Customer Ratings & Reviews

I use these batteries for my smoke detecteor. And they last for a couple of years. I didn't realize how long they lasted until I changed the last set and noticed they expired in 2015 and my smoke detector just started beeping indicating low battery power. BTW, I bought them in 2012.

Works great. Replaced a 6 year old battery, looking for 6 more.

great price on these batteries --you won't find cheaper Energizer batteries anywhere

I can buy sane batteries a lot cheaper elsewhere and I do. This was a “oh let me just grab them here” item Don’t be a fool like me; save yourself a bunch of money and buy them down the street or online…. Best Buy can make a profit but still put the price more reasonable!

As indicated in the manufacturer's description, this battery has a very long shelf life. I had a pack that was purchased about a year ago, and utilized recently for my backup emergency torch. After several months' use, it feels like brand new battery.

Bestbuy is the only place to buy batteries online. Anytime I've bought from sellers on other sites they send me batteries in a plastic baggy. These batteries arrived in the retail packaging and worked perfectly in my security cameras. Battery life seems to be longer too.

These last me for a long time with a good charge. Can rely on my lock to always have battery when i leave the house for a while.

Good purchase excellent price for these batteries for my flashlight. It had been lying dead for a while until I found the batteries at Best Buy.

Very dependable, worth the extra money. They last a long time, I used them for many different electronic items that I I have in my home. You pay a little more but, you get qualities service out of them .

These are great CR123 batteries from energizer. They do what they're supposed to do and don't leak, which is an issue I have had with other brands, especially Duracell. I was surprised and happy that Best Buy actually carried these as they are not standard.

these batteries are for a flashlight that requires these special batteries. they are used two at a time to give a very powerful light for the flashlight. Best Buy priced matched them for me online and they were cheaper than even Walmart.

I have better life from these lithium batteries than other brands, but generally the equipment that uses the CR123 batteries have pretty high power draw and I change them often, so it's nice that these come in a 12-pack

These batteries are so good. pricey sometimes. they last for a long time.

I got the 12 pack for a Great buy and they are holding up really good for my smart lock going on 2 months and still working. I’m sure it will be a while before I will need to repurchase more.

Not sure if its better than the insignia brands but wanted to trust these batteries a bit more than cheaper ends.

I was running short on time (impromptu trip to Minnesota) and I couldn't find these anywhere. I had to have them for my camera and I was afraid that I wouldn't be able to get them in time. I made a last minute decision to run to Best Buy and I found them!

Reliable product I use for my smart door, and it will last very long.

Energizers are as good as it gets the only thing about all of the brands it that they cost too much. If you need them you have to buy them.

I use in wireless smoke and carbon monoxide detectors in my home. Last a long time.

I use these batteries in my golf range finder. They work well and last a long time. I always keep a spare incase battery stop during a round. have never been disappointed with these.
