Quanto può essere grande una batteria a bottone? Power Glory offre dimensioni che vanno da 9,5 mm a 38 mm.
How small is a coin cell battery? The smallest coin cell CR920PH produced by Power Glory measures just 9.5 mm in diameter, 2.0 mm in thickness, and weighs a mere 0.5 grams—so inconspicuous that it would go virtually unnoticed when mounted on a motherboard.
Yet, it is precisely this “infinitesimally small” battery that serves as the ultimate test of a company’s “grand capabilities.” As a battery shrinks in size, the requirements for materials, packaging, consistency, and reliability become nearly demanding to the point of severity; with space compressed to the millimeter scale, every increment of performance must be “wrested” from the manufacturing process itself.
Il portafoglio prodotti di Power Glory (codice azionario: 920237) parte da questa minuscola cella CR920 e si estende fino alla CR3832—una batteria con un diametro di 38 mm e una capacità di 850 mAh. Questa vasta gamma di prodotti, che va dalla più piccola alla più grande, testimonia la profonda competenza tecnica che l’azienda ha sviluppato nel corso di oltre vent’anni di dedizione esclusiva al settore delle micro-sorgenti di energia al litio.

I. Compact Size: A Testament to Both R&D and Manufacturing Prowess
The CR920 measures 9.5 mm in diameter and 2.0 mm in thickness, with a nominal capacity of 20 mAh and a total weight of just 0.55 grams. Within such a confined volume, Power Glory has achieved a nominal voltage of 3V and a maximum pulse current of 5mA, while utilizing unique encapsulation technology to keep the annual self-discharge rate below 2%.
Le dimensioni ridotte non lasciano spazio a margini di errore. Con la diminuzione del volume, l’impatto di eventuali tolleranze dimensionali, problemi di precisione nell’assemblaggio o impurità—presenti nei materiali del catodo, nell’elettrolita, nella guarnizione di tenuta e nella custodia—si amplifica esponenzialmente. La capacità di realizzare in modo stabile e su scala industriale una batteria dalle dimensioni Φ9,5×2,0 mm è, in fondo, la dimostrazione delle doppie competenze dell’azienda in ambito di ricerca e sviluppo e di produzione.
II. Un ampio spettro: il risultato di un’estesa gamma di prodotti
Esaminando la scheda tecnica della serie CR di Power Glory emerge una vasta varietà di modelli: dalla CR920, CR927, CR1025, CR1216, CR1220, CR1225, CR1616, CR1620 e CR1632, passando per la CR2016, CR2025, CR2032 e CR2050, proseguendo con la CR2320, CR2325, CR2330, CR2335, CR2354, CR2430, CR2450, CR2477 e CR3032, fino ad arrivare al modello più grande, la CR3832—la sola serie CR comprende ben 23 diversi modelli progettati per funzionare a temperatura ambiente.
Ma quanto è ampio questo spettro di prodotti? I diametri vanno da 9,5 mm a 38,0 mm—una variazione di quattro volte;
Gli spessori oscillano da 1,6 mm (CR1216/CR1616/CR2016) a 7,7 mm (CR2477);
Le capacità variano da 20 mAh (CR920) a 1000 mAh (CR2477), con una differenza di cinquanta volte.
Yet, coin-type batteries represent only a portion of Power Glory’s “eight core lithium battery product” portfolio. This lineup includes lithium-manganese coin cells (standard CR series, as well as wide-temperature CR-HT, CR-D, and CR-T series), lithium-carbon monofluoride (BR) coin cells, rechargeable lithium-aluminum alloy (ML) coin cells, and lithium-ion supercapacitors (LSC series). Complemented by cylindrical lithium-manganese batteries, soft-pack lithium-manganese batteries, and custom battery assembly services, these offerings form a comprehensive product matrix—spanning from micro-sized to cylindrical, primary (non-rechargeable) to rechargeable, and individual cells to complete power solutions. Power Glory ensures that no matter how much space is allocated within a device, customers can always find the perfect fit; the sheer breadth of this product family inherently simplifies the selection process.

III. Condizioni operative impegnative, potenza di uscita costante
Scaling up in size is not merely an increase in dimensions; it represents an expansion of performance boundaries. The smaller the device and the more extreme the operating environment, the more effectively a battery’s “true mettle” is put to the test:
Resistenza alle temperature estreme: la serie CR/HT ad altissima temperatura può funzionare in ambienti che vanno da -40 °C a 125 °C. Queste batterie sono progettate specificamente per applicazioni come i sistemi di monitoraggio della pressione degli pneumatici (TPMS), dispositivi montati direttamente sui mozzi delle ruote, dove devono sopportare sia il calore intenso sia le forze centrifughe. Nel frattempo, le serie CR-T e BR (litio-carbonio monofluoruro) coprono un intervallo di temperatura compreso tra -40 °C e 85 °C. Questo ampio spettro termico consente a queste batterie a bottone di superare gli ambienti interni climatizzati e di essere impiegate in applicazioni automobilistiche, industriali e in campo all’aperto.
Handling Pulse Currents: The high-capacity, high-power CR-P/H&X series offers 10%–20% more capacity than standard models of the same size. With a maximum continuous current of up to 20mA and pulse currents reaching 75mA, they are perfectly suited for the power requirements of devices like car key fobs, RFID tags, GPS units, and Electronic Shelf Labels (ESL)—which typically remain in a low-power, micro-ampere standby state, only to require a sudden burst of power for data transmission.
Ensuring Long-term Reliability: The HT series features an annual self-discharge rate of less than 1%. The ability to both “perform when needed” and “retain power during storage” represents the most fundamental—yet most challenging—promise for any micro-power source.
From motherboard real-time clocks to automotive key fobs; from electronic scales, POS terminals, and digital watches to medical instruments; and from smart home systems to data transmission for photovoltaic installations and natural gas pipelines—the application portfolio of Power Glory coin-cell batteries serves as an “invisible power map” for the era of the Internet of Things (IoT).
