Due to the use of lithium-ion batteries in portable power stations, the unique chemical properties of lithium-ion batteries require specific environmental conditions. Lithium batteries contain electrolytes that are sensitive to temperature; excessive heat can cause the electrolyte to decompose, producing gases and increasing internal pressure, which can lead to safety issues. On the other hand, extremely low temperatures can reduce the chemical reaction activity inside the battery, preventing it from discharging.

1. Charging Temperature: 0-40°C/32-104°F (NCM Lithium Battery) / 0-45°C/32-113°F (LiFePO4 Battery)

Do not charge below 0°C/32°F to prevent irreversible damage to the battery due to low temperatures.

2. Discharging Temperature: -10-40°C/14-104°F (NCM Lithium Battery) / -10-45°C/14-113°F (LiFePO4 Battery)

Do not use the product in environments above 40°C/104°F (for NCM Lithium Battery products) / 45°C/113°F (for LiFePO4 Lithium Battery products) or below -10°C/14°F, to prevent irreversible damage caused by low or high temperatures, as well as the danger of overheating.

3. Storage Temperature: -20-45°C/-4-113°F (within 3 months)

For long-term storage (over 3 months), the battery should be maintained at 50% of its rated capacity (charge once every 3 months to prevent deep discharge and damage). It should be stored in a dry, cool place, with a temperature range between 0°C/32°F and 40°C/104°F, avoiding contact with corrosive substances and keeping it away from fire sources and heat.

4. Environmental Humidity: 0~60% RH (non-condensing)

Excessive humidity can reduce the insulation performance. If condensation forms and water droplets fall onto the circuit board, it could cause a short circuit, leading to malfunction."
