CR123A Batteries

Shop our collection of high power CR123A 3V lithium batteries, built for high-performance electronics like flashlights, security systems, and digital cameras. These compact power cells feature a 34.5mm x 17mm (2/3A) form factor and use LiMnO₂ chemistry to deliver stable, long-lasting energy.

What Makes CR123A Batteries Unique?

Voltage & Chemistry: Delivers 3V using reliable lithium manganese dioxide (LiMnO₂).
Primary Cell: Non-rechargeable with high energy density and a long shelf life - 10 years typically.
Standard Form: Usually button-top, ideal for high-drain devices like flashlights, photographic equipment, and alarm and security devices.
Backup Power: Two CR123A batteries can substitute for an 18650 in some flashlights with compatible housing - be sure to read your owners manual for compatability.

Battery Naming Explained

“CR” refers to lithium chemistry (LiMnO₂), and “123A” indicates its 2/3 A-size dimensions. Other labels like EL123A, DL123A, K123LA, and CR17345 are often interchangeable, depending on the manufacturer.

Rechargeable Alternatives

Yes, RCR123A or 16340 batteries are the rechargeable equivalents. These typically run at 3.6–3.7V, are slightly shorter (16mm), and have lower capacity than standard CR123As. Compatibility varies, so always check device requirements before swapping.

18650 Compatibility

Some devices designed for 18650 batteries can also run on 2 x CR123A batteries, provided they allow for different battery lengths and widths. A battery sleeve may be required for secure fitment. Compatibility varies, so be sure to check your device requirements before swapping.
