CR2032 vs CR2025: Which Coin Cell Battery Is Best for Your Device? Key Differences, Features, and Buying Guide

Button cell batteries are essential components in many electronic devices. As non-rechargeable lithium batteries, they are commonly used in small devices such as car key fobs, digital watches, and hearing aids. Among them, the CR2025 and CR2032 are two of the most widely used button cell batteries. While they share similar characteristics, they differ in key aspects such as size, capacity, and lifespan. This article will explain the differences between CR2025 and CR2032 to help you choose the right battery for your needs.

Button lithium batteries are typically labeled with "CR" followed by a series of numbers. The "C" stands for lithium manganese dioxide chemistry, while the "R" indicates the battery is round in shape. The first two digits represent the battery’s diameter in millimeters, and the last two digits indicate its height.

For example: A CR2025 battery is a lithium-manganese (LiMnO2) coin cell with a diameter of 20mm and a height of 2.5mm.

The Similarities Between CR2032 and CR2025 Batteries?

The CR2025 and CR2032 are 3V lithium coin batteries with the same 20mm diameter, voltage, and chemistry. Both power small devices like calculators, watches, medical tools, and smart keys. When stored under similar conditions, they offer the same shelf life if from the same brand.

1. Features

· Type: Both are Non-rechargeable lithium battery

· Voltage: Both have a nominal voltage of 3V.

· Chemical Composition: Both use lithium manganese dioxide (LiMnO2).

· Diameter: Both have a diameter of 20mm.

· Operating Temperature Range: Both exhibit a comparable temperature operating range from -30 to 60 degrees Celsius.

· Shelf Life: Their shelf life remains consistent under identical storage conditions.

Applications: Both can be used in similar devices, such as calculators, watches, computer motherboards, and some medical devices.

2. Benefits

· Environmental friendly, Lightweight

· High density of energy

· Low self-discharge (less than 1% of its power each year)

· Low internal resistance

· No memory effect

· Free of mercury

· Safety assurance: No fire, No explosion, No leakage

Most major battery brands like Duracell, EVE Energy, Energizer, Panasonic, Philips, Maxell, Murata (formerly Sony), Renata, and others carry both the CR2025 and CR2032 batteries in their product catalogs as they are two of the most widely used batteries worldwide.

The difference between CR2025 and CR2032  Batteries?

1. Size and Thickness:

The most noticeable difference between the two battery types is their thickness. The CR2032 is 3.2mm thick, while the CR2025 is 2.5mm thick.

2. Capacity:

Due to its extra 0.7mm thickness, the CR2032 has a higher capacity. A standard CR2032 typically has a nominal capacity of 225mAh, whereas a CR2025 usually offers around 160mAh.

3. Discharge Current:

The CR2032 can handle a maximum continuous discharge current of up to 20mA, while the CR2025 generally supports only around 10mA. Therefore, it’s important to match the battery type with your device's actual current requirements.

4. Usage Time:

Because the CR2025 has a smaller capacity and thinner design, it generally provides shorter usage time and may need to be replaced more frequently than the CR2032.

CR2032 vs. CR2025: Which One Should You Choose?

Batteries are not universal or one-size-fits-all. Even though the CR2032 and CR2025 are quite similar, we recommend choosing based on your specific needs.

1. Device Requirements: Look at your device's manual to find the right type of battery. This is important for it to work well.

2. Size Constraints: Consider the size of the battery compartment. If your device has limited space, the CR2025 battery is the better choice. The CR2032 is better for devices with more room.

3. Power Consumption: Check how much power your device needs. If it is used a lot, use CR2032 batteries. The CR2025 is suitable for devices that don't need long-lasting power.

4. Power Needs: The CR2032 battery is preferable for devices requiring consistent or higher power, such as fitness trackers or advanced remotes. The CR2025 lithium battery is better for low-energy devices like basic watches or calculators.

5. Cost and Availability: The CR2025 is typically cheaper, making it a more cost-effective option for low-power devices. However, the CR2032 coin cell battery is often more widely available and suitable for devices with higher energy demands.

Selection Tips:

· Use CR2025 battery for Slim devices with low power needs, such as small toys, key fobs, and calculators.

· Use CR2032 battery for Devices that require more power and longer battery life, such as fitness trackers, car key fobs with extra functions, or medical devices.

By considering these factors, you can ensure that you choose the right battery for your specific needs, preventing unnecessary battery replacements and ensuring optimal device performance. Always check the device's manual or battery compartment to ensure compatibility before choosing.

FAQ

Can you use CR2032 instead of CR2025?

Not ideally. CR2032 is thicker and may not fit in place of a CR2025. Using a CR2025 instead of a CR2032 can cause poor contact or shorter run time. Temporary fixes (like foil) may help in emergencies, but always use the correct battery type when possible.

Are there any safety tips when using CR2032 and CR2025 batteries?

Yes. Store in a dry place, avoid heat and metal contact, don’t recharge, and keep away from kids. Recycle used batteries properly.
