Customer Ratings & Reviews

Always a good buy for batteries. I use these for my guitar and get about a year out of them.

Good quality and the price is very resonable. I recoomend instead of the orher high price batteries.

Excellent. We use these in our smoke detectors every year so we always have a supply on hand.

I bought Duracell as I used it with my smoke and carbon monoxide detectors. Saftey is paramount and I knew it will last the 6 months and then some.

Wonderful batteries at a good price. I really like the Energizer brand for dependability.

Great 10 volt battery! I use these all the time for smoke alarm. They last a good long time.

Good batteries for everyday use Would recommend if need good battery

Good ones but too expensive. After buying them compared prices from other stores and were way expensive.

Good stuff that works well. Energized and ready quick

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!

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)

Very effective for my two fire alarms! they are working fantastic.

WE needed these batteries for our smoke detector and they worked great.

It's a bit odd to write a review for batteries, but why not. Mostly needed for smoke detectors.

The energizer batteries are the only batteries I use they seem to last longer.

Good batteries for the price point! Lasts a long time!

Battery last pretty long. Energizer never disappoint.

Dependable and trustworthy. Good brand and does not leak.

I needed this for an old handheld Sanyo radio. Works great and lasts long.

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.
