    Use to purchase only Duracell. Found out Duracell was owned by P&G. Won’t bring any P&G products into my household so I gave Energizer a try. Great batteries. Long lasting in all my devices – mice, remotes, etc.

    So glad I found this battery at best buy for my smoke detector. Worked great. I went to other stores and it was out of stock. Best buy is good at replenishing their items.

    We use these in clocks, toys, and other things around the house. They always deliver great performance and last a long time. Price is comparable to other top batteries.

    I like being able to buy a long-life 9 volt batter battery in a two-pack. I don’t use a lot of them, but it is nice have a spare available when I need one.

    Choosing batteries is not something you should try to experiment with: try to save by buying unknown brands. Energizer and Duracell are equally good and I always buy them when I need batteries

    I always find that the Energizer batteries give me the best long-lasting batteries. These are 9-volts for those pesky smoke detectors that annoyingly chirp when the batteries need replacing.

    You can find cheaper batteries sure, but they will not be as good as Energizer. This company consistently delivers high quality batteries at a reasonable price.

    I like that the battery has a long shelf like. I like to keep one on hand in case the smoke detector battery starts chirping, this way I can replace immediately.
