The ideal temperature range for storing energy storage batteries, particularly lithium-ion and lithium-iron phosphate (LiFePO4) batteries, varies slightly based on the type but generally includes the following ranges:
- Lithium-ion Batteries: For storage, a temperature range between -20°C to 25°C (-4°F to 77°F) is recommended. Storage at lower or higher temperatures can impact performance and lifespan. For optimal operation, the temperature should be between 15°C to 35°C (59°F to 95°F).
- Lithium-iron Phosphate (LiFePO4) Batteries: The recommended storage temperature range is 0°C to 35°C (32°F to 95°F). Operating and charging temperatures vary slightly, with charging ideally between 0°C to 55°C (32°F to 131°F) and discharge between -20°C to 55°C (-4°F to 131°F).
- General Recommendations: Avoiding extreme temperatures is crucial. Temperatures below 0°C (32°F) can reduce capacity and efficiency, while temperatures above 60°C (140°F) can lead to accelerated aging and safety risks. Maintaining batteries in a cool, dry environment away from direct sunlight and heat sources is essential for optimal storage.
