Customer Ratings & Reviews

What can I say? These batteries worked fine. I used them in a remote control for a ceiling fan.

Perfect for my beeping smoke alarm. Haven't replaced it in over a year since.

Don't really know how to give a rating on a battery but it seems to work

Good value for a package of standard batteries. They last as long as any other name brand

Works well even in cold weather. Better pick for the price.

Battery works well. It last longer than the dollar store brands.

The perfect price for a long lasting battery. I need it for my smoke detector and It lasts a long time.

I bought this battery without reading reviews, which is normally a huge risk. But this time it paid off. My smoke detector worked instantly when I plugged the wired connector into the battery. “Ta daaaa!” I sang out loud as the beautifully engineered(these Energizer engineers must be geniuses to have designed such a small powerhouse!) and delightfully crafted circular prongs met the contact points on my smoke alarm, sending a burst of clean power to my starving smoke alarm. I felt a sense of calm and assurance that I hadn’t felt in a long time after installing this little wonder. No worries, Energizer was here! Who can put a price on piece of mind? I thoroughly recommend this little 9v wonder!

I can get batteries anywhere but I choose Best Buy as they are my go to for almost all my needs...I can count on the quality and don't have to worry!

We are going to use these for our smoke alarms. I would hope that they last a long time as Energizer usually does. Thank you!

I love Energizer, they are definitely my preferred brand when it comes to reliable batteries. I use these 9Vs in my external audio microphone and they work wonderful and give the mic a super long battery life.

Great purchase will buy again in the future when I need more.

They work perfectly in our smoke detectors. These batteries are always available at the front of the store.

I love Duracell Batteries. They always last for a very long time. I know these batteries have the power to run most everything I put them in. I use them in my metal detector and they last a long time.

I have been using this battery my kid's car. It has good power. It's long lasting battery. Definitely Energizer is my go to brand for all kinds of batteries.

We use these in our acoustic guitars and this brand lasts a long time and is good quality. You can trust it.

Quality batteries that last a long time and are affordable.

Good batteries at a good price. They last a long time and keep their strength.

Best Buy has great prices on all their batteries. Would highly recommend shopping there.

Have been purchasing Energizer batteries for years due to their shelf life and durability. I will continue purchasing any Energizer batteries not only the 9 volt batteries because they have worked very well on items that have been purchased that require batteries. (tv remotes)
