CR2325D 3V 190mAh 工業用コールドチェーンセンサー向け低温一次リチウム電池
CR2325D：北極圏グレードのパワーハウス――190mAhの耐久性で厳寒に挑む
Where Standard Lithium Fails, the “D” Series Thrives. Engineered for the Edge of Existence: -55℃ to 60℃.
In the critical world of sub-zero logistics and high-altitude exploration, a battery isn’t just a component—it’s a heartbeat. Most lithium coin cells “hibernate” when temperatures drop below -20℃, leading to data gaps and system failures. The CR2325D is the industry’s answer to the extreme.
By integrating a proprietary Low-Temperature Resistant Electrolyte, the CR2325D ensures that your sensors, trackers, and medical devices remain wakeful and precise, even in environments that silence everything else.
「D」シリーズの違い：エンジニアがCR2325Dを指定する理由
1. The -55℃ Thermal Frontier
Standard batteries suffer from “electrolyte sluggishness” in the cold, causing internal resistance to spike. The CR2325D utilizes a specialized molecular lattice that maintains high ion mobility at -55℃. This isn’t just a rating; it’s a guarantee of pulse-current reliability for wireless transmissions (IoT/RF) in arctic climates.
2. 高容量・長寿命（190mAh）
In a slim 23mm* 2.5mm profile, we have packed a massive 190mAh of energy. We didn’t sacrifice longevity for temperature resistance. The CR2325D offers a high-density discharge platform, meaning fewer battery replacements in difficult-to-access remote locations.
3. 10年間の「即時使用可能」な保存期間
With a self-discharge rate of ≤2% annually, the CR2325D is the perfect candidate for emergency backup systems. Store them in a warehouse or keep them inside a dormant device—they remain peak-performance ready for a decade.

FAQ
Q: What makes the CR2325D “low-temperature resistant”?
A： Unlike standard cells, the CR2325D uses a specialized electrolyte formula and a low-impedance internal structure. This allows the battery to maintain a stable voltage platform even at -55℃, whereas standard cells experience voltage collapse below -20℃.
Q: Can the CR2325D be used for high-pulse wireless transmission?
A： Yes. The CR2325D is specifically optimized to handle the brief high-current pulses required for Bluetooth Low Energy (BLE), Zigbee, and NB-IoT, even in extreme cold conditions.
Q: What is the shelf life of the CR2325D?
A： Thanks to the high stability of the Lithium-Manganese chemistry, the CR2325D has a 10年間の保存寿命 when stored at room temperature, losing less than 2% of its capacity per year.
