Normally I buy Surefire primary CR123a batteries, well aware that most of the big brand name CR123a cells are manufactured by Panasonic., but bought these Energizers this time to kick it's tires.To test these, I took two identical Surefire Invictus flashlights. I put in three Surefire cells in one and three of these Energizers in the other and set both magnetic control rings to one back-click from full power to see which battery lasted the longest. Over the years I've found this side by side test to be a good tell all to determine the best cell in the runtime department. (it is however a bit wasteful to waste six CR123a cells and put a bit of wear and tear on the lights themselves, but its not a performance test I run often, combined with the fact that Surefire uses a proprietary premium thermal interface material & proper heatsinking, it can be abused some. (I have a big tube of it in my shop, it's approved for NASA use as well) Surefire doesn't cut corners, and that's why their products are a bit pricey, but you can count on them when it counts.) In the end the performance run time of the Energizers was nearly identical to freshly bought Surefire primary batteries. I suspected this would be the outcome. I'd surely buy them again now that I know it's tit for tat with Surefire primary cells.   Read Less
