SureFire 123A lithium batteries are optimized for high-drain devices like tactical flashlights, weapon lights and optics. These are the same batteries SureFire uses to power their own lights, engineered to deliver consistent voltage output until they're nearly depleted rather than the gradual fade you get from alkalines.

The 10-year shelf life makes them ideal for emergency kits, vehicle stashes and backup supplies. Store them and forget about them until you need them. Wide temperature tolerance means they perform in extreme heat or cold without the degradation that kills standard batteries in harsh conditions.

Unlike alkalines that produce 1.5 volts and drop rapidly under load, these 3-volt lithium cells maintain steady output for up to 95% of their discharge cycle. High-output flashlights demand this kind of consistent power delivery. The higher energy density also means you get more runtime from a smaller, lighter package.

Built-in fault protection shuts the battery down if overheating occurs, preventing thermal runaway in demanding applications. Compatible with any device that uses CR123A batteries including SureFire, Streamlight, Modlite and other tactical lights.
