Informative Explanation of Features and Specifications of Both Products
CR2032 Battery
The CR2032 battery stands out with its compact 20 mm diameter and 3.2 mm thickness, making it a perfect fit for small devices that require a stable power source. Operating at a standard voltage of 3V, this battery offers a capacity ranging from 210 to 240 mAh, which translates into a long-lasting power supply for basic electronics. One of its standout features is its wide availability and cost-effectiveness, making it a popular choice for everyday gadgets.
The battery is designed to perform reliably within a temperature range of -20°C to 70°C, suitable for most indoor and some outdoor applications. It has a self-discharge rate of approximately 1% per year, ensuring that it retains its charge well when stored. However, it may not be the best choice for devices exposed to extreme temperatures.
BR2325 Battery
In contrast, the BR2325 battery is known for its robust performance in harsh environments. With a slightly larger diameter of 23 mm and a thinner profile of 2.5 mm, it is ideal for specialized devices that require a stable power source in extreme conditions. Like the CR2032, it operates at a 3V voltage but offers a slightly lower capacity between 165 and 200 mAh.
A defining feature of the BR2325 is its exceptional temperature tolerance, ranging from -30°C to 85°C, making it a superior choice for devices used outdoors or in industrial settings. Additionally, it has a lower self-discharge rate of about 0.5% per year, ensuring efficient energy retention over longer periods.
Differences Between Products
While both batteries share similarities in voltage and general usage, their differences lie primarily in size, capacity, and environmental performance. The CR2032 is smaller in diameter but thicker compared to the BR2325. It offers a higher capacity, making it suitable for devices that require more energy over time. However, its temperature tolerance is lower, which may limit its usage in extreme conditions.
Conversely, the BR2325 is tailored for environments with temperature fluctuations, boasting a broader operating range. Its slightly lower capacity may be a trade-off for better performance in adverse conditions. The lower self-discharge rate of the BR2325 means it can store energy more efficiently, making it an excellent choice for devices that are not used frequently but must remain operational when needed.
