CR123 and CR123A batteries are essentially the same 3-volt lithium manganese dioxide cells with nearly identical size, chemistry, and performance. The two terms are used interchangeably by manufacturers. Differences mostly arise when comparing these primary batteries to their rechargeable versions. Choosing between them should focus on device requirements, brand quality, and battery type rather than the label.
What Are CR123 and CR123A Batteries and How Are They Defined?
CR123 and CR123A refer to the same type of lithium primary battery commonly used in high-drain devices such as security cameras, tactical flashlights, and medical equipment. “CR123A” is the more precise industry standard designation, while “CR123” is often used informally or as a shorthand. Both feature lithium manganese dioxide chemistry and provide a nominal voltage of 3 volts.
Are CR123 and CR123A Batteries Identical in Size, Chemistry, and Voltage?
Yes, both battery types share the same physical dimensions, approximately 34 mm in length and 17 mm in diameter, with minimal brand-specific size variance. Both use lithium manganese dioxide chemistry, ensuring a nominal voltage output of 3 volts and suitable performance for high-current pulse demands.
How Do CR123 and CR123A Batteries Differ in Real-World Performance?
Performance differences between CR123 and CR123A batteries are negligible as they are the same battery type. Both maintain stable voltage output, have long shelf lives reaching ten years, and perform well in high-drain applications like flashes or LED devices. Minor claims of capacity or temperature tolerance differences are inconsistent across brands and largely inconsequential for typical users.
What Are the Key Differences Between Primary and Rechargeable CR123/CR123A Batteries?
Rechargeable batteries labeled RCR123A or 16340 resemble CR123/CR123A size but differ fundamentally. Rechargeable versions offer voltages of 3.6 to 3.7 volts, higher than the 3 volts of primary cells. They require compatible devices, as using rechargeable batteries in primary-only devices can cause damage. Rechargeable batteries provide the advantage of reuse but have shorter shelf lives and different charging needs.
Can CR123 and CR123A Batteries Be Used Interchangeably in Devices?
Because CR123 and CR123A batteries are the same, they are interchangeable in devices designed for these cells. However, the “A” designation should not be confused with rechargeable CR123A or 16340 cells, which are not interchangeable with primary cells and should only be used where explicitly compatible.

How Does Temperature Influence the Performance of CR123 and CR123A Batteries?
Both CR123 and CR123A batteries exhibit wide operating temperature ranges, typically functioning reliably from well below freezing up to elevated temperatures. Their chemistry provides stable voltage output across extremes, making them suitable for demanding environments such as tactical gear and emergency equipment.
What Factors Should Be Considered When Choosing CR123 or CR123A Batteries?
Choosing between CR123 and CR123A should be guided by device compatibility, cost, brand reputation, and whether a primary or rechargeable battery is needed. Trusted brands like Panasonic, Energizer, or Redway Battery ensure quality, safety, and consistent performance. Always verify device manuals before selecting battery types.
How Do Shelf Life and Self-Discharge Rates Affect CR123 and CR123A Battery Usage?
Both battery types offer low self-discharge rates and shelf lives up to ten years when stored properly. This makes them ideal for emergency devices or infrequent-use applications requiring long-term reliability without frequent replacement.
What Safety Precautions Should Users Follow with CR123 and CR123A Batteries?
Users should avoid mixing primary and rechargeable batteries, observe polarity correctly, properly store batteries away from moisture and extreme heat, and purchase from reputable manufacturers to reduce risks of leakage or failure. Disposal should follow local regulations to mitigate environmental impact.
How Do Brand Reputation and Quality Impact Battery Performance and Warranty?
Brand credibility significantly impacts the consistency, performance stability, and warranty support of CR123/CR123A batteries. Companies like Redway Battery provide cutting-edge lithium battery solutions backed by strong warranties and global support networks, ensuring users get the best experience and value.

Redway Battery Expert Views
“Redway Battery emphasizes the importance of understanding battery labels and chemistry to avoid costly mistakes in device compatibility,” states a Redway Battery expert. “While CR123 and CR123A are effectively identical, the surge in rechargeable alternatives requires consumer vigilance. Our advanced lithium batteries prioritize reliability and safety, backed by extensive warranties, to empower users navigating this complex landscape.”
Conclusion
In conclusion, CR123 and CR123A batteries are fundamentally the same primary lithium cells with interchangeable use and equivalent performance. Key attention should be drawn instead to correct battery type selection—primary versus rechargeable—and quality from trusted brands such as Redway Battery for assured performance. Temperature tolerance, shelf life, and device compatibility remain pivotal factors in battery choice, rather than nominal differences implied by the naming convention.
