A tiny battery, barely thicker than a finger, can silently operate in smart meters for years without requiring replacement, a testament to the continuous advancements in lithium battery technology. Smart electricity, water, and gas meters are replacing traditional mechanical meters worldwide, enabling precise measurement and remote management of energy usage.

The core bottleneck for the long-term stable operation of these smart meters lies in the lifespan and reliability of the batteries that power them. To address this industry-wide challenge, Power Glory's CR123A high-capacity lithium-manganese dioxide battery, with its superior energy density and low self-discharge rate, is becoming the "long-lasting powerhouse" of the smart metering industry.

The challenge of long-term power supply for smart meters

With the widespread adoption of IoT technology in energy management, the global smart meter market is experiencing explosive growth. These meters are often installed in confined spaces or harsh environments, placing extremely stringent demands on their power supply. Traditional alkaline batteries cannot meet the maintenance-free operation requirements of smart meters, which can last for years or even decades. Not only do they have limited energy density, but their performance also degrades dramatically in extreme temperatures.

Smart meters require a "heart" that can last throughout their entire lifecycle. This "heart" must be robust enough to withstand temperatures as cold as -40°C and as hot as +70°C, while maintaining an annual self-discharge rate of less than 2%. The industry once relied heavily on imported batteries. Through continuous technological research, Power GLory has gradually mastered the core technology of long-lasting lithium batteries.

The core advantages of CR123A batteries

Power GLory's CR123A lithium-manganese dioxide battery utilizes a lithium-manganese dioxide chemistry, boasting a nominal voltage of 3V and a nominal capacity of 1500mAh, far exceeding similar products on the market.

This battery boasts an astonishing energy density of 280Wh/kg, approximately twice that of a typical alkaline battery. This means it can store and release more energy within the same volume.

A wide operating temperature range (-40°C to +70°C) allows it to withstand a wide range of harsh environments, ensuring the proper operation of smart meters from the harsh winters of northern China to the scorching summers of southern China.

Power GLory's CR123A battery utilizes high-performance cathode materials and an optimized electrolyte formula, resulting in a more stable discharge voltage and effectively extending the lifespan of smart meters.

This battery utilizes a special sealed structure to effectively prevent electrolyte leakage, resulting in an annual self-discharge rate of ≤2%, and can be stored at room temperature for over 10 years with limited capacity degradation.

Providing lasting power for smart meters

In practical applications, Power GLory's CR123A batteries have performed exceptionally well. Smart meters equipped with these batteries have maintained a stable voltage above 3V during long-term testing, ensuring the continuity and accuracy of metering data.

For power companies, this means significantly reduced operations and maintenance costs. Smart meters are often installed in locations like electrical wells and distribution boxes, where frequent maintenance is inconvenient. Battery life directly impacts maintenance costs and customer satisfaction. Without the worry of data loss due to battery depletion, operational efficiency is significantly improved.

In addition to smart meters, these batteries are also widely used in various energy metering scenarios, including water, gas, and heat meters, becoming an indispensable energy source for the public utility sector.

Continuous innovation and quality control

Power Glory invests no less than 5% of its total revenue in R&D annually. The company has established a three-tiered R&D system: basic research, pilot testing, and mass production. Through in-depth collaboration with universities, the company rapidly transforms laboratory findings into competitive advantages on the production line.

In production, Power Glory has introduced fully automated production lines and visual inspection systems, enabling complete automation from raw material input to finished product packaging, ensuring industry-leading product consistency.

As of June 2025, Power Glory had applied for nearly 100 domestic and international patents, establishing a solid technological barrier. This commitment to technological innovation and quality control ultimately translates into reliable product performance in the market.

Energy Solutions in the Internet of Things

With the rapid growth of global IoT connections, demand for miniaturized, long-life power solutions continues to grow. Smart meters, a key IoT application, represent just the tip of the iceberg in terms of demand for high-performance batteries.

Power Glory's CR123A batteries have expanded beyond smart meters to include automotive electronics, smart security, medical equipment, and other fields. They can be found in tire pressure monitoring systems, smoke alarms, remote monitoring systems, and more.

Over the next five years, the number of IoT devices worldwide will grow exponentially. As the "energy core" of these devices, high-performance primary lithium batteries hold a promising market prospect. The company is actively developing a global strategy and has already secured supply agreements with numerous international smart hardware manufacturers. Its products are exported to Europe, North America, and other regions, demonstrating the quality advantages of Made in China in the global market.

In the IoT era, batteries, while small, are fundamental elements supporting the interconnectedness of everything. Power Glory's success demonstrates that through continuous technological innovation, Made in China is shifting from following to keeping pace with and even leading the way, providing a Chinese solution for global energy reform.
