Wie groß kann eine Knopfzellenbatterie sein? Power Glory bietet Größen von 9,5 mm bis 38 mm an.

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.

Das Produktportfolio von Power Glory (WKN: 920237) beginnt mit dieser winzigen CR920-Zelle und reicht bis hin zur CR3832 – einer Batterie mit einem Durchmesser von 38 mm und einer Kapazität von 850 mAh. Diese umfangreiche Produktpalette, die vom Kleinsten bis zum Größten reicht, spiegelt das tiefgreifende technische Know-how wider, das das Unternehmen in über zwei Jahrzehnten intensiver Spezialisierung auf den Bereich der Lithium-Mikrostromquellen erworben hat.

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%.

Kleine Abmessungen lassen keinen Spielraum für Unnötiges. Mit sinkendem Volumen verstärken sich die Auswirkungen jeder Maßtoleranz, jeder Montagepräzisionsabweichung oder jeder Verunreinigung – sei es im Kathodenmaterial, im Elektrolyten, im Dichtungsring oder im Gehäuse – exponentiell. Die Fähigkeit, eine Batterie mit den Maßen Φ9,5×2,0 mm stabil und in großen Stückzahlen zu produzieren, ist im Grunde ein Beweis für die doppelte Kompetenz eines Unternehmens in Forschung und Entwicklung sowie in der Fertigung.

II. Ein breites Spektrum: Das Ergebnis einer umfassenden Produktreihe

Ein Blick auf das Datenblatt der CR‑Serie von Power Glory offenbart eine riesige Modellvielfalt: von der CR920, CR927, CR1025, CR1216, CR1220, CR1225, CR1616, CR1620 und CR1632 über die CR2016, CR2025, CR2032 und CR2050, weiterhin die CR2320, CR2325, CR2330, CR2335, CR2354, CR2430, CR2450, CR2477 und CR3032 bis hin zum größten Modell, der CR3832 – allein diese CR‑Serie umfasst 23 unterschiedliche Modelle, die für den Betrieb bei Normaltemperatur ausgelegt sind.

Wie breit ist dieses Produktspektrum tatsächlich? Die Durchmesser reichen von 9,5 mm bis 38,0 mm – eine vierfache Spanne;

Die Dicken variieren von 1,6 mm (CR1216/CR1616/CR2016) bis zu 7,7 mm (CR2477);

Die Kapazitäten reichen von 20 mAh (CR920) bis zu 1000 mAh (CR2477) – eine fünfzigfache Differenz.

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. Anspruchsvolle Betriebsbedingungen, konstante Leistungsabgabe

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:

Resilienz gegenüber extremen Temperaturen: Die CR/HT-Serie für ultrahohe Temperaturen kann in Umgebungen von -40 °C bis 125 °C betrieben werden. Diese Modelle sind speziell für Anwendungen wie Reifendrucküberwachungssysteme (TPMS) konzipiert – Geräte, die direkt an den Radnaben montiert werden und sowohl starker Hitze als auch Zentrifugalkräften standhalten müssen. Gleichzeitig decken die Serien CR-T und BR (Lithium-Kohlenstoff-Monofluorid) einen Temperaturbereich von -40 °C bis 85 °C ab. Dieses breite thermische Spektrum ermöglicht es diesen Knopfzellen, über klimatisierte Innenräume hinaus in Automobil-, Industrie- sowie Außenanwendungen eingesetzt zu werden.

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).

IV. Kleine Komponenten, große Verantwortung

As tiny, easily overlooked components within a device, button batteries carry a critical mission: they must remain functional even when the main power supply is cut off. Power Glory meets this rigorous demand for reliability through a comprehensive system encompassing R&D, manufacturing, standardization, quality control, and risk management.

Fertigungsskalierung: Eine solide Grundlage für die Lieferfähigkeit

Founded in 2004, Power Glory operates an R&D and manufacturing base spanning over 100 mu (approx. 6.7 hectares), supported by a professional team of approximately 650 employees and a monthly production capacity exceeding 66 million units. With about 60% of its products exported to markets including the United States, Germany, Sweden, Japan, South Korea, and India, the company has long provided ODM services to internationally renowned brands, demonstrating a robust capability for large-scale, global delivery.

Standardisierung im Mittelpunkt: Setzung des Branchenmaßstabs

Power Glory has participated in the drafting of five national standards, including “Primary Batteries – Part 1: General” (GB/T 8897.1-2021). As a vice-chair member of the China Lithium Battery Association, the company leverages its technical expertise to help shape industry standards.

Ein umfassendes System, das eine solide Grundlage für Automobilqualität legt

Power Glory holds certifications for ISO 9001, ISO 14001, ISO 45001, and the IATF 16949 automotive quality management system. It has been recognized as a National High-Tech Enterprise, a “Little Giant” firm (specializing in niche markets with cutting-edge technologies), and a “Green Factory” by the Ministry of Industry and Information Technology. To date, the company holds 91 patents—comprising 16 invention patents, 74 utility model patents, and 1 international patent—driving product upgrades through continuous innovation.

Umfassende Risikominderung und durchgängige Sicherheitsgarantie

Power Glory’s products are covered by a $5 million global product liability insurance policy from CHUBB, providing risk protection across the entire lifecycle—from R&D to end-use—to ensure the safety of customers worldwide.

The history of Power Glory’s products is a chronicle of innovation, defined by the successful mastery of increasingly demanding requirements: smaller sizes, broader operating ranges, and resilience in more extreme environments. For over two decades, the company has remained steadfastly focused on miniature lithium power sources. In an era of the “Internet of Everything,” where devices are becoming smaller, thinner, and deployed in increasingly challenging environments, the company that can provide a comprehensive range of millimeter-scale power sources—capable of operating under diverse conditions with reliable delivery—effectively holds the “heart” of the smart device era.
