Customer Ratings & Reviews

I'm always needing various batteries for all the gadgets in the house. 9v batteries are the one I never think of, but always need. Recently, I needed to replace my smoke detector batteries, and I'm glad these are sold in a 4-pack. I like that it comes in a big 4-pack, so I don't need to buy a bunch of single 9v batteries. I also really like that these are Alkaline. They seem to last longer than the cheapest non-alkaline batteries. I'm definitely going to consider these again when I need to stock up on 9v batteries next time.

Good batteries, used in smoke detectors and garage door key pad.

Battery actually last a 48-Minutes longer than Duracell with our guitar amp!

The best batteries ever. Always use this brand for 9 volt power. Smoke Detectors, CO Detectors & Water leak Detectors too!

I got this product for a few things that use this product and they will come in handy and they will be helpful for the items that they will be used for

Quality battery power for music accessories. Works competitively with competitor brands.

Very good product. I will buy it again. Thanks! Good battery

[Employee of bestbuy] Great! Works like I just expected. Highly recommended!

Produces juice and I like the veddy veddy nice you will too Sammy

Good price. Solid value. The packaging could be better as it is broken but battery tested new

The beauty of these batteries is the price point. They last nearly as long as the name brands, but cost significantly less. I use these as back ups for two alarm clocks during power blips and outages and they last for years in this low power usage environment. No more blinking on 12:00!

I needed just one 9-volt battery for backing-up the memory of my telephone answering "machine." Closest was a CVS store, which had them at $10.29 for just one of the store's brand. I bought a card of FOUR batteries for $7.99 at Best Buy. I just can't imagine that the CVS battery was five times as good as the ones I got at Best Buy. I'll eventually find uses for the other three batteries. The only reason I gave it four stars instead of five is that I don't know how long a battery will last. If these are as good as Duracell or Energizer, the rating will have to go up to five full stars. Maybe with an added exclamation point.

I like these batteries and have gotten them before. They seem to last quite awhile. Four Batteries cheaper than 2 name brand and probably last longer than them. No complaints with them.

I got these to replace the batteries in my guitar pedals. They work well and I am happy with them. I also like the Best Buy essentials line. Seems to be great value for everyday products.

Works as expected, detail description and shows when it expires.

I buy the Best Buy 9 V batteries for my smoke detectors. The do just as good of a job as the Energizer batteries. They're also a good value, can't go wrong with the BB batteries.

Excellent purchase and value. I needed some 9v batteries and these were certainly better priced than name brand. And, they are working great! Recommend.

These are regular batteries with a decent life and a good price.

Perfect as intended. Good life span and great price. Definitely worth your money rather than paying for overpriced batteries.

These worked great in our home. They last a good amount of time and easy to use. I would buy them again. good price
