　　Precautions for using 18650 lithium ion battery cell electric vehicles

　　Now when people choose electric vehicles, many people choose 18650 lithium ion battery cell electric vehicles, but they do not know how to maintain them. So today I will tell you how to maintain lithium batteries.

　　1. Lithium-ion batteries generally have a service life of 3-6 years, which is twice that of conventional lead-acid batteries. The operating environment of lithium-ion batteries has a charging temperature of 0c~40c and a discharge temperature of -20c~40c.

　　2. The number of new lithium-ion batteries will show a small amount of power, and it is recommended that users fully charge them before use. Since the new rechargeable battery has a part of the battery storage, the initial charging time of the battery is relatively short, and the charging head displays a signal light for charging. There's a special hint here that you don't have to believe that the lithium-ion battery charges for up to 12 hours, implementing phone rumors to ensure but not stress protection.

　　3. Lithium-ion batteries have no memory and can be used at any time. However, it must be noted that lithium-ion batteries cannot be overcharged or discharged. Overcharging and discharging will cause very large volume damage. When the battery car is prompted to use low power, it needs to start charging immediately.

　　4. In normal applications, newly charged lithium-ion batteries should be disabled for 30 minutes before use to ensure stable performance.

　　5. When the electric vehicle is not used for a long time, the battery will be removed and stored in a dry and cool place, and charged every two months, up to 80%, and does not need to be fully charged. In addition, in order to prevent metal materials from contacting the positive and negative electrodes of the battery, it is not necessary to mix the rechargeable battery with metal objects, which may cause short circuit failure, harm the rechargeable battery or even be dangerous.

　　6. Do not knock, shake, step on, modify or expose the battery to sunlight. Do not place rechargeable batteries near microwave ovens, high voltages, etc. Use regular and matching 18650 lithium ion battery cell chargers to charge the batteries, and do not use inferior chargers.
