Driven by the rapid development of "smart cities" and "digital energy", the market demand for IoT terminal devices such as smart water meters and gas meters is growing. As the core power supply unit of such equipment, the performance of the battery is directly related to the operating stability and maintenance cycle of the meter. Especially in remote automatic meter reading systems, equipment is usually deployed outdoors or in remote areas, which places extremely high demands on the battery's life, self-discharge rate, and temperature adaptability.
Among many power solutions, CR123A primary lithium batteries have become the preferred choice of smart meter manufacturers due to their high energy density, low self-discharge, and wide temperature range adaptability. Jiangmen Hongli Energy Co., Ltd., as a professional 3V primary lithium battery manufacturer, has provided stable and reliable battery support for many domestic and foreign smart metering equipment manufacturers with its high-quality CR123A products.
Long-lasting power supply, reducing replacement frequency and operation and maintenance costs
Hongli Energy's CR123A battery adopts a lithium-manganese dioxide chemical system, with a capacity of more than 1500mAh and a storage life of more than 10 years. Under the typical power consumption conditions of smart water meters and gas meters, it can stably supply power for 6 to 10 years, greatly reducing the replacement frequency and manual maintenance costs, and helping customers build a low-operation and maintenance energy management system.
Low self-discharge rate to ensure data collection stability
In view of the long-week standby and intermittent working characteristics of AMR/AMI equipment, Hongli Energy has specially optimized the battery's self-discharge control technology. The self-discharge rate of its CR123A product is controlled at ≤1% per month, ensuring that the device can still accurately wake up and send data within a long time interval, effectively avoiding signal interruption or data loss caused by voltage drop.
Wide temperature operation, adaptable to various outdoor environments
Smart meters are often deployed outdoors in underground wells, wall shells or extreme temperature environments, which challenges the temperature resistance of batteries. Hongli CR123A batteries support a wide operating temperature range of **-40℃ to +85℃**, and can operate stably in both the cold winter in the north and the hot summer in coastal cities, ensuring trouble-free power supply for meter reading systems throughout the year.
Improve the certification system to meet global market access
Hongli Energy's CR123A batteries have passed international certifications such as UL, UN38.3, RoHS, and REACH, and meet the standard requirements for export to Europe, North America, and Southeast Asia. At the same time, it supports OEM/ODM customization services and can provide personalized product solutions based on the installation space, voltage characteristics, connection methods, and other requirements of meter manufacturers.
With the continuous expansion of the smart metering market, high-quality battery suppliers are becoming the key for smart meter manufacturers to achieve product differentiation and market competitiveness. Hongli Energy will continue to use its professional R&D and manufacturing capabilities to provide stable and reliable CR123A battery solutions for low-power devices around the world, and jointly promote the implementation and development of smart city energy management systems.
