Worked really well for motion detector for ADT system,great value for money,lasts long,fit well and great power.Would buy again and would highly recommend.

Got these for my AED machine. They fit and last a long time. Want a name brand battery in something as critical as an AED.

Best batteries on the market! They last the longest of any batteries I’ve owned and will buy again.

I learned something that I didn't expect, I always use new Energizer batteries for smoke detectors and my alarm batteries. I have motion detectors and for some reason after about three months they needed to be replaced. So I installed another Energizer and the same problem. I called the alarm company and asked what the problem was and they suggested two other companies and one was Duracell so I ran to the store and bought Duracell and of course paid big bucks. So far it's been five months with no problems. I bought these for a back up at a much better price. I still can't believe that the Energizers didn't hold up. The alarm company was correct when they said Energizer don't last long in motion detectors. Very disappointed about Energizer batteries.

So I switched to these for my door lock after getting tired of constantly replacing the no name ones. These are twice as expensive, and they last around 5 months which isn't bad, but isn't much longer than the no name ones. I think those lasted around 4 months.

These Duracell CR123A 3V lithium batteries are exactly what I needed for my home safety devices and high-intensity flashlights. They provide long-lasting power and feel dependable for security cameras, motion sensors, and other home automation devices. I appreciate that the pack comes with 12 batteries, so I have plenty on hand for replacements. Duracell’s quality shows—no leaks, consistent performance, and they’re easy to store. If you want reliable batteries that won’t let you down, this pack is a great choice.

IDK what kind of review they're expecting out of me here but these are batteries. Batteries are exactly what I ordered. They are easy to use. I put them in the smoke detector. ImThe smoke detector stopped beeping. A win js a win! Hopefully they'll last for a long time. Like most batteries, I do wish they were cheaper because why are batteries expensive? But hey...you gotta have them, so you pay what you have to.

Good product and price
