18650T 3.7V 2000mAh Li-ion Battery -40°C to 85°C

3.6V 18650 2000MAH lithium ion battery cell with wide range temperature discharge application

Quick view:

• Good rate performance: Can continuously discharge at 5C at room temperature
• Wide range temperature operating range: Operating temperature interval is from - 40°C to 85°C; Can discharge more than 60% of capacity at - 40°C with 0.2C
• Excellent high - temperature (80°C) storage performance
• The battery cell that has been stored at high temperature still has excellent low - temperature discharge performance
• Good cycle performance

Application:

• Electric vehicles (EVs) and hybrid electric vehicles (HEVs)
• Automotive testing equipment

• Aerospace industry :Satellites and space probes/Aerospace ground support equipment

The advantages of wide-temperature batteries are as follows:

Exceptional temperature adaptability

      They operate stably within an extended temperature range, typically from -40°C to 85°C (or even broader for some models). Unlike regular batteries that suffer from severe capacity loss or failure in extreme cold (below -20°C) or heat (above 60°C), wide-temperature batteries maintain functionality in harsh environments such as polar regions, deserts, high-altitude areas, and industrial cabins.

Reliable performance output

• High capacity retention at low temperatures: They can deliver over 60%-70% of their capacity at -40°C (at 0.2C discharge), far exceeding the 20%-30% of conventional batteries, ensuring sufficient runtime for devices in cold conditions.
• Stable charge/discharge efficiency: Even in extreme temperatures, their charge/discharge rates and voltage output remain consistent, preventing device malfunctions or shutdowns caused by unstable power supply

Superior storage and cycle life:

Excellent high-temperature storage recovery: After 1000 hours of storage at 85°C, they can retain over 85% (some models over 90%) of their recoverable capacity, outperforming regular batteries that degrade rapidly under such conditions.

Durable cycle performance: They offer extended cycle life (over 500 cycles) under wide-temperature operations, reducing replacement frequency and maintenance costs.

Enhanced safety:Designed with specialized materials (e.g., high-temperature-resistant electrolytes, low-temperature-tolerant electrodes) and                               structures, they are less prone to leakage, swelling, or short circuits under temperature shocks, minimizing risks of fire or

                       explosion—critical for applications like medical equipment and new energy vehicles.
