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).
■ B2B Factory Customization
Omnergy isn’t just a supplier; we are your manufacturing partner. We offer:
• Custom Solder Tabs/Pins: Horizontal, vertical, configurations.
• Wire & Connector Assembly: custom harnesses.
• Bulk Packaging: Industrial tray .
Primary Application Scenarios
• Automotive Electronics: TPMS sensors, keyless entry (PKE), and E-call systems.
• Industrial Computing: CMOS/BIOS backup for industrial motherboards and servers.
• Smart Energy: Smart gas/water meters and grid monitoring devices.
• IoT Infrastructure: Outdoor gateways, tracking tags, and agricultural sensors.
FAQ Section
Q: What is the main difference between CR2032 and CR2032T?
A: The “T” stands for Temperature. While both have a 20mm diameter and 3.2mm thickness, the CR2032T is an industrial version designed to operate up to 85°C. Standard CR2032 batteries are designed for room temperature and may fail or leak if exposed to extreme heat.
Q: Can Omnergy CR2032T replace Panasonic or Maxell CR2032T?
A: Yes. Omnergy CR2032T is a high-quality, fully compatible equivalent. It meets or exceeds the discharge performance and safety standards (UL, RoHS) required for high-end industrial and automotive applications.
Q: Does the CR2032T support pulse discharge for IoT devices?
A: Absolutely. The internal resistance of the CR2032T is optimized to handle the periodic high-current pulses required by Bluetooth Low Energy (BLE), LoRa, and NB-IoT transmission
