Battery Cooling Tech Explained: Liquid vs Air Cooling Systems Updated On Fri, May 9th, 2025 by Saurenergy Electric batteries must be kept within a narrow temperature range (typically about 20–40°C) for peak performance and safety. In fact, research shows Li-ion batteries live about 20 percent longer at 20°C vs 30°C, and life drops by about 40 percent at 40°C. Hot spots in a pack can trigger runaway and fires. Thus thermal management […] Read more
