Why Choose CR3032T for Your Project?
Superior Thermal Stability: Unlike standard CR3032 cells, the "T" series (T-Type) is specifically optimized to operate in extreme heat and cold, ensuring reliability in automotive under-the-hood or outdoor industrial environments.
Highest Capacity in Class: With 500mAh, it offers significantly longer runtimes compared to standard 20mm series batteries, reducing maintenance costs and battery replacement frequency.
Excellent Leakage Resistance: Our CR3032T utilizes a specialized sealing structure and heat-resistant electrolyte to prevent leakage even under prolonged high-temperature exposure.
Long Shelf Life: Features a low self-discharge rate, maintaining over 90% capacity even after 5-10 years of storage.
Common Applications
Automotive Systems: Tire Pressure Monitoring Systems (TPMS), Electronic Toll Collection (ETC) tags.
Industrial IoT: High-temperature sensors, smart meters, and tracking devices.
Medical Devices: Sterilizable equipment and portable medical monitors.
Memory Backup: CMOS power backup for servers and industrial PCs.
Technical FAQ
Q1: What is the difference between CR3032 and CR3032T?
A: While both share the same dimensions (30mm x 3.2mm) and 500mAh capacity, the CR3032T is specifically formulated for high-temperature resistance. Standard CR3032 batteries typically operate up to 70°C, whereas the CR3032T supports up to 40°C or 85°C (depending on specific grade).
Q2: Can we customize the battery terminals?
A: Yes. As a professional B2B supplier, we provide various terminal types (SMT tabs, PC pins, or wire leads) to meet your PCB mounting requirements.
