They say 10 year shelf life and they mean it. Took an some old ones out of my car that are stamped 10-2019. Ran a G2X on high and still got about hour; brand new ones are rated for 1.5 hours runtime. Years of hot and cold in the center console of my car and I can still count on them.

It is difficult to review batteries because longevity is what most people compare and all I know is the batteries are functioning in new condition. If the batteries quit working anytime soon, I will let y'all know

American made quality!

These batteries are great and very powerful.

NICE BATTERIES

Ive used Surefire CR123A cells in my Inova X5 and T1 flashlights for years without fail.Long lasting and high quality USA made Batteries.Expiration date on the batteries I received is 01-2024. Battery Junction shipped promptly at much cheaper cost than any other vendor I've purchased batteries from. Excellent products and folks at Battery Junction.

Surefire is a name brand battery, and at this price a great Value as well. I use SureFire batteries in all my SureFire lights, and weapon lights. I doubt I'd ever have an issue with warranty from them, however it's worth the slight increase in price to send them in with surefire batteries, no questions asked. These have worked every single time and never an issue. I highly recommend these.
