コアエンジニアリングの優位性およびB2Bにおける有用性
1. Space-Optimized 1/2 AA Geometry
The CR14250 reduces layout overhead by exactly 50% compared to a standard AA cell, allowing engineers to reduce the enclosure sizes of handheld tools, smart meters, and tracking hardware without forcing a compromise on battery capacity.
2. High-Pulse Capacity via Spiral Design
Unlike bobbin-style cells that suffer from temporary voltage delay or passivation under heavy loading, our CR14250 utilizes a precision spiral-wound inner structure. This design increases the chemical reaction surface area, enabling the battery to cleanly support the instant micro-second current surges required by wireless transceivers and RF modules.
3. Decadal Storage Stability (≤2% Self-Discharge)
Featuring a high-purity lithium metal anode matched with hermetic glass-to-metal sealing technology, internal chemical aging is limited to under 2% annually. Your finished products can remain idle in inventory or run in ultra-low sleep modes for up to a decade and still perform instantly when activated.
4. 極限の耐熱性(−40℃~+70℃)
The battery’s internal organic electrolyte retains stable ionic mobility under freezing outdoor field conditions (-40°C) while resisting high-temperature pressure generation and rapid self-discharge inside unventilated industrial enclosures (+70°C).

よくある質問
Q1: Can a CR14250 battery replace a standard AA battery?
A: No. While they share the same diameter (14.5mm), the CR14250 is exactly half the length (25.0mm vs 50.5mm). Additionally, the CR14250 delivers a 3.0V output, whereas a standard consumer AA battery delivers 1.5V. Using a 3V cell in a circuit designed for 1.5V will cause over-voltage damage to the microprocessors.
Q2: Is the CR14250 battery rechargeable?
A: No. The CR14250 is a . これは安全に再充電することはできません。この電池パックに無理に電流を流そうとすると、内部の密封されたセルシールが破壊され、電解液の漏れや内部短絡、さらには熱暴走を引き起こすおそれがあります。安全に再充電することはできません。無理に電流を流そうとすると、内部の密封構造が破壊され、電解液漏れや内部短絡、さらには熱暴走を引き起こすおそれがあります。
Q3: Why is the ≤2% self-discharge rate crucial for memory backup and smart meters?
A: Industrial smart meters and memory backup circuits spend the vast majority of their lifecycles in ultra-low micro-amp sleep states, waking up for mere milliseconds to log or transmit data. A self-discharge rate of ≤2% ensures that the battery’s energy is preserved for actual device operations over a span of up to 10 years, rather than wasting away internally.
