Yes, a 16340 battery is essentially the same as a CR123A battery in size (about *16mm x 34mm) and voltage (around 3V). They are interchangeable in many devices, but always check your device’s requirements to ensure compatibility!
The 16340 battery and the CR123A battery are often confused due to their similar sizes, but they are not the same. Here’s a detailed comparison highlighting their differences:
Size and Dimensions
- 16340 Battery: Measures 16mm in diameter and 34mm in height.
- CR123A Battery: Slightly larger, measuring 17mm in diameter and 34.5mm in height.
Chemistry
- 16340 Battery: Typically utilizes lithium-ion chemistry, which allows it to be rechargeable.
- CR123A Battery: Generally uses Lithium Manganese Dioxide, making it a non-rechargeable primary battery.
Voltage
- 16340 Battery: Has a nominal voltage of 3.6V to 3.7V when fully charged, reaching up to 4.2V.
- CR123A Battery: Operates at a lower nominal voltage of 3.0V.
Capacity
- 16340 Battery: Usually has a capacity ranging from 500mAh to 1000mAh.
- CR123A Battery: Typically offers a higher capacity, around 1400mAh, but is non-rechargeable.
Interchangeability
While the 16340 can physically fit into devices designed for CR123A batteries due to their similar dimensions, the differences in voltage and chemistry mean that they are not always interchangeable. Using a 16340 battery in a device designed for CR123A could potentially damage the device if it cannot handle the higher voltage.
Conclusion
In summary, while the 16340 and CR123A batteries share similar sizes, they differ significantly in chemistry, voltage, and capacity. The 16340 is rechargeable and provides higher voltage, whereas the CR123A is a disposable battery with lower voltage. Always check your device’s specifications before substituting one for the other to avoid potential damage.
