Customer Ratings & Reviews

Energizer batteries are among the highest quality. I bought them at Best Buy because, using the rewards points I had earned, the price-quality ratio was unbeatable compared to any other store.

Great 9V for smoke detector or garage door opener that last a long time.

This little pink bunny is a work horse and I love these batteries. When you compare the cost of these named to no named it's a no brainer. I must say though that Duracell is a real close 2nd!!!

I was so glad to find this two package of Energizer 9V2 batteries at Best Buy. I needed them to use at my home. I have used Energizer batteries in the past and have been very pleased.

I ordered Batteries on line. The process was quite easy. I actually had them delivered to my home and wanted to see how that process was well. They were supposed to be here on a certain day and they were not. It ended up being like maybe four days when it was actually delivered!! I actually ordered something now, but I’m picking it up in the store!

The Energizer batteries are good and durable. They last longer than many others I’ve tried and always deliver consistent performance

Got these on sale as a total member and you can’t beat it. Thanks Best Buy! Now I can change all of my smoke detector batteries during the day instead of finding “the one” at 2:00 am.

Fits where a 9V battery should, snaps onto the terminal snaps perfectly. Provides power as it should and Energizer has proven to have a long shelf life.

We've all seen the bunny commercials, touting Energizer's longest lasting batteries. Hyperbole aside, they are some of the best batteries on the market for life span. You do pay a bit more than other brands (except the "Copper Tops") but you get more time without having to change them out. The downside is that you can purchase nearly twice the Rayovac or Amazon brand batteries for the same price.

Batteries are as long lasting as any others IU have used

For the price compared to Duracell, it is a good battery. Although, between using Duracell and Energizer over the time I have been buying batteries, Duracell has a longer life span but much more expensive. Never measured time of life vs. money between the two. Good battery overall.

Works great in my acoustic electric and great value for total tech memvers

These Energizer MAX 9V batteries deliver long-lasting power, perfect for my smoke detector and other uses. A bit pricey, but worth it for the quality. Highly recommend!

Thank Goodness that we had a spare when the old battery in the garage door keypad went dead. We were able to buy these & have them delivered for free. What a time-saving deal!

Those batteries are great specially for important items like smoke detectors to use with, trust and durability to keep them on mind

Among the longest lasting 9 volt batteries I've ever used.

These batteries last longer than the rest. Energizer is my go to battery.

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!

I use these for my acoustic electric guitar and haven’t had to change batteries in months. Best batteries for long term playing.

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