especially the one I need to get a ladder for. Longer lasting than any other 9volts I have used over the years.

I like to get Duracell 9 volt batteries in the value pack as they're cheaper in price than getting one at a time. These are great for smoke and carbon monoxide detectors.
