There have been reported incidents of counterfeit and/or inferior-quality lithium batteries developing internal shorts that have led to fires and/or explosions. This has resulted in damage to the illumination tool and, in some rare cases, property damage and/or personal injury.

Customers are specifically WARNED against purchasing batteries from online-auction and other websites not authorized by SureFire, as these are known sources of counterfeit and/or inferior-quality batteries.

The use of counterfeit and/or inferior-quality batteries could greatly reduce runtime and output performance, damage your SureFire illumination tool, constitute a safety hazard, and may void SureFire’s No-Hassle Promise.

SureFire-brand batteries, and those rechargeable batteries sold directly by SureFire, are manufactured to strict quality standards specifically for use in high-performance, high-drain devices. All SureFire-brand batteries contain built-in fault and heat protection for added safety.

For these reasons, SureFire specifies that you purchase competitively priced replacement batteries from SureFire or an authorized SureFire dealer. Locate your nearest SureFire dealer here. That way, quality and safety are guaranteed while prices are kept low—typically far lower than the retail price of comparable or questionable-quality batteries—to accommodate the needs and safety of our valued customers.

SureFire performance claims are based on the use of SureFire batteries that initially ship with SureFire illumination tools.

You may also use batteries from well-known manufacturers such as Panasonic®, Energizer®, or Duracell® to ensure safe performance. These brands are registered trademarks of their respective companies.
