  (1) What is the quality test of 3C lithium-ion battery? 3C lithium-ion battery refers to mobile phone battery, notebook battery, mobile power supply and other consumer batteries. The use characteristics of 3C products determine the performance and quality requirements of 3C lithium ion batteries. Therefore, it is necessary to test 3C lithium ion battery. The difficulty of 3C lithium-ion battery testing is that the current is too high. The traditional probe module cannot meet the required current, so it is generally not used. Qizhitong elastic sheet micro needle module can withstand the maximum 50A current of 3C lithium ion battery through over-current transmission. It has good connection function and improves the test yield of 3C lithium ion battery

  (2) 3C products are widely used in lightweight, portable, high-performance, long life and other fields. New requirements are put forward for 3C lithium-ion battery, which requires high specific capacity, high safety and small size. It also puts forward higher requirements for battery manufacturing and packaging. The following methods should be used to detect the quality of 3C lithium-ion battery: 1. Check the appearance of 3C lithium-ion battery, investigate whether the appearance of the lithium-ion battery is damaged or deformed, and check the integrity and process accuracy of 3C lithium-ion battery; 2. Check the hardness of 3C lithium ion battery. Hold the lithium ion battery gently with your hand. Medium hardness

  (3) Check the weight of 3C lithium ion battery, remove the lithium ion battery package, and weigh the lithium ion battery. If there is a sense of weight, it means that the 3C lithium-ion battery uses high-quality batteries

  (4) Test the internal resistance and maximum current of 3C lithium ion battery. Select a 20 series multimeter and use two electrodes to short-circuit the lithium ion battery. At present, it is 10 or higher and can be maintained for a period of time. Relatively stable, low internal resistance, and high discharge current, indicating that the quality of 3C lithium ion battery is very good

  (5) 3C lithium-ion battery runs with electricity and discharges continuously for 10 minutes. The two poles of the lithium-ion battery do not generate heat, indicating that the 3C lithium-ion battery protection plate is of high quality and the battery quality is good. In the test of 3C lithium-ion battery, the service life of the cartridge microporous module is very high, with an average of more than 20W. If the operation, environment and maintenance are good, the service life can reach 50W. In the field of small spacing, the elastic sheet microporous module has strong adaptability and can be taken as 0.15 mm~0.4 mm. After the shrapnel is plated hard, the needle and pin are not easy to break during the test, and they are not easy to break for a long time. The micro needle module of Qizhitong grenade is processed by special technology using laser equipment. The integrated design makes the current conduct in the same data body, with constant resistance, almost no current attenuation, and very stable. While improving the 3C lithium-ion battery test power supply, it will not damage the lithium-ion battery connector, and the test yield is up to 99.8%! It plays an important role in the test of 3C lithium-ion battery
