Batteries on a Rifle Mounted Light

I need some new CR123A batteries I am used to using surefire since I had a surefire LED light and I trust that brand but has anyone used that brand vs something else and gotten better results?

I’ve used Surefire and Energizer Cr123A batteries in my rifle lights. Haven’t really used them for long enough periods to notice a difference. I occasionally use them in one of my flashlights but I prefer to use a rechargeable battery in it so haven’t used them enough in that either to notice a difference.

I usually just go with whichever one of those I can find on sale.


I like Surefire and Panasonic CR123. I’m sure Energizer would be good too but they get pricey even for 123’s


Have had good luck with surefire and streamlight 123s, as well as duracell, energizer and panasonic. I avoid no name batteries in stuff my life may depend on. Amazon will run deals on the larger packs of streamlight batteries from time to time
