Customer Ratings & Reviews

Energizer batteries always seem to work good. We usually use this brand.

I am usually Duracell battery fan. But after I try Energizer, I see a difference between two types of the battery. It actually lasts longer than Duracell.

The batteries in my smoke detectors were chirping away, so picked these up when I got my phone. They are batteries, and they work. What more can I say?

The batteries performed exactly as I would expect a product from the Energizer Bunny to perform. They worked very well.

Can't go wrong with Energizer 9V batteries. They are all I use in my electronic devices.

and also reliable and long lasting. All smoke detectors are now set for awhile.. the low battery chirping was driving me crazy before I copped these sweet 9Vs

Excellent battery…. Last a long time. Would purchase again

This nine-volt battery appears to be working okay. It was simple, quick, and easy to install and connect. I would have preferred to purchase a single battery, but I understood only a two-pack was available.

I always bought cheap batteries but they don't last, this energizer batteries work well and last longer, worth the extra money.

Smoke detectors no longer chirping! The bargain batteries installed by the builder didn't really last, but these Energizer batteries run strong for years. Silence in the house now.

gets the job done, very reliable and you get a reputable brand

Good strong piece of tool to keep on hand or house

I used reward credit to purchase these batteries. They were one of the few items in the store that were at or below the rewards certificate value I had.

These are the best batteries. Long lasting and never any problems with them in my devices. This is the only brand I ever buy and will ever buy.

Energizer MAX 9V batteries are long lasting and exceptionally batteries.

Date showed new on the box...batteries weren't about to expire. We replace our fire alarm batteries twice a year. After batteries are taken out of alarms, we put in other toys for the kids.

Great product and cheap price. Arrives in good packaging.
