About Us
Powering the Future with Advanced ER Series Lithium Solutions
Shenzhen Cowon Technology Limited are a specialized manufacturer and supplier dedicated to the research, development, and production of high-performance Lithium Thionyl Chloride (Li-SOCl2) batteries. Focusing exclusively on the ER series chemistry, we provide robust energy solutions designed for the most demanding environments, ranging from extreme cold to high-temperature industrial applications. Our expertise lies in delivering power that combines high energy density with exceptional longevity.
Our core business is built on two pillars: the supply of premium ER series cells (including standard models like ER14250, ER14505, ER17505, ER26500, and the heavy-duty ER34615) and the custom fabrication of battery packs. We go beyond simple cell manufacturing by offering comprehensive processing services, including soldering tabs, wire harnesses, and connector integration (such as 2-pin or Molex plugs). This allows us to create bespoke battery modules that are ready for direct installation into smart meters, GPS trackers, security systems, and memory backup units.
Committed to quality and versatility, we serve a wide array of industries including utility metering, automotive electronics, and industrial IoT. We understand that different applications require different discharge characteristics-whether it is the Capacity Type for long-term low-current drain or the Power Type for high-pulse applications. By leveraging advanced bobbin-type and spiral-wound technologies, we ensure that every battery pack we produce delivers stable voltage and reliable performance throughout its shelf life, making us a trusted partner for global energy needs.
FAQs
What is the standard nominal voltage of your ER series batteries?
All our ER series Lithium Thionyl Chloride (Li-SOCl2) batteries have a standard nominal voltage of 3.6V. This high voltage is a key characteristic of Li-SOCl2 chemistry, making it ideal for replacing multiple lower-voltage batteries in a single compact unit.
Do you only sell individual cells, or can you manufacture battery packs?
We offer both. We supply standard individual ER cells (like ER14250, ER18505, ER34615) for manufacturers, and we also have a professional processing line to create custom battery packs. We can assemble multiple cells in series or parallel to meet your specific voltage and capacity requirements.
What is the expected lifespan of these batteries in a smart meter application?
Due to the ultra-low self-discharge rate (less than 1% per year at room temperature), our ER batteries are designed for long-term use. In typical smart meter applications (low current drain), they can last anywhere from 5 to 10 years, and in some low-drain standby applications, even longer.
Do you provide documentation for shipping and customs?
Yes. We provide all necessary documentation for international shipping, including the MSDS (Material Safety Data Sheet) and UN38.3 Test Summary, ensuring smooth customs clearance for air and sea freight.
What is the difference between "Capacity Type" and "Power Type" ER batteries? A:
Capacity Type (Bobbin): Designed for low current drain and long-term standby (e.g., smart meters, memory backup). They offer the highest capacity but limited pulse current.
Power Type (Spiral): Designed to handle higher continuous currents and high-current pulses (e.g., GPS trackers, two-way radios). They have slightly lower total capacity but superior discharge capabilities.
What kind of processing services do you offer for battery packs?
Our processing capabilities are extensive. We can add:
Soldering: Tabs, pins, or wires (UL certified wires available).
Connectors: Installation of specific plugs (e.g., Molex, JST, 2-pin white connectors) to match your device.
Packaging: Custom PVC heat shrink wrapping or epoxy potting for waterproofing (IP67/IP68).
What is the shelf life of your batteries if stored properly?
Our ER batteries have an excellent shelf life. When stored at recommended temperatures (around 20°C), they can retain over 99% of their capacity per year. We typically guarantee a shelf life of 5 to 10 years, ensuring that stock remains fresh for your production needs.
