CP210619 3V 25mAh Ultra-Micro Primary Lithium Manganese Dioxide LiMnO2 Pouch Battery
2.1mm Ultra-Narrow Profile. 0.35g Featherweight Footprint. Precision Micro-Power for Hyper-Compressed Smart Tracking Arrays.
When your hardware blueprint scales down to the size of an active tracking sticker, a wearable medical patch, or an ISO-compliant smart card, conventional coin cells are instantly ruled out due to thickness and diameter limits. The CP210619 3V 25mAh Ultra-Micro Primary Lithium Battery provides the exact structural workaround for next-generation micro-electronics.
Weighing an astonishingly light 0.35g with a profile thickness of 2.1mm and a narrow width of 6.5mm, this non-rechargeable solid-state pouch cell packs a reliable 25mAh capacity. It allows hardware engineers to inject standalone 3V power directly into restricted edge-cavities without adding physical bulk or affecting sleek product design.

Core Engineering Differentiators & B2B Value
1. Ultra-Narrow Form Factor (2.1mm × 6.5mm)
The micro-pouch geometry is optimized for perimeter placements along card borders, linear smart labels, and ultra-slender wearable enclosures. This completely eliminates the layout restrictions found with round button cells.
2. 0.35g Total Weight Optimization
Crucial for disposable clinical diagnostic strips, smart shipping labels, and wearable health patches where excess component mass impacts adhesive reliability or increases global postal weight brackets.
3. Decadal Storage Integrity (≤2% Annual Self-Discharge)
Utilizing high-purity lithium foil chemistry combined with a specialized hermetic seal layer, internal chemical loss remains under 2% per year. This guarantees that devices sitting idle in warehouse logistics or running on long-term standby will wake up with full operational capacity.

Frequently Asked Questions
Q1: Is the CP210619 battery pack rechargeable?
A: No. The CP210619 is a primary (single-use) lithium manganese dioxide battery. It cannot be safely recharged. Attempting to apply charging current will damage the micro-pouch barrier layers, resulting in swelling, electrolyte leakage, or permanent structural damage to your device’s PCB board.
Q2: Why select the CP210619 pouch over a standard CR1220 or CR927 coin cell?
A: Standard coin cells have a rigid metal casing that is at least 2.0mm to 3.2mm thick and requires a surface-mount battery holder, which adds massive vertical height. The CP210619 features a flexible, flat soft-pack layout that can be soldered directly to the board or nested into empty cavities, minimizing your product’s overall Z-axis height.
Q3: How does the ≤2% annual self-discharge rate protect bank cards and smart labels?
A: Smart cards and active RFID tags remain in ultra-low micro-amp sleep modes for 99% of their operational lifecycles, waking up for mere milliseconds to execute an authentication or transmit data packets. A self-discharge rate of ≤2% ensures that almost the entire nominal capacity of 25mAh is preserved for actual device operations over a span of up to a decade, rather than wasting away internally.
