Test 18650 battery appearance, A product 18650 electronic smoke battery exquisite appearance, the battery form film is smooth and wrinkled, and there are strict batterchants, and the specific battery data can be seen in the nozzle identification of the battery film. Measure the weight of the 18650 lithium-ion battery, the weight of the A product lithium ion battery is divided into the 1st product 18650 lithium ion battery pack weight, and the hand holds 18650 The fake battery is clearly sensing the battery is a casing. Truely fake battery weight comparative detection, 18650 lithium ion battery packs to the electronically weigh, then perform weight comparison; A product 18650 battery, the weight of the 18650 battery is generally 43g, and the weight of the fake 18650 battery is generally low It is 10G, and there are also 18650 fake batteries that are mixed with mud, and the mud 18650 battery weight is generally 30 g.
How to identify the 18650 lithium battery? 1. Use the multimeter direct current gear than the gear position detection of the battery rated voltage. For example, detecting dry batteries 9V, 1.
5V DC10V, DC2V file detection. 2. After selecting the gear position according to the rated voltage of the lithium ion battery, the battery is positive and negative.
When the detection voltage is greater than the rated voltage equal to the battery label. The battery is intact. When the detection voltage is less than 10% of the rated voltage, the battery can be used on the electric discharge depth.
For example: quartz clock, remote control, etc. When the detection voltage is lower than the rated value of 20%, the battery does not use value. 3, need to be reminded that the charging battery voltage is generally 15% -25% lower than the similar battery, and the 5 # battery voltage is 1.
5V, and the rechargeable battery is generally 1.2-1.3V, so the rated value of the battery labels should be carefully confirmed.
18650 lithium-ion battery life Theory is 1000 times in circulating charging. Since most of the unit density is large, most of them are used in laptop batteries, in addition to this, due to the stability performance of 18650 at work, widely used in major electronic categories: often used for high-grade glare flashlight, portable Power, wireless data transmitter, electric thermal warm clothing, shoes, portable instrumentation, portable lighting, portable printers, industrial instruments, medical instruments, etc.
