The Monitor Lithium Battery from Sum Electronics Technology Co., Ltd. is a specialized low-temperature Li-Ion cell designed to operate reliably in extreme cold, from -50 to -20 degrees Celsius. This model (18650-2S) measures 18x36x65mm, delivers a capacity of 3000mAh at 7.2V, and is certified to CE, ROHS, UL, FCC, KC, IEC62133, CQC, UN38.3, and MSDS standards for safety and compliance. It is engineered for environments where standard batteries fail, such as outdoor monitoring, remote sensors, and cold-chain tracking systems.
The battery’s chemistry is optimized for cold-weather performance, with discharge capabilities of over 90% of rated capacity at -20°C (0.2C discharge), over 85% at -30°C, and over 80% at -40°C. For extremely low temperatures, it maintains over 30% capacity at -50°C for civil variants and over 50% for specialized models. These specifications make it suitable for industrial, military, medical, and security applications, as well as energy storage and emergency backup systems. The cells are typically packaged in bulk for B2B procurement, with configurations tailored to the buyer’s operational needs.
Primary buyers include manufacturers of instrumentation, robotics, medical devices, and security equipment, as well as providers of energy storage solutions. The battery’s ability to function in harsh climates also positions it for use in arctic exploration and refrigerated logistics. Sourcing terms such as incoterms, lead times, and packaging formats are confirmed directly with Sum Electronics Technology Co., Ltd., as these details are not specified in the listing. The supplier’s focus on low-temperature reliability sets this product apart from standard lithium-ion alternatives.

Before ordering, verify the battery’s exact discharge performance at your required operating temperature, as the listing provides ranges but not precise values for all variants. Confirm whether the civil, specialized, or extremely low-temperature model best suits your application, as their performance at -50°C differs significantly. Request a sample for independent testing if your use case demands strict adherence to capacity or voltage thresholds.
Logistics details such as lead time, incoterms (e.g., FOB, CIF), and packaging formats (e.g., bulk, palletized, or custom) are not specified in the listing. Sum Electronics Technology Co., Ltd. should provide these terms upon request, along with any minimum order quantities (MOQ) or bulk pricing structures. Clarify whether the supplier can accommodate specific shipping requirements, such as UN38.3-compliant packaging for air transport.
Quality checks should include verifying the battery’s certifications (CE, ROHS, UL, etc.) and requesting test reports for low-temperature performance. Conduct an incoming inspection to confirm dimensions, weight, and voltage match the specifications. For critical applications, arrange third-party testing to validate the battery’s discharge capacity at your intended operating temperature. Ensure all documentation, including MSDS and UN38.3 certificates, is provided for compliance with import and safety regulations.
