CR2032D 3V 220mAh low-temperature primary lithium button cell for industrial PCB mounting

ザ・ CR2032D is a specialized, industrial-grade primary lithium coin cell engineered for mission-critical applications in extreme cold environments. While standard lithium batteries lose significant conductivity and voltage stability as temperatures drop below -20℃, the “「D」シリーズ（低温耐性） utilizes a proprietary electrolyte formula to maintain a robust 3.0V discharge platform even at -55℃.

With a high nominal capacity of 220mAh, the CR2032D is the definitive choice for engineers requiring long-term reliability in arctic, high-altitude, and cold-chain logistics sectors.

Technical Specifications of CR2032D 3V 220mAh 

D” Series Low-Temperature Resistant primary lithium button cell 

主要な性能上の優位性

1. Specialist Low-Temperature Electrolyte (-55℃)

The “D” designation identifies our technical breakthrough in electrolyte chemistry. Unlike consumer-grade cells, the CR2032D prevents internal resistance spikes in extreme cold. It provides reliable pulse current and steady voltage at -55℃, ensuring that wireless transmitters and sensors function without interruption in sub-zero climates.

2. High Capacity & Energy Density (220mAh)

Optimized internal construction allows for a consistent 220mAh capacity within the standard 2032 footprint. This high energy density reduces the Total Cost of Ownership (TCO) by extending maintenance intervals and battery replacement cycles for remote devices.

3．優れた気密性

アップグレードされたステンレス鋼製ケースと特殊な耐寒性ガスケットを採用することで、CR2032Dは優れた漏れ防止性能を発揮します。変動する大気圧や厳しい温度サイクル下でも構造的な強度を保ち続けます。.

4. 10年間の保存寿命

Utilizing high-purity manganese dioxide and ultra-stable lithium, this battery retains over 95% of its capacity after 5 years of storage and remains operational for up to 10年間, making it ideal for emergency backup and “set-and-forget” infrastructure.

Critical Industrial Applications

The CR2032D is specifically qualified for sectors where environmental failure is not an option:

• コールドチェーン物流： Temperature data loggers for vaccines, biologics, and frozen pharmaceutical transport.
• Aerospace & High-Altitude: Instrumentation, localized memory backup, and emergency transmitters for aviation and weather balloons.
• 産業用IoT： Wireless sensors, asset trackers, and structural monitors located in outdoor sub-arctic or high-latitude regions.
• 自動車技術： Advanced Tire Pressure Monitoring Systems (TPMS) and smart keys operating in extreme northern climates.
• Military & Defense: Tactical communication devices and field sensors requiring reliable low-temp start-up.

よくある質問

Q: What is the difference between CR2032 and CR2032D?

A： ザ・ “D” series is a technical variant specifically optimized for low-temperature resistance. While a standard CR2032 is typically rated for -20℃ to 60℃, the CR2032D extends the lower limit to -55℃, providing stable power where standard cells would experience voltage collapse.

Q: Is the CR2032D 220mAh compatible with standard holders?

A： Yes. The physical dimensions (20mm* 3.2mm) are identical to a standard CR2032. It is a “drop-in” upgrade for any device that requires enhanced reliability in cold-weather conditions.

Q: Can you provide the discharge curve for sub-zero testing?

A： Absolutely. As a professional B2B partner, we provide complete technical datasheets, including discharge curves at -55℃, and room temperature, to support your engineering validation.
