What is the 18650 lithium battery?best portable solar generator

　　1. Birth

　　In fact, 18650 is a standard battery model customized in order to save corresponding production costs for lithium ion batteries. It is specifically explained that Sony is the originator of lithium ion batteries.

　　Second, use

　　18650 battery life is generally 1,000 charging for recycling. Because the battery unit density is more capacity, the general purpose is as a laptop battery. And because of the high stability of the 18650 lithium battery, it is also widely used in major electronics fields, such as high -end strong light flashlights, portable power supply, wireless data transmission, electric heating clothes, shoes, portable instruments, portable lighting equipment, portable printer, portable printer , Industrial Instruments, Medical Instruments, etc.

　　3. Difference

　　18650 is only a size model of the battery. What it means is actually 18 mm in diameter and 65 mm long, and 0 means cylindrical battery. Generally, 18650 lithium batteries are more common in industry.

　　Fourth, general configuration

　　The general configuration of the 18650 lithium battery is as follows:

　　Single -nominal voltage is generally: 3.6V or 3.7V

　　The charging voltage is generally: 4.20V (cobaltate is 4.2V-4.3V)

　　The minimum discharge termination voltage is generally: 2.75V. Below this voltage can easily cause the battery capacity to be severely decreased or even scrapped

　　Maximum charging termination voltage: 4.20V
