　　How to judge the quality of 18650 lithium battery?

　　1. Use a multimeter to test the gear with the DC gear greater than the rated voltage of the battery. For example: test dry battery 9V, 1.5V with DC10V, DC2V gear test.

　　2. After selecting the gear according to the rated voltage of the lithium battery, connect the positive and negative poles of the battery with test leads. When the test voltage is greater than or equal to the rated voltage marked on the battery. The battery is fine. When the test voltage is 10% lower than the rated voltage, the battery can be used on electrical appliances with a small discharge depth.

　　3. It needs to be reminded that the voltage of rechargeable batteries is generally 15%-25% lower than that of similar batteries. For example, the voltage of battery #5 is 1.5V, while rechargeable batteries are generally only 1.2-1.3V. Therefore, the rated value marked on the battery should be carefully confirmed.

　　Now the 3.7V 18650 lithium batteries generally have a cycle life of about 500~1000 times, and the 3.2V 18650 generally have a lifespan of more than 2000 times. Of course, the premise is that the batteries produced by regular manufacturers are qualified. If they are defective or counterfeit batteries, the life span will be reduced. very short.
