Why Specify Our CR3032? Engineered for Slim-Line Endurance
1. Broad Footprint, Massive Capacity (500mAh)
Space constraints are the enemy of battery life. By utilizing a wider 30mm diameter, this cell achieves a robust 500mAh capacity without increasing device thickness. It offers the perfect golden ratio of ultra-thin design and extended operational life, dramatically reducing maintenance intervals.
2. Unwavering Thermal Stability (-20°C to 70°C)
Industrial and commercial devices do not live in perfectly climate-controlled environments. Formulated with advanced lithium chemistry, our CR3032 guarantees stable, continuous voltage discharge through freezing warehouses and sweltering automated factory floors, reliably operating from -20°C to 70°C.
3. The "Store & Forget" Advantage (<2% Annual Self-Discharge)
Inventory aging should not mean capacity loss. Thanks to high-purity internal components and a precision-engineered outer seal, the CR3032 boasts an ultra-low self-discharge rate of less than 2% per year. You can stock up your supply chain knowing these batteries will perform like new years after purchase.
4. Exacting Dimensional Precision (Φ30.0 × 3.2mm)
Manufactured to flawless global tolerances, this wide-format cell ensures perfect contact in standard CR3032 PCB surface-mounts and battery holders. Its expansive surface area also provides excellent electrical contact, preventing micro-disconnects in high-vibration industrial settings.
Core Application Ecosystems
The unique geometry of the CR3032 makes it the battery of choice for applications requiring a combination of thinness and high capacity. It excels in:
Point of Sale (POS) Terminals: Providing essential memory backup and cryptographic key retention in modern, ultra-slim retail payment devices.
Industrial Control Boards: Acting as a highly reliable, low-profile Real-Time Clock (RTC) and SRAM backup for PLCs, automated machinery, and control systems.
Smart Cards & Active Badges: Powering RFID cards, active corporate security badges, and specialized toll-pass transponders where thickness is strictly limited.
Medical & Wearable Electronics: Supplying steady power to slim, body-worn monitoring patches and portable diagnostic equipment.
Specialty Measurement Instruments: Delivering long-term standby power for digital calipers, micrometers, and precision testing gear.
Expert FAQ: Sourcing the CR3032
Q: What is the distinct advantage of a CR3032 over a standard CR2032? A: The primary difference is the physical diameter and resulting power capacity. A CR2032 is 20mm wide and typically holds around 220mAh. The CR3032 is significantly wider at 30mm, allowing it to pack a 500mAh capacity while remaining just as thin (3.2mm). It offers more than double the runtime for devices that can accommodate a wider battery slot.
Q: Is the CR3032 suitable for devices that experience frequent vibrations? A: Yes. Its broad 30mm surface area allows for wider, more secure contact points in battery holders, making it highly resistant to power interruptions caused by mechanical vibration in industrial environments.
Q: Can I get these batteries with custom solder tabs for PCB mounting? A: Absolutely. Because the CR3032 is frequently used in industrial motherboards, we offer custom spot-welding services, including standard horizontal, vertical, and custom-angled pins/tabs for seamless PCB integration.
