    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.

    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!

    Not a Duracell, but a good battery for the price.

    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.

    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.

    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!

    I got these batteries because it was that time of the year to check the fire alarms/ Carbon monoxide detectors and I never buy the cheap batteries when it comes to me and my pet, I like Enegizer batteries they last long and because I was at Best Buy buying something else I pick these up.
