When you run a SureFire weapon light or flashlight, the battery matters just as much as the light itself. These SF123A lithium cells are built to feed high-drain gear, delivering a full 3 volts and 1,550 mAh of capacity so your light hits its rated brightness and holds it. Lithium chemistry keeps the voltage steady through most of the discharge, which means you get consistent output instead of a slow dimming fade like you'd see from a cheap alkaline. This particular listing is a 12-pack clamshell of non-rechargeable cells, enough to keep multiple lights fed or to stash a backup supply.
The big draw here is longevity. These cells carry a 10-year shelf life, so a pack tucked into a range bag, glovebox, or emergency kit will still be ready to go years down the road. They also handle a wide temperature range, running dependably whether you're out in summer heat or hunting in freezing cold. Each cell weighs in around 17 grams and packs 4.65 watt-hours of energy, giving you serious power density in a small button-top package.
SureFire designed these to optimize the performance of their own lights, and they're built with fault protection that shuts the cell down if it overheats, an important safeguard when you're stacking two cells in series inside a light. That said, the 123A format is a standard, so these will run in any device that takes a CR123A, from tactical flashlights to older film cameras and light meters.
SureFire manufactures the SF123A in the U.S.A. to their own specs, which is a big reason folks who run SureFire lights stick with the matching batteries. If you count on your light in the dark or on duty, feeding it quality cells is cheap insurance for reliable output every time you hit the switch.
No, these are non-rechargeable primary lithium cells meant to be used and replaced. If you want a rechargeable option, you'd need to look at a rated rechargeable CR123A or an 18650 setup, though SureFire designs these disposable cells specifically for reliable, ready-to-go power. Their long shelf life is a big part of the appeal for cells you stock and store.
Yes. The 123A format is a standard CR123A size, so these will run in just about any device that accepts a CR123A, including tactical flashlights, cameras, and light meters. SureFire optimizes them for their own lights, but they perform well across the board in high-drain gear.
SureFire rates these cells for a 10-year shelf life, retaining a strong portion of their charge even after years on the shelf. That makes them a solid pick for emergency kits, go-bags, and backup supplies where you need power to be there when you finally reach for it. Runtime in actual use depends on your light's output setting and how hard you run it.
Yes, SureFire builds in fault and short-circuit protection that shuts the cell down if it overheats. This is an important safeguard, especially in lights that run two cells stacked in series. It's one of the reasons folks running SureFire lights tend to stick with genuine SureFire cells.
