What is a CR Battery?

The CR battery is a cylindrical lithium manganese dioxide (Li-MnO2) battery that cannot be charged. It works at a voltage of 3V. Many people select it for its high energy and steady performance. This makes it an excellent choice for those who want reliable and lasting batteries. The name shows its size: 26mm wide and 50mm long. Even though it is small, it offers a steady output over time. This battery is built for stability. It has low self-discharge, dropping by less than 1% yearly at 25°C. Also, it can function in very hot or very cold temperatures, from -40°C to 85°C. Because of this, the CR battery is perfect for essential uses like gas meters, security systems, and medical equipment.

4. Stable Working Voltage and Current: The CR lithium battery provides steady voltage and current during its life. This reliability is critical for devices that need consistent power.
5. Low Self-Discharge Rate: The CR 3V lithium battery self-discharges less than 1% each year at room temperature (25ºC). This means it can be stored for a long time and remain almost fully charged when needed.
6. Long Storage Life: With its low self-discharge and strong design, the CR 3V battery can last up to 10 years when stored. This makes it a smart choice for emergency devices or tools that rarely get used.
7. Many Available Terminations: The CR battery supports several types of connections, like axial leads and polarized tabs. This makes it easy to use on many different devices.

Typical Applications of CR Lithium Battery

Let's look at how the CR 3V battery is used daily. We will also discuss why it is an excellent choice for these situations:

1. Utility Meters

Utility meters, like those for gas, electricity, and water, often use CR batteries. They need these batteries to work for many years without requiring any care. These meters are usually installed in hard-to-reach spots. A battery that lasts a long time without needing a change is really helpful. This battery provides steady power for several years, making it a great option.

2. Security Alarm Systems

Home and business security systems require steady power to function correctly. A power failure can leave you without protection. The CR lithium battery is commonly used in motion detectors, wireless alarms, and door sensors. People prefer it for its stable voltage and long lifespan. This lithium battery helps ensure the security system keeps working, even when the power goes out.

3. GPS Tracking Devices

Tracking devices need strong batteries to send signals for a long time, especially when they are far away. The CR battery is popular for its strong energy and dependability. This helps GPS devices stay on for longer. They can give precise information without needing a recharge or a battery change.

4. Memory Backup

Some electronic devices and industrial tools use memory backup systems to keep vital data safe when the main power shuts off. The CR 3V lithium battery is excellent for this. It gives long-lasting power and steady voltage. This ensures that memory systems can keep data secure and correct. It is ideal for backup in CMOS memory, RTC (real-time clock), and computers.

5. Medical Devices

Some portable or implantable medical devices use CR batteries for power. These devices are crucial for health functions. So, having a safe and reliable battery is essential. This battery provides a steady output. That way, the device can work well without issues.

How to Choose the Right CR Battery?

Picking the right CR 3V lithium battery is essential if you want your device to work well and last longer. Here are a few easy things to keep in mind:

Power Requirements | Working Environment | Size Compatibility | Trusted Brand | Budget & Quantity
