The CR123A Battery: A High-Performance Lithium Power Solution
The CR123A battery (also known as CR17345) is a 3V lithium cylindrical cell prized for its compact size, high energy output, and reliability. Measuring 34.5mm in length and 17mm in diameter, it is slightly larger than the CR2 but maintains a familiar cylindrical “can-like” shape, similar to a scaled-down C-cell battery.
Key Features & Benefits
-
High Energy Density: Delivers strong, consistent power for demanding devices.
-
Long Shelf Life (Up to 10 years): Ideal for emergency equipment and infrequent-use applications.
-
Wide Operating Temperature Range (-40°C to +60°C): Performs reliably in extreme conditions.
-
Lightweight & Durable: Weighs around 16 grams, making it suitable for portable and rugged use.
-
Leak-Resistant Design: Unlike alkaline batteries, lithium CR123A cells minimize leakage risks.
Primary Applications
CR123A batteries are essential in:
-
Tactical & Military Gear (e.g., weapon lights, night-vision devices, laser sights)
-
High-End Flashlights & Outdoor Equipment (due to bright output and cold-weather performance)
-
Medical Devices (e.g., portable monitors, emergency tools)
-
Photography & Electronics (professional cameras, security systems)
-
Industrial & IoT Sensors (long-life power for remote monitoring)
Market Availability & Considerations
Due to their specialized use in critical applications, these batteries are highly sought after but can experience periodic shortages. They are produced by leading brands like Duracell, Panasonic, and Varta, as well as smaller manufacturers.
Buyer Tips:
-
Opt for reputable brands to avoid counterfeit or low-quality cells.
-
Check expiration dates, as lithium cells degrade over time despite their long shelf life.
