Informative Explanation of Features and Specifications of Both Products
CR2025 Battery
The CR2025 battery is a lithium coin cell known for its larger diameter of 20 mm and thickness of 2.5 mm. With a voltage of 3 volts, it is capable of delivering a significant capacity of 170 milliampere-hours (mAh). This makes it ideal for devices that require more power, such as remote controls, calculators, and some digital watches. Its larger size also means it can sustain longer usage periods compared to smaller batteries.
CR1620 Battery
The CR1620 battery, in contrast, is smaller with a diameter of 16 mm and a thickness of 2.0 mm. Despite sharing the same 3-volt output, its capacity is limited to 70 mAh, reflecting its suitability for smaller devices with lower power demands. Common applications include key fobs, small medical devices, and other compact electronics. Its lightweight nature, at just 1.2 grams, is advantageous for devices where weight is a critical factor.
Differences Between Products
The primary differences between the CR2025 and CR1620 batteries lie in their physical dimensions, capacity, and corresponding use cases. The CR2025s larger size and higher capacity make it more suitable for devices that require prolonged power delivery. Its applications are diverse, extending from remote controls to larger digital gadgets. On the other hand, the CR1620s compact form factor is specifically advantageous for devices where space is a premium. Its lower capacity aligns with gadgets that have minimal power consumption, ensuring that the battery size does not compromise the devices design or functionality.
Additionally, the weight difference between the two batteries, with the CR2025 being more than double the weight of the CR1620, also affects their usability in certain devices. For portable and lightweight electronics, the CR1620 offers a clear advantage, while the CR2025 is better suited for applications where battery longevity is prioritized over compactness.
