CR123A (CR17345) Battery

The CR123A (CR17345) is a cylindrical primary lithium cell in the CR series, built on lithium manganese dioxide chemistry at a nominal voltage of 3V. Its nominal capacity is 1,500 / 1,600 / 1,700 / 2,100 mAh (four variants), its size is 17.0 mm diameter x 34.5 mm height, and its reference weight is 16 g. Standard discharge current, cut-off voltage and test temperature are table values from the source specification table for this model, and should be read with those conditions in mind.

Cells of this type are used in security equipment, cameras and imaging accessories, medical devices, alarm systems, smoke detectors and industrial instruments — anywhere a compact 3V cell with a long shelf life is needed. The LiMnO2 line is stated to have a shelf life of up to 10 years and self-discharge of less than 1 percent per year at 20 degrees Celsius, with an operating temperature range from -40 to 85 degrees Celsius at category level. Those category figures explain why this chemistry is chosen for devices that sit unused for long periods and must work the first time they are needed.

Three characteristics define the CR cylindrical range. First, voltage stability: a nominal 3V output suits a wide range of compact electronics without additional regulation. Second, shelf life: up to 10 years at category level, so spares and installed cells alike keep their charge over long storage. Third, size coverage: the range spans small cells for handheld devices up to large cells for industrial installations, all on the same chemistry, which simplifies qualification when a product family uses several cell sizes. The model-specific figures in the table above are the values that apply to this model; category figures are not a substitute for them.

When selecting this model, confirm the capacity variant required, the continuous and pulse current the device actually draws, and the operating temperature range at the installation site. Where the source table lists several capacity variants for one model, all variants are shown in the table above, and the variant should be confirmed at ordering. Where a catalogue title mentions a capacity that the specification table does not list, this site does not present it as a specification value. Minimum order value is USD $500, according to the company FAQ, and samples are available. Lead time is confirmed per order. Certificates are available upon request.

The CR cylindrical range around this model covers a wide span of sizes, from small cells for handheld devices up to large cells for industrial installations, all on the same 3V lithium manganese dioxide chemistry. A compact device may use CR2, a camera or security device may use CR123A, and a long-life industrial installation may use CR26500 or CR34615, with the same voltage and the same handling rules across the range. Keeping one chemistry across a product family simplifies qualification, stocking and documentation, because the voltage, the storage rules and the certification names stay the same while only the size and capacity change. When a product family is planned, mapping every device to its CR size early avoids late redesigns of battery compartments and holders.

Storage and handling for CR cells follow the same rules as for other primary lithium cells. Store cells cool and dry, in their original packaging or in trays that prevent terminals from touching each other or metal objects, and keep them within the stated temperature limits. A short circuit during storage can damage a cell and create a safety hazard, so damaged packaging should be checked before use. Cells that are swollen, leaking or physically damaged should not be installed, and should be disposed of through the proper channel for lithium cells. For transport, UN38.3 test documentation applies to the cell design, and shipping arrangements are confirmed per order, with air freight or sea freight stated as the available options.
