The world of batteries can be overwhelming, with various sizes, types, and applications. Two commonly used battery types are CR2016 and CR2032. While they may look similar, there are key differences between them. In this article, we will delve into the details of each battery type, their uses, and the main differences between them.
Understanding Battery Terminology
Before we dive into the specifics of CR2016 and CR2032 batteries, let's quickly cover some essential battery terminology:
- CR: This prefix stands for "lithium" and indicates that the battery is a lithium-based coin cell.
- 20: This number refers to the diameter of the battery in millimeters.
- 16 or 32: These numbers represent the height of the battery in millimeters.
CR2016 Battery
The CR2016 battery is a small, round battery with a diameter of 20mm and a height of 1.6mm. It is commonly used in small devices such as:
- Calculators
- Watches
- Hearing aids
- Fitness trackers
- Small toys
The CR2016 battery has a nominal voltage of 3V and a capacity of around 75-90mAh. It is designed to provide a low-drain, long-life power source for devices that require a small amount of power.
CR2032 Battery
The CR2032 battery is also a small, round battery with a diameter of 20mm and a height of 3.2mm. It is commonly used in devices such as:
- Remote controls
- Keyless entry systems
- Garage door openers
- Computer motherboards
- Medical devices
The CR2032 battery has a nominal voltage of 3V and a capacity of around 210-240mAh. It is designed to provide a moderate-drain power source for devices that require a bit more power than the CR2016.
Key Differences
Now that we have covered the basics of each battery type, let's summarize the main differences:
- Height: The most noticeable difference is the height of the batteries. The CR2016 is 1.6mm tall, while the CR2032 is 3.2mm tall.
- Capacity: The CR2032 has a significantly higher capacity than the CR2016, with around 210-240mAh compared to 75-90mAh.
- Usage: The CR2016 is typically used in low-drain devices, while the CR2032 is used in moderate-drain devices.
- Voltage: Both batteries have a nominal voltage of 3V.
Choosing the Right Battery
When choosing between a CR2016 and a CR2032 battery, consider the following factors:
- Device requirements: Check the device manual or manufacturer's website to determine the recommended battery type and size.
- Power requirements: If the device requires a low-drain power source, the CR2016 may be sufficient. If the device requires a moderate-drain power source, the CR2032 may be a better choice.
- Space constraints: If space is limited, the CR2016 may be a better choice due to its smaller size.
Conclusion
In conclusion, while the CR2016 and CR2032 batteries may look similar, they have distinct differences in terms of height, capacity, and usage. By understanding these differences, you can make an informed decision when choosing the right battery for your device.
