What's the Difference Between CR123 and CR123A Batteries?


The CR123 battery is identical to the CR123A battery, operating based on the Duracell lithium battery mechanism. The difference in designations arises from various manufacturers labeling their products differently. However, two different product samples will inevitably exhibit specific differences, and CR123 and CR123A are no different. Let's delve into a few metrics for comparison, offering you a comprehensive review.


Size


Both CR123 and CR123A batteries boast a compact design to deliver substantial power. Their small form factor, relative to the power they provide, makes them excellent choices for energy-demanding small devices, such as high-output LED lights.


Regarding physical dimensions, 123s are generally longer and thinner than 123As, albeit the difference is no more than 0.55 mm in either direction. The dimensions may vary slightly among manufacturers, adding to the challenge of distinguishing the two.


Compared to alkaline AA batteries (with an average length of 44 mm), both CR123 and CR123A batteries are considerably shorter while delivering twice the voltage. Two CR123s can yield 6V in a much more compact configuration than the 3V output from two AAs.

Both batteries share a comparable shelf life, extending to 10 years when stored below 60°C.


When incorporated into your devices, both exhibit prolonged durability. The specific lifespan varies based on the gadget and the manufacturer. For instance, they may endure for up to five years in an alarm system.


Voltage


Both regular 123s and 123As possess a nominal voltage of 3 volts. Their standard loaded voltage usually falls within the 2 to 2.5 volts range.


In essence, both cells have substantial potential to drive electric current through the device, particularly considering their compact size.


Generally, there is no notable distinction in voltage between the two battery types.


Chemistry


Both battery types employ a lithium-based salt as an electrolyte with a chemical system of Lithium and Manganese dioxide (LiMnO2). The cathode (positive terminal) consists of heat-treated manganese dioxide in both cell types.


The chemical system operates identically, providing a high energy density per mass (280 Wh/kg) and per volume (580 Wh/liter).


Note: Wh (watt-hour) is a unit measuring the battery's energy density. Wh per kg or liter gauges the battery energy per unit of mass or volume, respectively.


Safety


Lithium poses potential hazards, particularly on skin contact, and its high voltage can harm devices.


123s and 123As are equipped with PTC (Pressure, Temperature, Current) protection, interrupting the circuit if the current exceeds safe levels.


Operating Temperature


The primary difference between CR123 and CR123A lies in their respective operational temperature ranges. CR123 functions within the temperature span of -20 °C to 70°C, whereas its counterpart boasts significantly broader operating temperatures, extending from -40 °C to 70°C.


Performance Comparison


Energy Density


CR123A batteries exhibit a notable energy density, signifying their capacity to store substantial energy within compact packaging, resulting in prolonged power output.

CR123 and CR123A Name Meaning


Observing these two batteries, they appear similar. The primary distinction lies in the nomenclature, reflecting manufacturer preference. Some are labeled CR123, while others are designated CR123A. Including the letter A in CR123A signifies that the battery is two-thirds the size of a standard A-sized battery.

The initial two letters in CR denote lithium, and R indicates a cylindrical structure. The number 123 denotes the battery size, indicating it is two-thirds the standard length of a battery.


Hence, whether using a CR123 or CR123A battery, it can be considered a comparable type of battery.


Are CR123 and CR123A batteries the Same?


It's reasonable to assert that the primary distinction between the two lies solely in the presence of the letter A. When examining their functionality, performance, lifespan, and chemistry, they equate to the same thing.


Both batteries can support high-performance devices, including those with intermittent demands for substantial power output, such as digital cameras with flashes and advanced LED torches.


Each manufacturer assigns a distinct label to essentially the same type of battery. For instance:


  • Energizer –123

  • Rayovac — 123A

  • Duracell — CR123

  • Panasonic — CR123A


The dimension difference is so negligible that both batteries can be used interchangeably in all devices.


Are CR123 and CR123A Interchangeable?


While the specifications and dimensions may seem inconsequential, avoiding interchangeability between these two products is advisable. Why make such a recommendation?


Despite the slight length disparity between CR123 and its counterpart, inserting batteries into delicate devices can sometimes pose challenges. Additionally, CR123a is crafted explicitly for high-tech LED torches and digital cameras, a capability not shared by CR123.


In terms of voltage, the CR123 battery yields a higher voltage than its counterpart but falls short compared to the CR123A model. Consequently, intentional substitution can occasionally lead to performance issues in the equipment it serves.




CR123A Equivalent


EL123A, DL123A, 16340, CR17335 and RL123A can equivalent to CR123A.


  • 16340: The 16340 battery, a lithium-ion variant, matches the size and voltage of the CR123A. It serves as a substitute for CR123A batteries in specific devices. It's crucial to acknowledge that 16340 batteries are rechargeable, unlike the non-rechargeable CR123A batteries.

  • DL123: This lithium manganese dioxide battery mirrors the size and voltage of the CR123A. It can be freely interchanged with CR123A batteries in most devices.

  • EL123A: Another lithium manganese dioxide battery sharing a comparable size and voltage with the CR123A. It is a viable replacement for CR123A batteries.

  • CR17335: The CR17335, a lithium thionyl chloride battery, aligns in size and voltage with the CR123A. While interchangeable with CR123A batteries, it's noteworthy that CR17335 batteries are less common, making them challenging to procure.


How do you Know Whether the Batteries Need to be Replaced?


The diverse impact and maintenance approaches complicate pinpointing an exact timeframe for the longevity of the mentioned products. However, experts suggest that these battery variants typically endure for an average of three years before manifesting signs of wear and becoming non-rechargeable.


CR123 vs. CR123A Conclusion: Which One Should You Buy?


This article aims to provide a comprehensive and detailed comparison of the CR123 versus CR123A brands. While the disparity between these two products might not be substantial, its impact will undoubtedly manifest in the performance quality of electronic devices. Assessing and selecting the appropriate products rather than utilizing them interchangeably is advisable.


When evaluating CR123 and CR123A batteries, three key factors warrant consideration:


  • Examine the mAh, as a higher mAh tends to extend the battery's lifespan.

  • Assess the shelf life, mainly if some batteries remain unused for an extended period.

  • Factor in the price.
