Streamlight CR123A Lithium Batteries 6 Pack

I've been running these in my tactical flashlight for months without a single flicker, and the 10-year shelf life gives me peace of mind for emergency kits.

Installed these in my SureFire flashlight and they fired up instantly with full brightness. The ten-year shelf life is a nice bonus for emergency stash.

The six-pack means I always have spares stashed in my gear bag and glovebox, and these lithium cells hold their charge noticeably longer than the alkaline ones I used to rely on. They seat firmly in my flashlight without any wobble, which is exactly what I need when I'm reaching for it in the dark.
