Surefire 123A CR123A 3V

SureFire Lithium batteries CR123A Batteries - Optimized for use in SureFire flashlights, SureFire Lithium batteries pack a lot of power into a small package. And unlike alkaline batteries SureFire High-Performance Lithium Batteries boast a ten-year shelf life, which means they will be ready when you need them, every time. Surefire non-rechargeable flashlights and weapon lights use these lithium batteries because of their advantages over alkaline batteries. These advantages are: Shelf Life At room temperature, lithium batteries can be stored 10 years and still supply about 70% of their power. Alkaline batteries have a significantly shorter shelf life. Temperature Tolerance Lithium batteries function over a wide temperature range (-60 to 80C, or -76F to 176F), although power is reduced at the extremes. In contrast, alkaline batteries function poorly below freezing and at higher temperatures. The temperature tolerance of lithium batteries also benefits their shelf life. Storing alkaline batteries at higher temperatures can kill them in a few months, but lithium batteries stored for years at similar temperatures can still function effectively. Power Density For a given size (volume), lithium batteries produce much more power than alkaline batteries. For example, given same-sized batteries and the same power load, it would take about 2.5 alkaline batteries to match the power output of one lithium battery. Weight For a given size (volume) lithium batteries weigh about half as much as alkaline batteries. For example, an alkaline battery the size of a SureFire SF123 battery would weigh about twice as much. Voltage Terminal voltage for lithium batteries is 3 volts compared to 1.5 for alkaline batteries. Voltage Maintenance A lithium battery maintai
