CR123A 3V Lithium Battery - Box of 50

I have used these in outdoor sensors for a couple of years. They are fairly long lasting and haven't leaked.Better than the cheaper ones

I use these in my thermal scope and they last approximately 5 hours running straight. They last me about three weeks if I run it off and on. I am very pleased with the batteries. They last longer than the Energizer ones and for a better price point.

They’re batteries. I can’t tell you the life for awhile, but they serve my purpose.

Battery Junction is great! Go direct to them to save $

Ok, batteries are a very difficult item to purchase. Ive literally tried 15 different brands, household names to never before heard of. These hands down have held the most charge per equal use period even over Duracell, Energizer. I'd say double to be honest and the price is great for these ridiculously expensive batteries.

I love these batteries. I use these for my edc flashlights and keep several in my truck for spares. These batteries have a great shelf life and they last a long time when using them in my flashlights. I keep several on hand for emergencies. The price on these cannot be beat! Thanks for a great purchase!

When I did research on lithium battery’s and found out they are all basically the same I started buying much less expensive ones and these work just as good as surefire, or any name other brand names, and I’ve used a lot of 123’s in my flashlights.

As advertised. Have used lesser (and a little cheaper) ones that don't last nearly as long as these.
