Before diving into the details of the comparison between CR2477 and CR2032 batteries, it’s important to understand their importance and application in modern-day electronics. These small, compact batteries are used in a wide range of devices, from simple household appliances to advanced medical equipment. The reason for their popularity lies in their ability to provide reliable, long-lasting power for low-drain devices.
The CR2477 and CR2032 batteries are two of the most commonly used coin cell batteries in the market today. Both batteries have their own unique features and characteristics that make them suitable for specific applications. In this article, we will examine these batteries in detail and compare them based on their chemistry, voltage, capacity, and applications. Understanding the differences between these batteries can help you make an informed decision when choosing the right battery for your device.
Differences Between CR2477 and CR2032
Although these two batteries are quite similar, there are some significant differences. The most significant difference between these models lies in their dimensions and capacity (mAH). Let’s go through them one by one.
Chemistry
The chemistry of a battery determines how it stores and releases energy. The CR2477 battery contains a lithium-manganese dioxide (LiMnO2) chemistry, which is known for its high energy density and stability over time. This chemistry is also resistant to leakage, making it a reliable choice for long-term use. On the other hand, the CR2032 battery contains a lithium-ion (Li-ion) chemistry, which is more efficient and provides a higher energy density than LiMnO2. Li-ion batteries are also known for their ability to provide high-output currents, making them suitable for high-drain applications.
Voltage
The voltage of a battery is the measure of electrical potential between its positive and negative terminals. Both the CR2477 and CR2032 batteries have a nominal voltage of 3 volts.

Size
One of the most important differences between these two batteries is their size. It is crucial to note that they are not interchangeable for the same device. Specifically, the CR2477 (7.7mm) is more than twice as thick as the CR2032 (3.2mm). They also differ in width, although not significantly, with the CR2477 being 24mm wide and the CR2032 being 20mm wide.
Of course, such a difference in dimensions also entails a difference in weight, with the CR2477 (9,9 g) being three times heavier than the CR2032 (3.1 g).
Capacity
The capacity of a battery refers to the amount of charge it can hold and provide. The CR2477 has a higher capacity than the CR2032, with a typical capacity of 1000mAh compared to the CR2032’s capacity of 225mAh. This means that the CR2477 battery can provide more power for a longer period of time than the CR2032 battery.
Applications
The CR2477 battery is commonly used in high-drain applications that require a long lifespan and high energy capacity. Examples of devices that use the CR2477 battery:
- Medical devices
- Electronic door locks
- Wireless sensors.
The high capacity of this battery also makes it suitable for devices that require intermittent power.
On the other hand, the CR2032 battery is commonly used in low-drain devices that require a small, reliable power source. Devices such as:
- Calculators
- Remote controls
- Key fobs
- Small LED lights
Its small size and low capacity make it a cost-effective solution for such applications.
Conclusion
Overall, the CR2477 and CR2032 batteries are both reliable power sources that are widely used in various applications. The choice between the two batteries ultimately depends on the specific needs of the device being powered. It’s important to consider factors such as size, voltage, and capacity when selecting a battery for a particular application.
If the device requires a high capacity and longer lifespan, the CR2477 battery may be the better choice due to its higher capacity and stability over time. On the other hand, if the device requires a small, reliable power source, the CR2032 battery may be a more cost-effective solution.
Regardless of the choice, it’s important to remember that proper handling and disposal of batteries are critical to ensure safety and environmental responsibility. Always follow the manufacturer’s instructions for the proper use and disposal of batteries to minimize the risk of injury and environmental harm.
