CR123A batteries are indeed more expensive than your typical AA or AAA batteries for a few reasons:

  • Lithium Chemistry: CR123A batteries are lithium primary (non-rechargeable) batteries. Lithium offers several advantages over alkaline batteries (like AAs):
    • Higher Voltage: They pack a higher voltage (3.0V) compared to alkaline batteries (1.5V), which can be beneficial for powering devices that require more power.
    • Longer Shelf Life: Lithium batteries generally have a longer shelf life than alkaline batteries, meaning they can stay unused for extended periods and still retain most of their charge.
    • Wider Operating Temperature Range: They can perform well in a wider range of temperatures, from very cold to hot environments.

However, lithium comes at a cost. Lithium is a more expensive material to manufacture compared to the materials used in alkaline batteries.

  • Specialty Battery: CR123A batteries are not as common as AA or AAA batteries. They are used in specific applications like:
    • High-powered flashlights and cameras
    • Medical devices
    • Laser pointers
    • Smoke detectors (in some cases)

This lower production volume compared to mass-produced AA and AAA batteries can contribute to a higher price per unit.

  • Limited Reusability: While some people attempt to recharge CR123A batteries, it’s generally not recommended by manufacturers. Improperly recharging lithium batteries can be a safety hazard. So, while they offer a longer shelf life, they are ultimately disposable batteries, adding to the cost per use compared to rechargeable alternatives like NiMH batteries.

In summary, the higher cost of CR123A batteries stems from their lithium chemistry, niche use cases, and limited reusability.
