18650 lithium battery has high safety performance, no explosion, no burning; non-toxic, non-polluting, RoHS-certified; all kinds of safety performance in one go, cycle life can reach 1000 times. High temperature resistance, 100% discharge efficiency at 65 degrees. In order to prevent battery short circuit, the positive and negative poles of the 18650 lithium battery are separated. So the possibility of its short circuit has been reduced to the extreme. A protective plate can be added to prevent the battery from overcharging and over-discharging, which also extends the battery life. Due to the large capacity per unit density, most of them are used in laptop batteries. In addition, the stability of the 18650 is very good at work. It is widely used in various electronic fields: it is often used in high-end glare flashlights. Power supply, wireless data transmitter, electric heating clothing, shoes, portable instrumentation, portable lighting equipment, portable printers, industrial equipment, medical equipment, etc.
