CR123A, CR1 and CR2 batteries provide reliable and long-lasting electricity.
Cylindrical lithium batteries, such as CR123A, CR1, and CR2, offer unsurpassed energy density and the ability to provide a stable 3V voltage at extremely high pulse loads. The lithium-based chemistry allows these cells to function in a wide and extreme temperature range, making them the primary choice for professional tactical flashlights, laser sights, high-resolution cameras, and smart home sensors. The CR123A model stands out with an impressive 1500mAh capacity, ensuring a long standby time. Minimal self-discharge guarantees their reliability even after several years of equipment storage.
Physical and technical parameters:
- Lithium chemistry: High voltage and huge discharge current for optical devices.
- Long standby: Low self-discharge allows storage for years without loss.
- Extreme temperatures: Works flawlessly even in frost and high heat.
Lithium primary cells exhibit maximum energy efficiency, making them irreplaceable in professional equipment. Due to stable output, they are ideal when using everyday carry Mini LED Flashlights. Safety standards require the use of only certified elements in work technologies. Properly selected components that meet technical specifications significantly extend the operating cycle of the hardware in extreme working conditions. Integrated materials engineering and rigorous quality control during the manufacturing process ensure maximum reliability and safety in all application scenarios. This approach is fundamental to today's demanding industrial and professional needs, where there is no room for error. Efficiency is always a primary requirement for any system.
Q: What are the main technical advantages of CR123A and CR2 lithium (3.0V) batteries in outdoor sensors and cameras?
Q: Why are CR123A lithium batteries specifically used in wireless security and motion sensors (such as Ajax or Eldes)?
Q: What is the difference between a single-use CR123A (3.0V) battery and a rechargeable RCR123A / 16340 (3.7V) accumulator?
Q: Why are CR2 lithium batteries popular in compact laser rangefinders and photographic equipment?
Q: How long is the storage life of CR123A and CR2 lithium batteries in unopened packaging?
A: CR123A (17.0 x 34.5 mm, ~1500 mAh) and CR2 (15.6 x 27.0 mm, ~800 mAh) use lithium-manganese dioxide (Li-MnO2) electrochemistry with a 3.0V voltage. These cylindrical elements provide high energy density and slow discharge across a wide temperature range from -30°C to +60°C.
Q: Why are CR123A lithium batteries specifically used in wireless security and motion sensors (such as Ajax or Eldes)?
A: Security sensors consume microamperes in standby mode, but require current peaks of up to 100 mA during an alarm or data transmission. The VIDEX CR123A battery provides low internal resistance and 1500 mAh capacity, guaranteeing 3 to 5 years of continuous security system operation.
Q: What is the difference between a single-use CR123A (3.0V) battery and a rechargeable RCR123A / 16340 (3.7V) accumulator?
A: CR123A is a single-use 3.0V lithium battery, whereas RCR123A / 16340 is a rechargeable Li-Ion accumulator with an operating voltage of 3.6V–3.7V (up to 4.2V fully charged). Inserting a 4.2V accumulator into a device intended strictly for a 3.0V battery carries a risk of burning out the sensor or flashlight microchip.
Q: Why are CR2 lithium batteries popular in compact laser rangefinders and photographic equipment?
A: CR2 offers a shortened casing (27.0 mm in length) and low weight (around 11 grams), providing an 800 mAh power reserve. This allows optical measuring device manufacturers to reduce equipment weight while maintaining a 3.0V voltage to drive camera flashes and laser diodes.
Q: How long is the storage life of CR123A and CR2 lithium batteries in unopened packaging?
A: The dry Li-MnO2 electrochemical system provides a 5-year shelf life with minimal self-discharge under 2% per year. This makes these batteries a reliable choice for backup power kits in building security systems and fire detectors.
