The CR123 and 16340 batteries are often confused due to their similar dimensions, but they have distinct characteristics that make them suitable for different applications. Understanding these differences is crucial for selecting the right battery for your needs.
Key Specifications
1. Size and Dimensions
- CR123 Battery:
- Diameter: 17 mm
- Height: 34 mm
- 16340 Battery:
- Diameter: 16 mm
- Height: 34 mm
While both batteries are cylindrical and share the same height, the CR123 is slightly wider.
2. Chemistry and Voltage
- CR123 Battery: Typically uses lithium manganese dioxide chemistry, with a nominal voltage of approximately 3.0V.
- 16340 Battery: A rechargeable lithium-ion battery, usually with a nominal voltage of 3.6V to 3.7V. Fully charged, it can reach up to 4.2V.
3. Capacity
- CR123 Batteries: Generally have a capacity of around 1500 mAh to 1600 mAh, depending on the brand and specific model.
- 16340 Batteries: Typically offer lower capacities, ranging from about 550 mAh to 900 mAh, which is about 40-50% of the capacity of a CR123 battery.
Rechargeability
- The CR123 battery is a primary (non-rechargeable) battery, meaning it is designed for single use and should not be recharged.
- The 16340 battery is rechargeable, making it more cost-effective in the long run if used in devices that support this type.
Performance Characteristics
1. Applications
- CR123 Batteries: Commonly used in cameras, flashlights, and security systems where long shelf life and stable voltage are essential.
- 16340 Batteries: Often found in high-drain devices such as tactical flashlights and vaping devices due to their higher voltage output.
2. Voltage Compatibility
Devices designed for CR123 batteries may be able to accommodate 16340 batteries; however, the increased voltage may not be suitable for all devices. It’s essential to check the manufacturer’s specifications before substituting one for the other.
Cost Considerations
- CR123 batteries are generally less expensive per unit than 16340 batteries; however, since 16340 batteries are rechargeable, they can save money over time if used frequently.
Latest News
- The demand for rechargeable batteries like the 16340 is increasing as consumers seek more sustainable options in electronics.
- Innovations in battery technology are leading to improved performance metrics for both CR123 and 16340 formats.
- Manufacturers are focusing on eco-friendly production practices and recycling initiatives for lithium-ion batteries.
