Why Source Omnergy CR2032T for Your Project?

■ Superior Thermal Endurance (-40°C to +85°C)

While consumer-grade CR2032 batteries are limited to 70°C, the CR2032T features a specialized heat-resistant electrolyte. This ensures the battery will not swell, leak, or lose capacity in high-heat environments like car dashboards, industrial sensors, or outdoor smart meters.

■ Precision 220mAh Capacity Management

Our CR2032T is optimized for long-term pulse discharge. With a stable 3V output and a 10-year shelf life, it provides the reliable “set-and-forget” power needed for RTC (Real-Time Clock) backup and low-power wide-area network (LPWAN) devices.

■ Leak-Proof & Vibration Resistant

Designed for the rigors of the automotive industry, the CR2032T utilizes a reinforced stainless steel shell and an advanced sealing ring. It is tested to withstand high-vibration environments, making it the preferred choice for TPMS (Tire Pressure Monitoring Systems).
