Purpose: CR2025 batteries are used to provide long-lasting power for devices that require low to moderate power consumption. These batteries are known for their reliability, relatively long shelf life, and ability to deliver consistent power over time.
Characteristics:
- Voltage: CR2025 batteries typically provide around 3 volts of power, making them suitable for various low-power applications.
- Capacity: They have a nominal capacity of approximately 160-165 milliampere-hours (mAh), which can vary slightly based on the manufacturer.
- Chemistry: These batteries are composed of lithium metal, which provides a relatively high energy density.
- Size: The "2025" in the battery's name refers to its dimensions, 20mm in diameter and 2.5mm in height.
- Low Self-Discharge: They have a low self-discharge rate, allowing them to hold their charge for extended periods when not in use.
Heat Dissipation: While in use, CR2025 batteries generally do not produce a significant amount of heat. However, as with any battery, if subjected to unusually high current demand or short-circuit conditions, they can heat up. Since these batteries are not designed for high current drain applications, it's important to ensure that the devices they power are designed within their specified current limitations to minimize the risk of excessive heat generation. Additionally, it's crucial to operate these batteries within their specified temperature ranges to ensure optimal performance and safety.
When selecting or designing a device using the CR2025 battery, it's essential to consider factors such as proper thermal insulation and heat dissipation to prevent potential overheating, especially if the device incorporates components that are sensitive to heat.
