great battery............................huge.............best battery ever.........never been a better battery ever.

These batteries last a long time in my Smoke Detectors and other such devices. No issues with corrosion! I trust Energizer Max Batteries to give me service.

Works well and the price was worth them. They were in stock.

I used this in my CO2 detector, and I think it lasted over 2 years.

Best batteries I have ever used. Never fail to properly operate my controllers

You can always count on Energizer batteries. They’re the best.

I've had the best performance from Energizer batteries over the years, so they are what I use exclusively unless I can't get them for some reason. And these came at a great price with my Best Buy membership!

These are really good batteries and last very long

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.

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.

Did exactly what was expected. Stopped the beeping from my smoke detector immediately.

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.

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

The batteries are durable and long lasting. The batteries are priced good.

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

We have the rather old Kidde model i4618AC smoke alarms in our house, but they require 9-volt batteries and we were running rather really low on them.

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!

Always reliable. Long lasting. Good price. Would buy again.

These are the only batteries that have never failed me. I use several types of wireless audio systems and digital equipment that are all battery operated and Energizer batteries always work better than every other battery I have tried. I have tried several other brands, which do not perform nearly as well a Energizers. Energizers seem to last so much longer.
