DURACELLCR123A 3V Lithium Battery, 4 Count (Pack of 1), 3 Volt High Power for Home Safety, Security Devices, Flashlights, Smoke Alarms, Home Automation

I got these to replace the batteries in my ADT sensors. ADT was selling them for about 8x the price. Duracell is a great brand, long lasting, very reliable. I was happy to find the exact right match.

Very useful and a great product for the money.

Not much you can say about batteries. They worked and are still working and this was a great price.

Great item! Did exactly what I needed it to do. As described. Would purchase from this vendor again! Thanks!

I am replacing a Duracell Ultra (blue stripe in photo) from my home alarm remote door sensor that was installed on 11-8-07 (I wrote the install date on the battery) with this new Duracell (non-ultra). The one thing I noticed right away was that the writing was difficult to read on the new ones. Just very lightly printed. Used my phone to enlarge the text and can see Made in China. The Ultra from 2007 was easy to read and shows MADE IN U.S.A in bold print. It seems they are trying to hide the mfg location on the new ones. Well hopefully this one will last as long as the first one. I went with Duracell because the alarm sensor cover shows inside to use Duracell, Panasonic, or Sanyo. These were sold and shipped by Amazon so hopefully these are legit batteries.

Good value

Prefer brand name batteries. Just seems they last longer and less worries, particularly if you are changing batteries in a high or difficult location.

Not a battery I often need, but I did when the old ones were low in my Smoke/CO2 detector. I replaced and should be good to go for many more years.
