At present, the general cycle life of 3.7V 18650 lithium battery can reach about 500 to 1000 times, and the general life of 3.2V 18650 battery can reach more than 2000 times. Of course, the premise is that the qualified batteries produced by regular manufacturers will have a short life if they are defective or counterfeit batteries. 18650 The service life of lithium batteries is only two to three years.
