Samsung INR18650-25R (button top) was first released in early 2015 as a replacement of the 25R (blue). The cell has the same performance of 2500mA and a continuous discharge of 20A but has an increased cycle life. The high discharge rate and medium capacity of this cell makes it a first choice for industrial applications as well as home users that are looking for high discharge cells. This cell has become a favourite with vape users in recent years because of it's high current abilities.
