No, you cannot use a CR123 battery instead of a 16340 battery due to voltage differences. The CR123 operates at 3V, while the 16340 operates at 3.6-3.7V. Using the wrong battery can damage your device, so always check compatibility first!
Using a CR123A battery instead of a 16340 battery is generally not recommended due to several key differences between the two, despite their similar physical dimensions. Here’s a detailed breakdown of the factors to consider:
Size and Compatibility
- Both the 16340 and CR123A batteries share similar dimensions, with the 16340 measuring 16mm in diameter and 34mm in height, while the CR123A is slightly larger at 17mm in diameter and 34.5mm in height. This means that a 16340 can fit into a device designed for a CR123A, but the reverse is not true due to the larger diameter of the CR123A.
Voltage Differences
- The most significant difference lies in their voltage:
- 16340 Battery: Typically has a nominal voltage of 3.6V to 3.7V, which can rise to 4.2V when fully charged.
- CR123A Battery: Operates at a nominal voltage of about 3.0V.
Due to this voltage difference, using a 16340 battery in a device designed for CR123A could potentially damage the device if it is not rated to handle higher voltages.
Chemistry
- The chemistry also differs significantly:
- 16340 Batteries: Utilize lithium-ion chemistry, making them rechargeable.
- CR123A Batteries: Use lithium manganese dioxide chemistry, which is non-rechargeable.
Attempting to recharge a CR123A battery can be hazardous, as it is not designed for that purpose.
Capacity
- In terms of capacity:
- 16340 Batteries: Generally have lower capacities ranging from 500mAh to 1000mAh.
- CR123A Batteries: Typically offer higher capacities around 1400mAh, providing longer run times in devices that require it.
Interchangeability
While it may be tempting to substitute one for the other due to size compatibility, it’s crucial to check your device’s specifications. Some devices may explicitly allow for the use of rechargeable batteries like the 16340, but many are designed specifically for the lower voltage of CR123A batteries.
Conclusion
In summary, while you can physically fit a 16340 battery into a device designed for a CR123A battery, doing so is not advisable unless the device specifications explicitly allow it. The differences in voltage and chemistry can lead to performance issues or even damage. Always consult your device’s manual or manufacturer’s guidelines before making such substitutions.
