Lithium ion battery

lithium battery  ICR21700 3.6 V 4.2Ah High Power Battery 21700 20700 Lithium Ion Battery 3.7v 
21700 is a Li-Ion (Lithium Ion) cylindrical cell that uses its dimensions as it's designation.
These cells have a nominal open circuit voltage of 3.7V per cell and a full charge voltage of 4.2V.
21700 cells have been used for some time in cars, electric bikes, vapes and numerous other battery pack applications.
However, they are increasingly finding there way into more and more diverse consumer devices such as high powered LED torches.
Some of the advantages of Li-Ion include a high energy density, low maintenance, low self discharge rates and depending on the cell a high maximum continuous discharge rate.
21700 Battery Cell has a dimension of 21mm diameter and 70mm in length. The cells are slightly larger than the 18650 and have a higher capacity.
These cells have the same nominal capacity of the batteries they were designed to replace, as they still came as 3.6 volts to 3.7 volts. Yet, they have a greater capacity of 4,000 mAh to 5,600 mAh.
