For lithium-ion battery storage, keeping cells within -20°C to 25°C (-4°F to 77°F) preserves capacity and minimizes self-discharge, ensuring long-term reliability. Proper storage of lithium batteries is crucial for preserving their performance and extending their lifespan. . Optimal Lithium Battery Temperature Range for Performance and Safety Lithium-ion batteries operate best between 15°C to 35°C (59°F to 95°F) for usage and -20°C to 25°C (-4°F to 77°F) for storage. Maintaining these ranges maximizes efficiency, lifespan, and safety. Exceeding these limits can cause. . Lithium-ion batteries operate and store energy within specific thermal thresholds. But 0°C to 45°C for charging is much stricter, to prevent permanent damage. Here's why: Avoid Heat: Temperatures above 30°C (86°F) speed up chemical reactions inside the battery, causing irreversible capacity loss. Prevent Cold: Below 0°C (32°F). . From an application perspective, the lithium battery temperature range is typically divided into three categories: Normal range: -20°C to 60°C, within which the battery can charge and discharge normally. NFPA 855 outlines ventilation and safety requirements. Store batteries at a temperature of 59°F (15°C). Also, refer to NFPA 70E for further safety guidelines, and ensure proper exhaust ventilation. .
