SureFireSureFire SF123A Lithium Batteries, 48-Pack

These batteries are genuine SureFire SF123A 3v cells of recent manufacture in the USA, expiration dates 7/2029 indicating a full 10 year shelf life. The batteries and boxes were clearly genuine. The final proof of authenticity was in the performance; I use the batteries primarily for high output, high drain SureFire flashlights and headlights and they last far longer than any other brand I have tried. One must realize that these batteries don't last an extremely long time compared with alkaline batteries used in low draw applications, but that is to be expected and they performed to my expectations for genuine SF brand batteries. Also. The price per battery can't be beat.

I have tried other brands of CR123A battery's, but none give me the performance and dependability of Surefire. Without question these are the best battery's you can put in your high performance flashlight.

..but was one year out of the 10 into the expiration, so 9 years left isnt bad. When spending this much fir these little buggers youd hope for more life also especially as im stocking up for a shaky looking future, but i need these for a growing list that runs these little buggers. Prepping sure aint cheap!

I buy these for my Arlo and flashlights. Flashlights last forever, but the Arlo really eats the juice to point that i replaced it all with a Blink XT system. So I wont be purchasing these much anymore. Either way, this is a well made product, comes in little boxes, well packaged, well labeled. I priced these at a local Fred Meyer and found that they charge a ridiculous $70 for 8. So this price on Amazon is amazing!

Always a Surefire battery guy and have always been extremely pleased until this purchase. These only lasted 30-50 percent of what they normally do. Were they sitting on a shelf to long? Did they get to hot or to cold for too long during shipment? I don't know but it may have something to do with buying the 72 pack. Maybe those sit on a shelf longer. Just a bit disappointed.
