CR123A

CR123A is a cylindrical lithium primary battery used in a variety of compact devices. It belongs to the CR123 family and measures about 34.5 mm in length and 17 mm in diameter. The nominal voltage is 3.0 volts.

Chemistry and form: The typical CR123A uses lithium manganese dioxide (LiMnO2) chemistry, offering high energy density and a long shelf life. It is a non-rechargeable cell designed for single use.

Performance: At low discharge rates, typical capacity is around 1,400 to 1,600 milliampere-hours, but capacity falls at higher drain. The cell maintains performance in a wide operating temperature range, commonly from −40 °C to about 60 °C, with optimized performance in cool to moderate climates. It has a strong energy-to-weight ratio and is lighter than many nickel-based cells.

Applications: Widely used in digital cameras, flash units, security sensors and alarm panels, as well as high-drain flashlights and other compact devices. The 3V output makes it suitable for devices designed for lithium primary cells.

Variants and safety: The term CR123A is often used interchangeably with CR123 and DL123/EL123 markings. The standard CR123A is non-rechargeable; attempting to recharge can cause leakage, venting or rupture. Store in a cool, dry place and recycle according to local regulations.
