This makes them ideal for devices that require consistent performance over extended periods, such as digital cameras used during events or outdoor adventures.

Shelf Life

The shelf life of a battery is an important consideration, especially if you don’t frequently use the device it powers.

  • 123 Batteries: These batteries have a longer shelf life compared to 123A batteries. If you have devices that are not used frequently or have prolonged periods of inactivity, opting for 123 batteries can ensure they remain ready for use when needed without the need for frequent replacements.
  • 123A Batteries: While 123A batteries may have a slightly shorter shelf life, they make up for it with their superior performance and discharge rate. If you have devices that require constant usage or have a high energy demand, these batteries are the ideal choice to ensure optimal performance.

In summary, the choice between 123 and 123A batteries ultimately depends on the specific needs of your devices. If capacity, discharge rate, and longevity are your primary concerns, 123A batteries are recommended for their superior performance and sustained power delivery. However, if a longer shelf life is more important for devices that aren’t frequently used, 123 batteries provide a reliable option. Evaluate your device requirements and prioritize accordingly to make the best choice for your electronic devices.
