¿Qué tamaño puede tener una batería de botón? Power Glory ofrece tamaños que van desde 9,5 mm hasta 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.
La cartera de productos de Power Glory (código bursátil: 920237) comienza con esta diminuta pila CR920 y se extiende hasta la CR3832, una batería de 38 mm de diámetro y 850 mAh de capacidad. Esta amplia gama de productos, que abarca desde los más pequeños hasta los más grandes, refleja la profunda experiencia técnica que la empresa ha desarrollado durante más de dos décadas dedicadas exclusivamente al campo de las microfuentes de energía de 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%.
El tamaño reducido no deja margen para la redundancia. A medida que el volumen disminuye, el impacto de cualquier tolerancia dimensional, problema de precisión en el ensamblaje o impureza —desde el material del cátodo y el electrolito hasta el anillo de sellado y la carcasa— se magnifica exponencialmente. La capacidad de producir de manera estable y a gran escala una batería de dimensiones Φ9,5×2,0 mm es, en esencia, un testimonio de las dobles capacidades de la empresa en investigación y desarrollo, así como en fabricación.
II. Un amplio espectro: resultado de una extensa línea de productos
Al revisar la hoja de especificaciones de la serie CR de Power Glory se observa una vasta variedad de modelos: desde la CR920, CR927, CR1025, CR1216, CR1220, CR1225, CR1616, CR1620 y CR1632, pasando por la CR2016, CR2025, CR2032 y CR2050, continuando con la CR2320, CR2325, CR2330, CR2335, CR2354, CR2430, CR2450, CR2477 y CR3032, hasta llegar al modelo más grande, la CR3832; solo esta serie CR incluye 23 modelos distintos diseñados para operar a temperatura ambiente.
¿Hasta qué punto es amplio este espectro de productos? Los diámetros oscilan entre 9,5 mm y 38,0 mm, lo que representa una variación de cuatro veces;
Los grosores varían desde 1,6 mm (CR1216/CR1616/CR2016) hasta 7,7 mm (CR2477);
Las capacidades van desde 20 mAh (CR920) hasta 1000 mAh (CR2477), lo que representa una diferencia de cincuenta veces.
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. Condiciones de operación exigentes, potencia de salida constante
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:
Resistencia a temperaturas extremas: La serie CR/HT, diseñada para temperaturas ultraaltas, puede operar en entornos que van desde -40 °C hasta 125 °C. Estas baterías están especialmente concebidas para aplicaciones como los sistemas de monitoreo de presión de neumáticos (TPMS), dispositivos montados directamente sobre los bujes de las ruedas, donde deben soportar tanto el calor intenso como las fuerzas centrífugas. Por su parte, las series CR‑T y BR (litio‑carbono monofluoruro) abarcan un rango de temperatura de -40 °C a 85 °C. Este amplio espectro térmico permite que estas pilas de botón trasciendan los ambientes interiores climatizados y se adapten a aplicaciones automotrices, industriales y de campo al aire libre.
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. Componentes pequeños, responsabilidades significativas
