ER17335M 2/3A 3.6V Lithium Thionyl Chloride Battery – High Power, Spiral-type Design, Reliable Performance, Long Life.
The ER17335M is a high-performance, spiral-wound 3.6V Lithium Thionyl Chloride (Li-SOCl₂) battery, specifically designed for applications requiring high pulse current, extended operating life, and exceptional reliability. With a nominal capacity of 1700mAh and energy density up to 450Wh/kg, it is ideal for demanding industrial, IoT, and high-drain electronic applications.
Engineered to perform in extreme conditions from -55°C to +85°C, the ER17335M maintains a stable output voltage with minimal self-discharge (<1% per year at 25°C), offering a shelf life of over 10 years under optimal storage. Its advanced lithium metal anode and carbon-thionyl chloride cathode ensure consistent performance during both continuous and pulse discharge. Certified to UN38.3, UL, and CE standards, this non-rechargeable lithium cell is safe for global transportation and industrial use.
All SUNJ batteries are designed to withstand reasonably foreseeable misuse and are tested in compliance with international performance, safety, and transport regulations.
