Product Description

Product Description

CR1632

The CR1632 is a reliable lithium metal button cell based on the Li/MnO₂ chemical system, engineered to deliver stable power in compact and demanding electronic devices. With a nominal voltage of 3.0V and a nominal capacity of 140mAh, it offers extended service life and consistent energy output, making it ideal for applications where space is limited but performance cannot be compromised.

Designed to operate across a wide temperature range from -30°C to +85°C, this battery performs reliably in both extreme cold and heat, suiting it for outdoor, industrial, and automotive environments. It supports a standard continuous discharge current of 0.1mA with the ability to handle up to 5mA continuously and 15mA in pulse mode, providing versatility for low-power devices such as memory backup, calculators, medical sensors, key fobs, and precision instruments.

Weighing only 1.8g, the CR1632 is lightweight yet durable, meeting strict quality standards for long-term storage under recommended conditions of 20±5°C and 55±20% relative humidity. Whether used in consumer electronics, IoT devices, or specialized industrial tools, this button cell combines energy density, environmental adaptability, and dependable power in a miniature form factor.
