Introduction to 18650 battery performance

1. Purpose: Because of the large capacity per unit density, it is often used in most notebook batteries. In addition, it is also often used in high-end glare flashlights, portable power sources (mobile chargers), and so on. 2. Size: The numbers 18650 represent the appearance size: 18 refers to the battery diameter of 18.0mm and 650 refers to the battery height of 65.0mm. (Our general No. 5 battery [AA battery], size is 14500) 3. Type: 18650 batteries include lithium batteries and nickel-metal hydride batteries. Since nickel-metal hydride is rarely used today, we are currently talking about 18650 batteries, without special instructions. , Is a batch of 18650 lithium batteries. 4. Voltage and capacity specifications: Ni-MH battery voltage is 1.2V, common capacity is 4500MAH, lithium battery voltage is 3.6V-3.7, common capacity is 1500MAH-2600MAH, and the current maximum capacity is 3000MAH. The 18650 lithium battery has great advantages in terms of weight, volume, and capacity compared to the currently commonly used AA battery. For example, a 2400MAH 18650 battery, the voltage is calculated according to the standard 3.7V, and the power is 8880MWH. 18650 lithium batteries can be divided into many types. The 18650 lithium batteries sold on the market are also divided into multiple price points according to the difference in brand capacity, each for different consumer groups and markets. Different use environments correspond to different products. As consumers, they must consider all factors before purchasing. 18650 lithium battery has the characteristics of large capacity, long life, high safety performance, and because of its small size, light weight, and convenient use, it is deeply loved by consumers. As people continue to deepen the research on 18650 battery technology, the consistency and safety of the battery have reached a very high level. As the earliest lithium battery, the 18650 battery is also the most mature and stable battery pack in the world, and it still occupies the leading position. my country processes about several billion pieces of 18650 batteries each year, far exceeding batteries of other materials.
