　　How to prevent car 18650 battery 3500mah failures and what precautions should be taken?

　　To prevent car 18650 battery 3500mah failures, you must first solve the problem of leakage and charger, and avoid excessive use of electricity when the engine is not running. In addition, be careful not to spill electrolyte on your hands or clothes; the electrolyte must not exceed the upper red line. Next, I will introduce the detailed content to you.

　　1. How to prevent car 18650 battery 3500mah failures

　　1. Charge the deeply depleted 18650 battery 3500mah with a small current outside the vehicle.

　　2. Test vehicle and 18650 battery 3500mah-related equipment to solve leakage and charger problems.

　　3. Frequently check the status of the connection between the wiring harness and the terminal post to keep it clean, dry and securely connected.

　　4. Develop good car usage habits and avoid excessive use of electricity when the engine is not running.

　　2. Precautions for car batteries

　　1. Shake the electrolyte well and add it to the 18650 battery 3500mah. Please wear gloves when operating and be careful not to spill electrolyte on your hands or clothes.

　　2. For batteries without marking lines, the electrolyte should be 10 to 15 mm higher than the plate; for batteries with two red lines, the electrolyte should not exceed the upper red line.

　　3. Some people think that the more electrolyte, the greater the power. This is a wrong idea. When the car is driving at high speed, the generator output voltage is greater than the 18650 battery 3500mah voltage and begins to charge the 18650 battery 3500mah. When charging, the volume of the electrolyte expands. If the electrolyte is too full, it will overflow from the small hole in the 18650 battery 3500mah cover. The electrolyte conducts electricity, and once it flows between the positive and negative poles of the 18650 battery 3500mah, it will form a self-discharge circuit. The car will not start and the 18650 battery 3500mah life will be shortened. In this case, wipe off the electrolyte with cotton or rinse with boiling water.

　　4. When adding electrolyte, do not let other objects fall into the 18650 battery 3500mah. If something accidentally falls in, do not use metal to fish it out. Use wooden sticks to pick out the impurities. If you use iron wire or copper wire to fish it out, metal molecules will enter the 18650 battery 3500mah under the corrosion of sulfuric acid and form self-discharge, damaging the 18650 battery 3500mah.

　　5. Regularly check whether the small holes on the 18650 battery 3500mah cover are ventilated. If the small holes are blocked, the gas generated cannot be discharged. When the electrolyte expands, it will burst the 18650 battery 3500mah shell, thus reducing the life of the 18650 battery 3500mah.

　　6. Check the liquid level of the electrolyte regularly and add electrolyte in time when the liquid level drops.

　　7. If the vehicle is left unused for a long time, the vehicle should be started every 25 days and run at medium speed for about 20 minutes. Otherwise, if the car is left for too long, it will be difficult to start.

　　8. When removing the 18650 battery 3500mah from the car, remove the negative pole first and then the positive pole, and do the opposite when installing. Be sure to unscrew the 18650 battery 3500mah cover when charging, and do not use an open flame close to the 18650 battery 3500mah port being charged, because the hydrogen gas generated in the 18650 battery 3500mah during charging can easily explode.

　　9. Do not casually replace the car's 18650 battery 3500mah with a larger capacity than the original 18650 battery 3500mah. Because the power generated by the car generator is fixed. If you replace the 18650 battery 3500mah with a larger capacity, the new 18650 battery 3500mah will be undercharged and the car will not start smoothly. Moreover, long-term 18650 battery 3500mah loss will shorten the life of the 18650 battery 3500mah.

　　10. When starting the car, each start time should not exceed 3 to 5 seconds, and the interval between restarts should not be less than 15 seconds.
