Customer Ratings & Reviews

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

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!

These things last forever. I use it for the smoke alarm and I change them once a year. They still have life in them but just to play it safe I always change them once a year. It's always best to do that because if you wait for the device to beep maybe you say I'll do it tomorrow or you procrastinate with other excuses. I like to do it the way I've been doing it.

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

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

Since I haven't had the need to use these batteries yet, I'm hoping that they're as good as the ones that I've bought in the past. One of the Eveready batteries that I bought from Best Buy in the past had a dent in it, but the Burbank store wasn't able to give me any kind of store credit since the time had run out on my receipt. I don't think that any one uses all the batteries that they buy as soon as they get them home.

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

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

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!

Good batteries to have on hand for garage and smoke alarms

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

Quality batteries that last a long time and are affordable.

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

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 Price for replacement batteries for smoke detectors in the house. Always need to keep some on hand for those midnight wakeup beeps!

Energizer MAX 9V Batteries (2 Pack) 9 Volt Alkaline Batteries. Energizers max are great for my uses.

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.

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 use these for my smoke detectors, and they work well. I replace them once a year rather they need them or not.

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)
