A CR2025 battery can last 3-4 years in a car key fob because it’s used only occasionally. However, in a device that’s used more frequently, it usually lasts about a year to power the device needs. Proper storage in cool, dry conditions can extend its shelf life up to 10 years.
After reading this article, we want to give our customers helpful information about the similarities and differences between CR2025 batteries. This will help them understand and use these commonly confused batteries correctly.
What is a CR2025 battery?
The CR2025 battery is a small, flat lithium coin cell that is 20mm wide and 2.5mm thick. It provides 3 volts of power and has a capacity of up to 170mAh. This battery is commonly used in devices with limited space, such as smaller watches and key fobs.
While it offers a shorter life compared to the CR2032, it is suitable for similar applications where space is a concern. The CR2025 battery is also known by various other names, including BR2025 and DL2025.
What is the current of a CR2025 battery?
The CR2025 battery provides a voltage of 3 volts. The current it supplies depends on the device it powers and its power needs.
Generally, the CR2025 battery delivers a small, steady current suitable for low-power devices like watches and key fobs. It is designed to offer reliable performance over a long period with consistent current output.

What Uses a CR2025 Battery?
Similar to the CR2025 battery, powers many devices including computer motherboards, car key fobs, watches, calculators, and toys.
It’s also used in door chimes, LED lights, pedometers, and medical devices. The CR2025 is especially good for devices with tight battery compartments due to its thinner size.
What is the highest capacity of the CR2025 battery?
The highest capacity of a battery is about 170mAh. This means it can store up to 170 milliampere-hours of energy. This capacity is enough for many small devices, providing reliable power over a long period, but it’s less than the CR2032 battery, which has a higher capacity.

Buying CR2025 Lithium Coin Cell Batteries Online:
When buying CR2025 lithium coin cell batteries online, look for reputable sellers and check customer reviews. Ensure you are buying genuine, high-quality batteries by choosing trusted brands.
Compare prices and check the expiry dates to get fresh batteries. Carefully check product details to make sure the battery’s size and specifications are correct before buying.
What are the Differences Between CR2032 and CR2025 Batteries?
Dimensions/Battery Size:
The CR2032 battery is 20mm wide and 3.2mm thick. The CR2025 is the same width, 20mm, but thinner at 2.5mm. This makes the CR2025 more suitable for devices with less space, though it has a slightly lower capacity than the CR2032.
Capacity:
The CR2032 battery has a higher capacity of 235mAh, compared to the CR2025’s 170mAh. This means the CR2032 lasts longer and is better for high-demand applications. If battery life is less critical, you can use the CR2025 as a suitable alternative to the CR2032.
Weight:
The CR2032 weighs 3 grams, while the CR2025 weighs 2.6 grams. If weight is not a major concern, you can use a CR2025 in place of a CR2032. However, if a lighter device is preferred, the CR2025 is a better choice as it is slightly lighter.
Durability:
A higher mAh rating means a battery lasts longer. For example, a battery with 240mAh, like the CR2032, lasts longer than one with 170mAh, like the CR2025. Thus, the CR2032 provides more power and generally lasts longer than the CR2025.
Can I use a CR2025 battery instead of a CR2032?
Yes, you can use a CR2025 battery instead of a CR2032 in many cases. Both batteries are the same size, but the CR2025 has a lower capacity and shorter life. If your device can handle this difference, the CR2025 can be a suitable replacement.
Are CR2032 and CR2025 batteries interchangeable?
While CR2032 and CR2025 batteries are similar but not always interchangeable. They both have a 20mm diameter, but the CR2032 is thicker at 3.2mm compared to the CR2025’s 2.5mm.
The CR2032 also has a higher capacity and lasts longer. If your device fits both sizes, you can use the CR2025, but check for compatibility first.
Frequently Asked Questions:
1. What factors affect the lifespan of a CR2025 battery?
The CR2025 battery is affected by how often the device uses power, the battery’s storage conditions, and the temperature. Using the battery in high-drain devices or extreme temperatures can shorten its life.
2. Can a CR2025 battery be stored for long periods?
Yes, a CR2025 battery can be stored for long periods, up to 10 years, if kept in a cool, dry place. Proper storage helps maintain its charge and ensures it stays usable when needed.
3. What are the risks of using a low-quality CR2025 battery?
Using a low-quality CR2025 battery can lead to shorter life, leaks, or even device damage. These batteries may not provide reliable power and could cause malfunctions or safety issues. Always choose high-quality batteries for better performance and safety.
