Customer Ratings & Reviews

If everyone has a smoke detector and they use 9 volt batteries, why are they so hard to find. Thank you Best Buy for carrying one of the top brands too

Batteries from Energizer are very good, still keeping my smoke detector working!

These really are batteries and they really do work.

I needed good batteries for my smoke detectors and these work well

What can you say about a batterie. It works great sas advertised

You always need 9 V batteries in your house and these are the best to buy

These batteries are great, true most things are going bluetooth, etc.. and we won't need Duracel for much longer. But, I still use them now, everyday, in everything.

Energizer batteries are the best. This 2 pack is perfect, especially considering they are 9 volt. Not a lot need for these so a bigger pack would be extremely wasteful

These batteries hold their charge and perform for a longtime before needing replacement. The energizer bunny has plenty of energy!

The energizer max batteries 9 volt are just what i needed. My smoke alarm needed new batteries. Replaced them with these and it's back working great!

found 9 volt batteries easily, the price was very competive for the quality of the batteries i purchased, would purchase again when i need 9 volt batteries

I don't really know what to say about these batteries. They have a proven name for lasting. I have always had good luck with the Energizer brand.

Duracell is the best battery to purchase for anything that runs by battery...I always purchase Duracell over any other battery

Always put the best in my smoke detectors, one less thing to worry about.

Best batteries you could buy and Best Buy is the cheapest. you cannot find these batteries online for any cheaper, trust me I looked. Just buy them already!

as usually for "Energizer"-great quality for given price tag

always try to choose Energizer batteries they always seen the last better I'm a bigger fan of them then Rayovac so all is good when you get Energizer batteries

I had a big capacity Maytag for almost 25 years, so for me there was no question that I wanted a new Maytag, just HE and front loaded. I am so happy with my new machine, especially because it's so silent in spite of being so big! (I had to build out the laundry closet since the new one was 2 inches wider and like 5 inches deeper. But so are also most new washers). An advice: dry the lower part of the rubber seal with a dry cloth, since there's always some residual water there. And let the machine open for a while, so it dryers completely out.

I've tried a lot of different batteries in a wireless mic application, but finally I've settled on Energizer. Nothing lasts as long.

My smoke detector won't run on anything less than the power of an Energizer battery.
