18650 lithium battery repair method

18650 lithium battery repair principle principle 18650 lithium battery repair method 1: the metal surface of the lithium battery will be oxidized to a certain degree for a long time, resulting in poor contact between the mobile phone battery and the mobile phone, the lithium battery has a shorter use time, and the eraser Or the use of other cleaning tools can wipe rusty materials on the surface, so as to better contact the battery and mobile phone. The second principle of 18650 lithium battery repair method: low temperature can change the electrolyte inside the lithium battery and promote the chemical reaction of the newly frozen battery. The use of lithium batteries is actually a process of charging and discharging. During this period, the negative and positive charges in the battery collide with each other. Batteries are becoming more and more useless, because at normal room temperature, the kinetic energy inside the electronics is greater, so the battery is active and leaks relatively frequently. The three principles of lithium battery repair methods: deep discharge the mobile phone, by exhausting the internal power source, to achieve a deeper level of charging, which requires the use of some unconventional methods. Think of a way to connect the phone to a small 1.5 volt light bulb, and then the internal charge of the lithium battery will be transferred to the light bulb until it is fully turned on. The mobile phone slowly runs out of power under low voltage. Under normal circumstances, when the mobile phone is connected, if the rated voltage is lower than 3.6 volts, the mobile phone will automatically shut down. After the battery is discharged, the mobile phone battery can be charged for a longer period of time. 18650 lithium battery 0V voltage repair method 1, you use all 18650 lithium batteries after use, the temperature, the battery temperature is unstable, the use time will be greatly shortened, because the battery has no electricity and quite a lot of lithium ions have power in this way You can make the memory electric release part of winter, outside, and then to the house. 2. There is another way. Remove the battery and leave it for about a week. The power will be consumed slowly, and it will be completely consumed after using the machine. Then charge it. It is estimated that your current charging time must be very short. If it is full, disconnect it and then charge it again. Repeat several times. It is absolutely effective. 3. Use a clean eraser or other cleaning tools to gently wipe the metal contacts on the lithium battery and the mobile phone, which is conducive to the charging state and long-lasting power supply. 4. Fully discharge the almost scrapped 18650 lithium battery, then charge and activate the battery. Method: Deeply discharge the mobile phone to achieve a deeper charge by exhausting the internal power. This requires some unconventional methods. Use a specific device to connect the phone to a small low-voltage light bulb, and the energy inside the battery will be transferred to the light bulb until it is fully turned on. Advantages of 18650 lithium battery 1. Large capacity. The capacity of 18650 lithium battery is generally between 1200mah~3600mah, while the general battery capacity is only about 800mah. If combined into a 18650 lithium battery pack, the 18650 lithium battery pack can easily exceed 5000mah. of. 2. Long service life: The 18650 lithium battery has a long service life. The cycle life in normal use is more than 500 times that of ordinary batteries and more than twice that of ordinary batteries. 3. High safety performance, 18650 lithium battery, no explosion, no combustion; non-toxic, no pollution, RoHS trademark certification; various safety performance, more than 500 cycles; high temperature resistance, 65 degrees power efficiency as high as 100%. In order to prevent short circuits, the positive and negative electrodes of the 18650 lithium battery are separated. Therefore, the possibility of its short circuit has been reduced to the limit. You can add a protective panel to prevent the battery from being overcharged, which can extend the life of the battery. 4. High voltage: The voltage of 18650 lithium battery is generally 3.6v, 3.8v, 4.2v, which is much higher than the 1.2v voltage of nickel-hydrogen nickel-cadmium battery. 5. There is no memory effect, and the remaining power will not be emptied before charging, so it is convenient to use. 6. The internal resistance is small. The resistance of polymer batteries is smaller than that of liquid batteries. The internal resistance of domestic polymer batteries can even be less than 35m, which greatly reduces battery power consumption and prolongs the standby time of mobile phones, which can reach international standards. The polymer lithium battery supports large discharge currents and is ideal for remote control models, and is the most promising alternative to nickel metal hydride batteries. 7. It can be connected in series or in parallel to synthesize 18650 lithium batteries.
