Brief introduction of 18650 lithium battery repair method and correct use method of lithium battery

18650 lithium battery repair method 1. Take out your 18650 lithium battery after it is used up and treat it with temperature. The battery will greatly shorten the use time when the temperature is unstable, because the battery has no electricity and a considerable part of lithium ion Already have a memory battery. This method can release a part of the memory battery. When winter comes, put it outside for a while, and then go to the house. 2. There is another way to remove the battery, leave it for about a week, and slowly consume the electricity, first use the machine to fully consume the electricity. Then charge it all again. It is estimated that your current charging time must be very short. After the charge is full, disconnect it and charge it again. Repeat a few times. It is absolutely effective. The principle of lithium battery repair method one: the metal surface of the 18650 lithium battery that has been used for a long time will be oxidized to a certain extent, resulting in poor contact between the mobile phone battery and the mobile phone, and the use time of the lithium battery becomes shorter. Erase the rusty material on the surface to make the battery contact with the phone better. The principle of lithium battery repair method two: low temperature can change the electrolyte inside the 18650 lithium battery, and promote the chemical reaction of the battery that has just been frozen. The use process of a lithium battery is actually a charge and discharge process. During this period, the negative and positive charges in the battery collide with each other. The reason why the battery is becoming less and less useful is because the kinetic energy inside the electron is relatively large at normal room temperature, so the battery is in an active state and leakage is relatively frequent. When a lithium battery is placed in a low-temperature environment, the microstructure of the lithium film on the surface of the lithium battery and the electrolyte, as well as their interface, will change significantly, resulting in temporary inactivity inside the battery and reduced leakage current. So after recharging, the standby time of the phone will increase. The principle of the third method of lithium battery repair: deep discharge of the mobile phone is to achieve a deeper recharge by depleting the internal electric energy, which requires some unconventional methods. Think of a way to connect the phone to a small 1.5V light bulb, and the power inside the 18650 lithium battery will be transferred to the light bulb until all is discharged. How to use 18650 lithium battery correctly. The use environment of 18650 lithium battery: the temperature is 0~40℃ and the relative humidity is not more than 75% in a clean, dry and ventilated environment. Avoid contact with corrosive substances and keep away from fire and heat sources. . Charging precautions: The product is strictly prohibited from charging from the discharge terminal, and must be charged from the charging socket with the matching special charger. When the charging indicator bar on the charger stops scrolling, please remove the charging plug in time to avoid overcharging the battery. The normal cycle of charging and discharging lithium batteries is about 500 to 800 times. The lithium batteries at the end of their life must be recycled and disposed of in accordance with local laws. Lithium batteries will not be overcharged when they are charged. They are protected by internal circuits. The most feared problem of lithium batteries is excessively high. Temperatures above 40 degrees will reduce the amount of power the lithium batteries can charge into. There is no special way to activate the 18650 lithium battery, the lithium battery will be naturally activated during normal use. If you insist on using the circulated first three 12-hour long charge activation methods, it will actually not be effective. Charge according to standard time and standard procedure. Don't charge randomly, overcharge for a long time. Some people advertise that lithium batteries need to be fully charged for 12 hours for the first time. However, this is not the case for lithium batteries, and this approach will affect the life of lithium batteries.
