What are the precautions for the use and maintenance of lithium-ion batteries

1. The discharge current must not exceed the maximum discharge current specified by the battery. Excessive current discharge will cause a sharp decrease in capacity and cause the battery to over-discharge and expand. 2. Discharge temperature: The battery must be discharged within the operating temperature range specified in the manual. When the surface temperature of the battery exceeds 60 degrees, it should be suspended until the battery is cooled to room temperature. 3. Over-discharge: Over-discharge will cause devastating damage to the battery, so it is best not to make the voltage of the single battery lower than 3.7V when discharging. Battery storage section The battery should be stored in a cool environment. When storing the battery for a long time, it is recommended to place it in an environment with a temperature of 10-25 and no corrosive gas. During long-term storage, the battery is charged and discharged every 3 months to maintain battery activity and ensure that the voltage of each cell is within 3.85V. Finally, if a battery is not going to be used for a short period of time, remember not to fully charge it before storing it. This will easily cause battery swelling during storage. The best storage method is that the best storage voltage is about 3.8V for a single chip. When the battery catches fire on the charging cabinet, first cut off the power supply of the equipment; quickly observe the storage location of asbestos gloves and asbestos blanket nearby, use asbestos gloves or tongs to remove the burning lithium ion battery from the charging cabinet rack, and place it on the ground or fire-fighting sand In the bucket. Cover the flames of lithium-ion batteries on the ground with an asbestos blanket. The fire-fighting sand was buried on the asbestos blanket to isolate the air and suffocate it. Do not use dry powder to extinguish the fire, because dry powder will cover a large amount of dust on solid metal chemical fires, and it has corrosive uses for equipment and pollutes the space. Carbon dioxide does not pollute the space and corrode the machinery, but it can only achieve instantaneous suppression of flames. It needs to be used in conjunction with sand and asbestos blankets.
