Lithium batteries are sensitive to extreme temperatures, and exposing them to extremely low temperatures can have detrimental effects on their performance and overall lifespan. To prevent damage, many lithium batteries incorporate low-temperature protection systems.
Understanding the temperature limits for lithium batteries is significant for safely using them in equipment that may experience extreme temperatures. The optimal operating temperature range for lithium batteries typically falls between -4°F and 140°F (-20°C to 60°C).
Lithium batteries are highly sensitive to extreme temperatures, especially cold. As a general guideline, temperatures below 0°C (32°F) can significantly impact the performance and lifespan of lithium batteries. When exposed to such low temperatures, the chemical reactions within the battery slow down, leading to reduced capacity and voltage output.
The specific threshold can vary depending on the battery manufacturer and model. By implementing low-temperature protection, lithium batteries are safeguarded from potential harm, such as reduced capacity, increased resistance, or even permanent damage caused by chemical reactions not occurring optimally at low temperatures.
To protect lithium batteries in cold weather, it is recommended to store them in a temperature-controlled environment whenever possible. If you need to use them in cold temperatures, try to keep them insulated and minimize exposure to extreme cold for extended periods.
Low-temperature lithium batteries are used in military equipment, including radios, night vision devices, and uncrewed ground vehicles (UGVs), to maintain operational readiness in cold climates. Part 6. Low-temperature batteries vs. standard batteries Performance in Cold Conditions
