Understanding CR123A Battery Chemistry

CR123A lithium batteries use lithium manganese dioxide (LiMnO2) chemistry, which offers significant advantages over alkaline batteries for high-drain applications. Lithium batteries maintain higher voltage under load, provide more consistent power delivery, weigh less, and perform better in temperature extremes. The 3-volt nominal voltage of CR123A batteries delivers twice the voltage of standard AA or AAA alkaline cells, enabling more efficient power delivery to high-performance LEDs and electronics. SureFire's specific formulation optimizes current delivery for tactical flashlights that demand sustained high output, preventing the voltage sag that causes dimming in inferior batteries.

Compatibility

These SureFire SF123A batteries are compatible with hundreds of devices including: SureFire flashlights (all models using 123A batteries), Streamlight weapon-mounted lights (TLR-1, TLR-2, TLR-6, TLR-7 series), Fenix tactical lights, Olight flashlights, red dot sights and reflex optics, laser aiming devices, night vision equipment, camera flash units, home security sensors and wireless devices, medical equipment, emergency radios, and any other device specifying CR123A battery compatibility. Not compatible with devices requiring rechargeable RCR123A batteries unless the device explicitly supports both types.

What's Included

Ideal For

Perfect for tactical flashlight users who demand maximum reliability and performance. Essential for law enforcement duty weapons with weapon-mounted lights, military personnel deploying to extreme environments, emergency responders requiring dependable illumination, concealed carry holders with weapon lights, home defense firearms with mounted lights, vehicle emergency kits requiring long-term battery storage, bug-out bags and survival gear, backup power for critical devices, photographers using CR123A-powered equipment, and anyone requiring batteries that will remain fresh for years of storage. The 10-year shelf life makes these ideal for stocking emergency supplies, maintaining ready-to-go tactical gear, and ensuring backup batteries are always fresh.

Why Choose SureFire Batteries?

SureFire doesn't just make flashlights - they manufacture their own batteries specifically optimized for their lights and other high-drain tactical equipment. This vertical integration ensures perfect compatibility and maximum performance. Many tactical users report that SureFire batteries provide noticeably longer runtime and brighter output compared to generic CR123A batteries. The 10-year shelf life is backed by decades of real-world use in military and law enforcement applications where failure is not an option. While SureFire batteries cost more than generic alternatives, the extended shelf life, reliable performance, built-in safety features, and USA manufacturing quality make them the clear choice for critical applications. When you're depending on your light in a life-or-death situation, SureFire batteries provide peace of mind that generic batteries cannot match.

Storage and Handling

Store SureFire batteries in a cool, dry location away from metal objects that could cause short-circuits. The 10-year shelf life assumes storage at room temperature (approximately 70°F). Higher storage temperatures will reduce shelf life, while cooler storage extends it. Keep batteries in original packaging until use to prevent accidental short-circuits and contamination. Do not mix old and new batteries, or batteries from different manufacturers. Replace all batteries in a device at the same time. Never attempt to recharge non-rechargeable CR123A batteries - this can cause dangerous thermal events.

Battery Safety

SureFire CR123A batteries include built-in heat and fault protection for safe operation. However, always follow basic lithium battery safety: Never carry loose batteries in pockets with metal objects like keys or coins. Never puncture, crush, or disassemble batteries. Do not expose to fire or high heat. If a battery shows signs of damage, swelling, or leakage, do not use it and dispose of properly. Keep batteries away from children. For disposal, check local regulations for lithium battery recycling programs.
