LiFePO4 Battery Storage Temperature Range. LiFePO4 batteries also have a defined storage temperature range that is crucial for preserving their performance and health during periods of inactivity or non-use. The recommended storage temperature for LiFePO4 batteries falls within the range of -10°C to 50°C (14°F to 122°F).
Safe storage temperatures range from 32℉ (0℃) to 104℉ (40℃). Meanwhile, safe charging temperatures are similar but slightly different, ranging from 32℉ (0℃) to 113℉ (45℃). While those are safe ambient air temperatures, the internal temperature of a lithium-ion battery is safe at ranges from -4℉ (-20℃) to 140℉ (60℃).
