What Is CR Lithium Manganese Button Battery?

What is CR lithium manganese button battery?

CR battery is the universal code for lithium manganese dioxide button batteries, where "C" represents the lithium chemical system and "R" represents the circular (button) shape. It uses metallic lithium as the negative electrode and manganese dioxide as the positive electrode, with a rated voltage of up to 3.0V, which is twice that of traditional alkaline or silver oxide batteries (1.5V). This means that it can provide stronger power at the same volume.

Why choose CR lithium manganese button batteries? Five core advantages, defining industry benchmarks

1. Ultra high energy density, long-lasting battery life

The lithium manganese system endows CR batteries with extremely high energy density. This means that within the same compact size, it can store more electricity, providing devices with far longer battery life than similar products. Whether it's a computer motherboard CMOS that needs to run year-round or a smart door lock that you only replace every few years, CR batteries are the "king of endurance" that ensures its stable operation.

2. Stable working voltage, reliable performance

Throughout the entire discharge cycle, CR batteries can maintain an extremely stable voltage output curve. The device will not experience functional abnormalities due to a gradual decrease in voltage (such as darkening of the display screen or weakening of the signal), and will always receive stable and pure energy, ensuring precise timing, error free data transmission, and reliable control.

3. Excellent temperature adaptability, fearless of extreme cold and heat

CR batteries can maintain excellent performance from low temperatures of -20 ℃ to high temperatures of+60 ℃. This feature makes it an ideal choice for devices such as car remote keys, outdoor thermometers, and security sensors that require stable operation in harsh environments, truly achieving "all climate" reliability.

4. Ultra light weight and excellent leak resistance

The battery adopts a fully sealed structure design and mercury free environmentally friendly materials, effectively preventing the risk of damaging the internal circuits of expensive equipment due to battery leakage. At the same time, its lightweight design is very suitable for portable electronic products that are sensitive to weight, such as Bluetooth earphones, calculators, etc.

5. Long storage life and extremely low self discharge rate

The annual self discharge rate of CR batteries is less than 1%, and they have an ultra long shelf life of over 10 years. You don't have to worry about the battery running out on the shelf or during the backup period. You can buy with peace of mind and use with peace of mind.
