Hcb Li-SOCl2 Cylindrical Battery, ER18505, 3.6V, 4000mAh

The HCB ER18505 is a high-performance 3.6V Lithium Thionyl Chloride (Li-SOCl?) primary battery engineered for long-duration, stable power delivery in demanding industrial, commercial, and remote-operation applications. Designed with advanced chemistry and precision manufacturing, it offers exceptionally high energy density, ultra-low self-discharge, and excellent reliability, making it one of the most preferred cells for long-life electronic devices. With a typical capacity of around 4000 mAh, the ER18505 cell supports continuous power supply for many years—often exceeding 8 to 10 years depending on load and operating conditions. Its cylindrical design, rugged stainless-steel housing, and hermetic sealing ensure safe operation even in challenging environments such as extreme temperatures, high-vibration machinery, or outdoor installations. The ER18505 battery is optimized for low-current, long-duration applications such as smart metering, asset tracking, IoT devices, data loggers, security systems, emergency transmitters, and industrial controllers. Its chemistry provides a stable 3.6V output, maintaining consistent performance across a wide operating temperature range from -55 to +85 Deg.C—making it suitable for both cold-storage environments and high-heat industrial locations.
