Customer Ratings & Reviews

I have the latest August smart lock that uses these batteries. I used to buy the batteries on Amazon but these are much cheaper and they are delivered by Best Buy the same day. Last just as long as the more expensive batteries do you can't beat that.

Good batteries for our August smart home lock. This pack is not too large, and the price is still decent. I wish it was slightly cheaper, but otherwise the Energizer batteries have worked well in the past.

Great product we love it good for camera and other electric things

battery has been working well. it was easy to install.

Great batteries, great price…. I will definitely buy these again.

Great value for what you get. I typically use them in all my handheld lights and weapon mounted lights

I hate the 123 battery system. But when you get it for half off stock up! These batteries last a long time and work wonders in my tactical flashlight. Highly recommend.

Energizer batteries are hard to beat. Home security is the application, Energizer is the solution.

These batteries last long, no complaints with its functionality at all. Only reason for 4 stars is its price. I use these in my flashlight. I use my flashlight pretty often when I'm out going for my walk/run in the evenings. If you don't mind the price, these are awesome. But if you're using these to power up something that you use pretty often and may need to change batteries often, maybe opt for something with batteries less expensive.

Needed these for a night vision hunting IR. They last longer than my rechargeable power bank for the scope.

Long shelf life is important for these batteries. They are used in smoke alarms, and only provide backup for when the power is out. The smoke alarms are in a place that is hard to reach, and we only have to change them a few times per decade.

This seller has great quality products and ill buy from this seller again thanks

Great batteries and with a 6pack, they should take care of my battery needs for 3 years

They're batteries that fit into a security motion detector. They fit, they work, they dance around in the middle of the night wearing my neighbor's underwear.

The batteries are very similar to Duracell but at much lower price. Great performance.

Great product for ring alarm sensors, last lot of time

I bought this two-pack set Energizer 3V 123 lithium batteries to power my remote Davis Weather station.I needed a reliable battery because it is mounted on a mast and difficult to change. Consequently I look for a product that will hold up for an extended period. These seem to hold up as good or better than most batteries of this type.

These are the batteries that make our home security system panel work. The last time I replaced batteries was about 2 1/2 years ago, so these have a long use time which is a big plus since you want your electronics to work, and these are kind of expensive, but worth it

10/10. Always use energizer batteries because of the quality. They will never let you down and stop working in the middle of a project. I miss when batteries had a gauge on the side that let you check the battery life

I use these batteries in my home alarm system. They are great and last for three to five years.
