Replacement Lithium 3v-cr1/3n Batteries

The Replacement Lithium 3V-CR1/3N Batteries from Truglo are essential power sources for modern tactical optics and illuminated firearm accessories. These compact lithium cells deliver the consistent voltage output required by red dot sights, laser designators, and electronic aiming devices used in law enforcement and military operations. For professionals and serious marksmen who depend on battery-powered optics in the field, having quality replacement batteries on hand is non-negotiable—downtime means reduced operational capability.

Lithium 3V chemistry provides superior performance characteristics compared to standard alkaline alternatives, including extended shelf life, reliable output in extreme temperatures, and higher energy density. The CR1/3N cell size is the industry standard for compact tactical optics, offering steady 3-volt discharge across the battery's functional lifespan with minimal voltage sag under load. This stability is critical when using battery-dependent sighting systems, as voltage fluctuations can cause reticle dimming or electronic drift that compromises sight picture and accuracy during critical moments.

Field professionals should stock Replacement Lithium 3V-CR1/3N Batteries as part of routine equipment maintenance for Truglo red dot sights, laser modules, and compatible illuminated optics platforms. These batteries are compatible with virtually all compact tactical optics using the CR1/3N format and maintain performance in temperature extremes from cold mountain environments to desert heat. For backup carry systems, duty rifles, and training equipment, a spare battery pack ensures your sighting system remains operational when needed most.
