STORAGE AND MAINTENANCE
STORAGE AND MAINTENANCE
This Portable Power Station contains lithium-ion batteries. Lithium-Ion rechargeable batteries require routine maintenance and care in their use and handling. Read and follow the guidelines in this document to safely use Lithium-Ion batteries and achieve the maximum battery life span. Rechargeable Lithium-Ion batteries have a limited life and will gradually lose their capacity to hold a charge. This loss of capacity (aging) is irreversible. As the battery loses capacity, the Portable Power Station run time decreases. Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in use or while in storage.
Tips for storage: 1. Always store in clean, dry and well-ventilated area where the ambient temperature is 77°F ±9°F (25 ° C ±5 ° C) and the relative humidity does not exceed 75%. 2. Avoid contact with corrosive substances. 3. Keep Portable Power Station away from fire and heat. 4. Keep Portable Power Station away from water and moisture.
Recommendation for maintenance while in storage: Every 3~6 months in storage: 1. At 77°F ±9°F (25 ° C ±5 ° C) ambient temperature, charge the Portable Power Station to full. 2. Then discharge battery to empty using the AC output ports. 3. And finally charge the product to 45%-55% SoC.
NOTICE When the Portable Power Station shuts down due to low battery voltage, the user must charge the Portable Power Station within 30 days, otherwise it will cause irreversible damage to the battery.
