LiFePO4 forklift batteries typically operate safely from -20°C to 60°C (-4°F to 140°F) and should be charged within 0°C to 45°C (32°F to 113°F). Charging below freezing risks lithium plating, permanently damaging the battery, while high temperatures accelerate chemical degradation, reducing lifespan and performance. Following manufacturer guidelines and maintaining controlled environments is essential for optimal safety and battery longevity.
What Is the Recommended Operating Temperature Range for LiFePO4 Batteries?
LiFePO4 batteries perform best within a discharge temperature range from -20°C to 60°C (-4°F to 140°F), allowing them to function reliably in diverse industrial environments.
What Charging Temperature Range Should Be Observed?
Charging should only be done between 0°C and 45°C (32°F to 113°F) to prevent lithium plating and thermal stress that could harm battery cells.

How Do Low Temperatures Affect Battery Performance?
Charging below 0°C can cause lithium plating on the anode, resulting in permanent capacity loss and safety risks. Discharging at low temperatures thickens the electrolyte, reducing efficiency and runtime.
What Are the Effects of High Temperatures on Batteries?
High temperatures during charging can overheat and damage cells, while operating at elevated temperatures accelerates chemical degradation, lowering overall capacity and shortening battery life.
