Long-Term Storage
After the battery is charged, it should be used as soon as possible to avoid loss of usable capacity due to self-discharge. If storage is required, the battery needs to be stored in a low SOC state. The recommended storage conditions are 30%~40%SOC 0~25℃ ≤60%RH.
Transportation
Battery for shipping should be packed in boxes with the SOC of 30%~40%. The severe vibration, impact, extrusion, sun and rain should be prevented during shipping. Applicable methods of transportation include truck, train, ship, airplane, etc.
Operation Precautions
• It is forbidden to inversely charge. Correctly connect the positive and negative poles of the battery, and reverse charging is strictly prohibited.
• It is forbidden to over-discharge. During the normal use of the battery, in order to prevent over-discharge, the battery should be charged regularly to maintain the voltage above 2.8 V
• It is strictly forbidden to immerse the battery in water. When it is not in use, it should be placed in a cool and dry environment.
• It is forbidden to use and leave the battery next to heat and high temperature sources, such as fire, heater, etc.
• Please use a special charger for lithium-ion batteries when charging.
• During usage, it is strictly prohibited to reverse the positive and negative terminals of the battery.
• Do not throw the battery in the fire or heater.
• It is forbidden to use metal to directly connect the positive and negative terminals of the battery to short-circuit.
• It is forbidden to transport or store the battery with metal, such as hairpins, necklaces, etc.
• It is forbidden to knock or throw, step on, or bend the battery.
• It is forbidden to directly solder the battery.
• It is forbidden to directly pierce the battery with nails or other sharp objects.
• It is forbidden to use or place the battery under high temperature (under hot sunlight), such as in a car under direct sunlight or in a hot day.
• It is forbidden to use it in places with strong static electricity and strong magnetic fields.
• If the battery leaks and the electrolyte splashes on the skin, clothes, eyes, mouth, nose, etc., immediately wash the affected area with running water and send to a doctor for treatment immediately, otherwise it will cause serious harm to the human body.
• If the battery emits peculiar smell, heat, discoloration, deformation, or any abnormality during use, storage, or charging, immediately remove the battery from the device or charger and stop using it.
