Насколько велика может быть кнопочная батарейка? Power Glory предлагает размеры от 9,5 мм до 38 мм.
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.
Продуктовая линейка компании Power Glory (тикер: 920237) начинается с крошечной батарейки CR920 и охватывает вплоть до CR3832 — батарейки диаметром 38 мм и ёмкостью 850 мА·ч. Этот широкий ассортимент, охватывающий от самых маленьких до самых крупных моделей, отражает глубокую техническую экспертизу, которую компания наработала за более чем двадцать лет сосредоточенного внимания к сфере литиевых микропитательных источников.
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%.
Малые размеры не оставляют места для избыточности. По мере уменьшения объёма любые допуски по размерам, погрешности сборки или примеси — будь то материалы катода, электролит, уплотнительное кольцо или корпус — усиливаются в геометрической прогрессии. Способность обеспечить стабильное серийное производство батарейки размером Φ9,5×2,0 мм по сути является подтверждением двойной компетенции компании — как в области научно-исследовательских разработок, так и в сфере производства.
II. Широкий спектр: результат обширной продуктовой линейки
Взгляд на спецификацию серии CR компании Power Glory раскрывает огромное разнообразие моделей: от CR920, CR927, CR1025, CR1216, CR1220, CR1225, CR1616, CR1620 и CR1632 через CR2016, CR2025, CR2032 и CR2050, далее — CR2320, CR2325, CR2330, CR2335, CR2354, CR2430, CR2450, CR2477 и CR3032, вплоть до самой крупной модели — CR3832. Одна лишь серия CR насчитывает 23 различных варианта, рассчитанных на работу при стандартной температуре.
Насколько широк этот продуктовый спектр? Диаметры варьируются от 9,5 мм до 38,0 мм — разница в четыре раза;
Толщины колеблются от 1,6 мм (CR1216/CR1616/CR2016) до 7,7 мм (CR2477);
Емкости варьируются от 20 мАч (CR920) до 1000 мАч (CR2477) — разница в пятьдесят раз.
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. Требовательные условия эксплуатации, стабильная отдача энергии
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:
Устойчивость к экстремальным температурам: серия CR/HT для сверхвысоких температур способна работать в диапазоне от −40 °C до 125 °C. Эти батарейки специально разработаны для таких приложений, как системы контроля давления в шинах (TPMS) — устройств, устанавливаемых непосредственно на ступицы колёс, где им приходится выдерживать как сильное нагревание, так и центробежные силы. В то же время серии CR‑T и BR (литий‑углеродный монофторид) охватывают диапазон температур от −40 °C до 85 °C. Такой широкий температурный спектр позволяет этим монетным батарейкам выходить за пределы климатически контролируемых помещений и применяться в автомобильной, промышленной и полевой сфере.
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. Маленькие компоненты — большие обязанности
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.
Масштаб производства: прочная основа для поставок
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.
Стандартизация — в основе: установление отраслевого эталона
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.
Комплексная система, закладывающая прочную основу для качества автомобильного уровня
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.
Комплексное снижение рисков и обеспечение безопасности на всех этапах жизненного цикла
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.
