Storage and Transportation

The cell must be stored separately in a cool (less than or equal to 25 C) dry area for long-term storage, away from direct sunlight, heated environments and high static environments. The battery must be kept away from children or pets. For storage, a 50% SOC cell stored at 40 C for 1 month, 30 C for 2 months, or 20 C for 3 months can recover greater than or equal to 90% capacity at room temperature using the standard charge and discharge mode. During transport, the positive (+) and negative (-) directions must be checked before packaging, and insulation must be verified to prevent short circuits when wiring boards or wires are connected to the battery. The cell must not be exposed to temperatures outside the specified operating temperature range. When monomers are used for module or component assembly, the first-in, first-out principle should be adopted. The cell must not be soaked or wetted by water or seawater, and must not be placed in microwave ovens or high-voltage containers.
