Panasonic CR123A Lithium 3V Photo Lithium Batteries (4 Pack)

Good Lithium batteries! Arrived quickly and packaged well at a fair price! Perfect for my alarm sensors! I would buy again!

Needed for my fire alarm and works amazing!

Works great with my electrical devices. No problem at all.

These batteries are expensive. But they’re the size that I need, and they work well, with a decent life.

The batteries are just as expected for Panasonic!

Only a few uses. On handy when I had need for it

Exactly what and when I needed it

Great batteries for Ring Security System. Thanks

Good product

These batteries came packaged very nicely. They were caring enough to package it with a small piece of Styrofoam between the battery's to prevent shorting out during shipping. The price on these batteries is fantastic, although they do get cheaper the more you buy. Incase you didn't already know I'll let you in on a little known secret, these batteries are what the Canadian military uses and I know this for a fact as I have a family member in the military who confirmed this for me after I read it somewhere online and wanted his thoughts I regards to the truth on that. For me I personally bought these for the Olight Baldr Pro and I was very worried because the light has a turbo mode which needs a high power battery. This did the job phenomenally. One tip though, the Olight uses their own proprietary batteries which are sized a few millimeters smaller than these because they want you to buy from them. There are many videos on YouTube or just Google that explain how there is a tiny little rubber washer inside the battery compartment which you can remove with a tiny pair of tweezers or something similar and then you can use any 3rd party batteries such as these fantastic panasonic batteries. Also I suggest you stock up if it's for the Olight because it goes through batteries very fast, especially when used in high or turbo mode. So you might aswell buy a larger pack now since I've done the testing for you and can guarantee that these are compatible and all features will work as well as they do with the batteries it arrived with. Enjoy ;)

50/50 on this one; worked for one device but not for another. It came on time and helped me fix a battery issue for one smoke alarm device but then it didn’t want to work for another one in a different location of my house.

They last very long used on my August lock they go 3 months

Worked for job it was purchased for.
