Characteristics of CR Batteries

Here are the key characteristics of CR batteries written in English:

Characteristics of CR Batteries

1. Lithium Manganese Dioxide Chemistry (Li-MnO₂)
   CR batteries use lithium as the anode and manganese dioxide as the cathode. This chemistry provides high energy density and long storage life.

2. High Voltage Output
   A single CR battery typically provides 3.0 volts, which is higher than the 1.5 V offered by alkaline or silver-oxide button cells. This makes CR batteries suitable for devices requiring stronger, stable power.

3. Long Shelf Life
   Thanks to low self-discharge, CR batteries can maintain most of their capacity for 5–10 years (sometimes up to 12 years), making them ideal for infrequently used devices.

4. Wide Operating Temperature Range
   CR batteries function reliably from around –20°C to +60°C. Some models perform even beyond this range, supporting outdoor or industrial applications.

5. Stable Discharge Curve
   They provide a steady and consistent voltage output throughout most of their lifespan, ensuring reliable device performance until the battery is nearly depleted.

6. High Energy Density
   CR batteries store a large amount of energy relative to their size and weight, making them suitable for compact devices with long battery-life requirements.

7. Good Safety Performance
   The chemistry is thermally stable and has built-in safety mechanisms, reducing the risk of leakage or swelling under normal usage.

8. Common Applications
   CR batteries are widely used in:

• Remote controls

• Car key fobs

• Medical devices

• Sensors

• Cameras

• Watches and small electronics
