SUREFIRE SF123A BATTERIES 12PK

Description

SureFire’s CR123A lithium cells are purpose-built for high-drain devices — flashlights, weapon lights, and similar equipment that draw current faster than standard alkaline chemistries can sustain. Where an alkaline cell sags under heavy loads, the lithium formulation maintains a steadier output voltage throughout its discharge cycle, which means your light performs consistently from the first use to the last rather than dimming gradually as the battery depletes.

The 3-volt output at 1,550 mAh gives these cells the energy density to run compact, high-output lights without the bulk of larger battery formats. That combination of small physical size and high capacity is what made the CR123A format a standard in both professional and personal lighting equipment. SureFire rates these at a 10-year shelf life, which makes them practical to stockpile for emergency kits, go-bags, or any application where batteries sit unused for extended periods and need to be reliable on first draw. Wide temperature tolerance — a characteristic of lithium chemistry generally — also means performance holds up in cold conditions where alkaline cells lose capacity quickly.

This 12-pack carries part number SF12-BB and is manufactured in the United States using domestic and imported materials. SureFire produces these cells specifically optimized for their own flashlight and weapon light lineup, though they function in any device rated for the CR123A format. At 17 grams per cell, they add minimal weight to a kit even when carried in quantity.
