18650 Li-ion battery is a lithium-ion rechargeable battery and used in high drain application due to its superior capacity and discharge rate. The first 4 digits of 18650 indicate its dimension, i.e. 18mmx65mm, and the last 5th digit indicates its shape, i.e. cylindrical. Li-ion batteries can usually boast a 300-500 charge cycle.
