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 80°C, or -76°F to 176°F), 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 maintains fairly constant voltage for up to 95% of its life, depending on discharge rate. At moderate to high discharge rates, alkaline battery voltage drops rapidly due to internal battery resistance, which wastes power. The large reaction area provided by a lithium battery’s wound-plate construction provides very low internal resistance, ideal for high current loads.

SureFire illumination tools are the finest in the world — compact, rugged, powerful, reliable, efficient. Engineered for maximum performance and precision manufactured, they produce optimal beams — brilliant light with no rings, hot spots, or shadows. That’s why people whose lives may depend on having enough light when they need it, such as military, emergency, and police personnel and outdoors professionals, rely on SureFire.

SureFire Torches is a Southern California based company that produces precision tactical flashlights commonly used in the law enforcement and military fields. SureFire flashlights are also popular in the civilian market for personal, occupational, and self-defense purposes. The lights are often seen in TV shows and movies, such as the television show CSI.

SureFire produces flashlights of widely varying sizes and power outputs. These range from the tiny Titan to the hand-held M6 Guardian. Surefire also produces military weapon lights such as the Hellfire weapon-mounted searchlight for the M2HB machine gun or Mk 44 Minigun. One of SureFire's most popular products is the 6P Original. It is roughly the length of a an AA Maglite Mini-Mag, but produces twice the output of a typical three D-cell incandescent flashlight. The Z2 tactical light, which has similar performance, is standard issue to the FBI and U.S. Marshals Service.

SureFire models range from single-cell xenon lights to a large 20-cell HID model (also available with a rechargeable solution). Models employing an incandescent bulb offer the option of a brighter bulb (albeit at the cost of reduced battery life). They also produce a line of LED flashlights which include features such as electronically-controlled power regulation (allowing them to run in both 6 volt and 9 volt bodies and with less battery power than necessary to light an incandescent bulb) and multiple levels of brightness. The company has moved from the Lumileds Luxeon LEDs to the more efficient Cree XR-E LEDs in some of the 2007 models. SureFire LED flashlights often have improved run time versus their incandescent lights of similar output

Most of the Surefire Flashlights are powered by lithium CR123A batteries that allow for compact size and low weight while offering high power output. SureFire produce their own brand of CR123As. Some of the flashlights are available with rechargeable battery packs.

SureFire torches and flashlights are primarily made of aluminum, usually mil-spec type II or III hard anodized finish in various colors. Some less expensive models are made from Nitrolon, a proprietary impact-resistant, non-conductive, glass-reinforced polymer.
