CR17345 vs CR123A, Similarities and Differences
CR123A and CR17345 batteries are primary (non-rechargeable) lithium batteries, meaning they do not support charging cycles. Both are designed for single use and are disposed of after their energy is depleted. Therefore, there is no comparison in terms of charging cycles, as neither battery is rechargeable.
Here are the key details:
Similarities
Voltage: Both have a nominal voltage of 3.0V, making them suitable for high-drain devices like flashlights and cameras.
Chemistry: Both use lithium manganese dioxide (LiMnO₂) chemistry, which provides high energy density and stable voltage output.
Dimensions: Both batteries share identical dimensions—17 mm in diameter and 34.5 mm in height.
Capacity: The capacity typically ranges from 1400 mAh to 1700 mAh, depending on the manufacturer.
Applications: Both are used in high-drain devices like cameras, flashlights, and security systems due to their ability to deliver high-pulse and continuous currents.
Differences
While CR17345 and CR123A are often interchangeable, minor differences may exist depending on the manufacturer:
Brand-Specific Features: Certain brands may include additional features like PTC protection (over-current protection), which may be highlighted more prominently for CR123A batteries.
Labeling Variations: The designation “CR17345” is often used interchangeably with “CR123A.” However, some manufacturers may slightly vary their specifications under these labels, leading to minor differences in capacity or discharge rates
Capacity Variations: Some manufacturers list slightly different capacities for CR17345 batteries (e.g., 1400 mAh) compared to CR123A batteries (e.g., up to 1700 mAh).
Energy Density Comparison
- CR123A: Known for its high energy density, it typically offers up to 280 Wh/kg, making it suitable for high-drain devices like LED flashlights and cameras.
- CR17345: Also features high energy density, comparable to the CR123A. Manufacturers like Panasonic highlight its dependable performance and ability to deliver consistent power in compact devices
Capacity Differences
- CR123A: Capacity ranges from approximately 1550 mAh to 2500 mAh, depending on the manufacturer.
- CR17345 typically has a nominal capacity of around 1400 mAh, which is slightly lower than some CR123A variants
Conclusion
CR17345 is simply an alternate naming convention for the CR123A battery. They are functionally identical and interchangeable in most applications, with any differences being manufacturer-specific rather than inherent to the designation.
While both batteries share similar energy densities and are interchangeable in most applications, the CR123A may offer slightly higher capacity depending on the brand and model. However, any differences in energy density are negligible for practical purposes.
CR123A vs CR17345 batteries perform identically and can be used interchangeably in devices. Any differences are typically related to branding rather than inherent performance characteristics.
