-
2016: This battery has a diameter of 20mm and a height of 1.6mm, making it thinner than the CR2025.
The difference in height is significant, impacting the overall size and fit of the battery within devices. While CR2025 batteries may not fit in devices designed for 2016 batteries, the reverse is not true.
2. Voltage and Capacity:
Both CR2025 and 2016 batteries have a nominal voltage of 3V. However, their capacity, measured in milliamp-hours (mAh), differs significantly:
-
CR2025: Typical capacity ranges from 150mAh to 220mAh, depending on the manufacturer and quality.
-
2016: The typical capacity of a 2016 battery is around 90mAh to 130mAh.
The higher capacity of the CR2025 allows it to provide power for longer durations compared to the 2016 battery.
3. Applications and Use Cases:
The choice between CR2025 and 2016 batteries depends heavily on the specific application and its power requirements.
CR2025 Applications:

Calculators: Some calculators, especially those with advanced features, are powered by CR2025 batteries.
-
Electronic Toys: Some toys, especially those with electronic components, might use CR2025 batteries.
2016 Applications:
-
Coin-Operated Devices: Vending machines, arcade games, and other coin-operated devices often use 2016 batteries for their internal circuitry.
-
Remote Controls: Some remote controls, especially those for TV sets, use 2016 batteries due to their compact size.
-
Calculators: Basic calculators and some scientific calculators are powered by 2016 batteries.
-
Electronic Gadgets: Small electronic gadgets like fitness trackers, Bluetooth speakers, and certain USB devices may use 2016 batteries.
4. Battery Life and Performance:
The battery life of both CR2025 and 2016 batteries is influenced by factors like device usage, temperature, and battery quality. However, due to their different capacities, the expected battery life varies:
-
CR2025: Typically offers a longer battery life compared to 2016, ranging from several months to a few years, depending on the application.
-
2016: Offers a shorter battery life, usually ranging from several months to a year, depending on the device’s power consumption.
5. Availability and Cost:
Both CR2025 and 2016 batteries are widely available at electronics stores, supermarkets, and online retailers. Their prices are generally comparable, with CR2025 batteries slightly more expensive due to their larger capacity.
6. Safety Considerations:
Lithium-ion batteries, including CR2025 and 2016, can pose safety risks if mishandled. It’s important to follow safety guidelines:
-
Avoid short circuits: Never connect the positive and negative terminals of a battery directly.
-
Do not overheat: Extreme temperatures can damage the battery and lead to leakage or explosion.
-
Proper disposal: Dispose of used batteries responsibly, following local regulations.
-
Keep away from children: Children should be supervised when handling batteries to prevent accidental ingestion.
Choosing the Right Battery: A Decision Guide
When deciding between CR2025 and 2016 batteries, consider the following factors:
-
Device Requirements: Check the device’s specifications to determine the recommended battery type and its size.
-
Power Consumption: If your device has high power consumption, opt for the higher capacity CR2025 battery.
-
Battery Life: If you need a battery with a longer lifespan, choose the CR2025.
-
Space Constraints: If your device has limited space, the thinner 2016 battery might be a better choice.
-
Availability and Cost: Compare prices and availability of both battery types before making a purchase.
Alternatives to CR2025 and 2016 Batteries
While CR2025 and 2016 batteries are popular choices, other battery types can be considered:
-
CR2032: This battery has the same diameter as CR2025 and 2016 but is taller, offering a higher capacity.
-
CR1632: This battery is smaller than CR2025 and 2016, with a diameter of 16mm and a height of 3.2mm, providing a lower capacity.
-
Rechargeable Batteries: For devices with low power consumption, rechargeable batteries like button cell lithium-ion batteries or nickel-metal hydride (NiMH) batteries can be a sustainable alternative.
Conclusion: The Best Choice for Your Needs
Choosing between CR2025 and 2016 batteries ultimately depends on the specific application and its requirements. CR2025 offers higher capacity and longer battery life, making it suitable for devices with higher power demands. 2016, with its smaller size and lower capacity, is ideal for devices with limited space and lower power consumption.
By carefully considering the factors outlined above, you can choose the best battery type for your electronic needs, ensuring optimal performance and longevity. Remember to always prioritize safety and dispose of batteries responsibly.
