What kind of battery is 18650 lithium battery?

Lithium batteries are divided into lithium batteries and lithium batteries. Some commonly used electronic products, such as digital equipment, small home appliances, and power tools, use lithium batteries. People usually call them lithium batteries. The difference between them and ordinary batteries is that they can be used in cycles of repeated charging and discharging, which is green and environmentally friendly. It reduces battery pollution and is a representative of modern high-performance batteries. Real lithium batteries are rarely used in daily electronic products due to their high risk. 18650 is actually a size standard. First of all, it is cylindrical, 0 represents cylindrical, 18 represents the diameter of the cylinder is 18mm, 65 represents the height of the cylinder is 65mm; so the 18650 lithium battery is a 18*65 size cylinder Shaped rechargeable lithium battery, it is an abbreviation for a battery cell, similar to 14500 lithium battery, 26650 lithium battery and AA or AAA battery. The rated voltage of the 18650 lithium battery is 3.7v. Depending on the energy ratio, the common capacity is 1500mAh~2600mAh, up to 3000mAh. In order to meet the needs of more equipment, the 18650 lithium battery pack appeared, which is based on the 18650 battery cells assembled in series and parallel to achieve a larger voltage and a longer discharge time.
