CR2025 Battery vs. CR2032 Battery: A Comprehensive Comparison

CR2025 vs. CR2032 Batteries: What is the Difference? - ElectronicsHacks

Introduction

Button batteries, also known as coin cells, are small, flat, and round batteries commonly used in electronic devices such as watches, calculators, key fobs, and medical devices. Among the various types of button batteries available, CR2025 and CR2032 batteries are two popular choices. While they share similarities, there are also key differences between these two battery models. This article provides a comprehensive comparison of CR2025 vs. CR2032 batteries, covering their specifications, applications, advantages, and disadvantages.

Specifications

1. Size:

CR2025: Diameter: 20mm, Height: 2.5mm
CR2032: Diameter: 20mm, Height: 3.2mm

2. Voltage:

Both CR2025 and CR2032 batteries have a nominal voltage of 3 volts.

3. Capacity:

CR2025: Typically 150-160mAh
CR2032: Typically 220-240mAh

4. Chemistry:

Both CR2025 and CR2032 batteries use lithium manganese dioxide (LiMnO2) chemistry.

Applications

CR2025 and CR2032 batteries are used in a wide range of electronic devices, including:

CR2025:

  • Watches
  • Calculators
  • Key fobs
  • Small medical devices
  • Toys
  • Remote controls

CR2032:

  • Watches
  • Calculators
  • Key fobs
  • Larger medical devices
  • Electronic scales
  • Bluetooth devices
  • Memory backup systems

Advantages

CR2025:

  • Smaller and lighter than CR2032 batteries, making them suitable for compact devices.
  • Lower capacity, which may be advantageous for applications with low power consumption.
  • Widely available and affordable.

CR2032:

  • Higher capacity than CR2025 batteries, providing longer battery life for devices with higher power consumption.
  • Suitable for applications where space is not a constraint.
  • Also widely available and affordable.

Disadvantages

CR2025:

  • Lower capacity may not be sufficient for devices with high power consumption.
  • May require more frequent replacement than CR2032 batteries in high-drain applications.

CR2032:

  • Larger and heavier than CR2025 batteries, making them less suitable for compact devices.
  • Higher capacity may lead to shorter shelf life compared to CR2025 batteries.

Interchangeability

CR2025 and CR2032 batteries are not interchangeable due to their different heights. While they have the same diameter, the extra height of the CR2032 battery may prevent it from fitting properly into devices designed for CR2025 batteries.

Conclusion

CR2025 and CR2032 batteries are both versatile and widely used button batteries with distinct characteristics. CR2025 batteries are smaller and have lower capacity, making them suitable for compact devices with low power consumption. CR2032 batteries, on the other hand, have higher capacity and are ideal for applications where longer battery life is required. When choosing between these two battery models, it is important to consider the specific requirements of the device and the desired battery life. By understanding the differences between CR2025 vs. CR2032 batteries, users can make informed decisions and select the optimal battery for their needs.
