No, you cannot use a CR2 battery in place of a CR123A battery. While both batteries share some similarities, including voltage and chemistry, their differences in size and capacity make them incompatible for most devices.
Key Differences Between CR2 and CR123A Batteries
1. Size and Dimensions
- CR2 Battery:
- Diameter: 15.6 mm
- Height: 27 mm
- CR123A Battery:
- Diameter: 17 mm
- Height: 34.5 mm
The CR123A is larger in both diameter and height, meaning it will not fit properly in a device designed for a CR2 battery.
2. Capacity
- CR2 Batteries: Typically have a capacity ranging from 600 to 900 mAh.
- CR123A Batteries: Generally offer a higher capacity, ranging from 1500 to 2500 mAh.
This significant difference in capacity means that CR123A batteries can provide power for a longer duration compared to CR2 batteries.
3. Voltage
Both battery types operate at approximately 3 volts, which is a similarity that often leads to confusion regarding their interchangeability. However, voltage alone is not sufficient for compatibility.
4. Application
- CR2 Batteries: Commonly used in compact devices like cameras and smaller electronic gadgets where space is limited.
- CR123A Batteries: Often found in high-drain devices such as tactical flashlights and security systems that require longer runtimes and higher power output.
Interchangeability Issues
Due to the differences in size and capacity:
- Attempting to use a CR2 battery in place of a CR123A can lead to poor electrical connections, potential damage to the device, or even safety hazards.
- Devices designed for CR123A batteries will not accommodate the smaller CR2 batteries securely.
Conclusion
In summary, while both CR2 and CR123A batteries are lithium-based and operate at the same voltage, their differences in size and capacity make them incompatible for use in the same devices. Always refer to your device’s specifications to ensure you are using the correct battery type.
Latest News
- The demand for lithium-based batteries continues to rise as more devices rely on portable power solutions.
- Manufacturers are focusing on enhancing battery technologies to improve performance metrics such as energy density and longevity.
- Sustainability initiatives are prompting more companies to develop recycling programs for used batteries.
