18650 battery 2000mah.What does 18650 lithium battery refer to?

　　18650 is the originator of lithium batteries. It is a standard lithium battery model developed by the Japanese company Sony in order to save costs. The 18650 battery we often mention is actually a lithium battery named after the size of the battery. 18650 The 18 in it means that the diameter of the lithium battery is 18mm, 65 means the length value is 65mm, and 0 means it is a cylindrical battery. The most commonly used battery in household batteries is AA battery, and its model is 14500, which translates to It is a cylindrical battery with a diameter of 14mm and a length of 50mm; in simple terms, 18650 actually refers to the size model of the battery. According to the type of battery, the common 18650 battery is also divided into lithium-ion battery and lithium iron phosphate battery. Currently on the market The former is used more frequently;

　　What are the advantages of 18650 lithium battery?

　　The results show that the 18650 lithium-ion battery has the characteristics of high energy density, no memory, and long service life.

　　1. The capacity of 18650 lithium battery is very large. The capacity of 18650 lithium battery is between 1200ma-3600ma.

　　2. The longer the service period, the longer the cycle of using 18,650 lithium-ion batteries. If the normal cycle system is used more than 500 times, the rechargeable battery will be more than twice as long;

　　3.18650 rechargeable battery has no memory, and the battery does not necessarily discharge the remaining power before charging, making it more convenient to use;

　　4. Small internal resistance and small irreversible volume damage can greatly reduce the power consumption of the rechargeable battery itself and extend the battery life;

　　5. The 18650 lithium battery has a high safety factor and is not likely to cause explosions or environmental pollution. Test data shows that due to the separation of the positive and negative poles of the 18650 lithium battery, the probability of short-circuit failure drops to an optimal state in most cases. , The protection board of the 18650 lithium battery can modify the 18650 lithium battery. On the one hand, it can prevent the rechargeable battery from overcharging or power loss.

　　What is the use of 18650 lithium battery?

　　18650 lithium-ion products, 18650 lithium-ion batteries are more complete and stable worldwide, and their market share is also the leading technology of other lithium-ion products. In addition to pure electric vehicles and electric vehicle drives, 18650 rechargeable batteries are also widely used in notebook computers, Electronic products such as digital cameras and surveillance cameras;
