Do Lithium Batteries Need to Be Heated?
Lithium batteries do not inherently need to be heated under normal operating conditions; however, they may require heating in extremely cold environments to maintain performance and safety. When temperatures drop below 0°C (32°F), lithium batteries can experience reduced capacity and efficiency. Heating helps ensure optimal operation and longevity.
What Is the Ideal Operating Temperature for Lithium-Ion Batteries?
The ideal operating temperature range for lithium-ion batteries is typically between 0°C and 45°C (32°F to 113°F). Within this range, batteries perform optimally, providing reliable power output and longevity. Operating outside this range can lead to diminished capacity, increased self-discharge rates, and potential safety hazards.Ideal Operating Temperature Chart
