The CR1632 3V lithium coin cell battery is engineered for applications where compact size, lightweight construction, and reliable power are essential. Using lithium manganese dioxide (Li-MnO₂) chemistry, it delivers a nominal voltage of 3.0V with excellent discharge stability, ensuring consistent device performance over its lifespan. With a typical capacity of 130mAh and an exceptionally low self-discharge rate of ≤1% per year, this battery maintains energy for extended storage periods, making it ideal for standby or backup applications.

Its wide operating temperature range of -30°C to +85°C ensures dependable performance in both indoor and outdoor conditions, while the flat discharge curve provides steady voltage until near depletion. Commonly used in automotive keyless entry systems, medical monitoring devices, fitness trackers, watches, calculators, and RTC (real-time clock) backup functions, the CR1632 is built to meet the needs of modern portable electronics.

Designed as a non-rechargeable primary cell, it requires no protection circuit and offers high charge/discharge efficiency. The compact dimensions (16mm diameter × 3.2mm height) allow it to fit seamlessly into slim device profiles, while its lightweight nature (approx. 1.9g) makes it a preferred choice in portable electronics where every gram matters.
