The Red EGO battery can only be described like Snow White’s lips; red as a rose or brighter than a fresh picked strawberry. While vaping on this radiant scarlet colored battery you can’t help but feel a little risqué. Our Premium EGO battery lasts well over 800 puffs on just one charge; that's four times the battery life of your traditional Ecigarette. Our Premium EGO batteries are exclusively designed to fit our cartomizers, the first of any EGO in the industry to be compatible with cartomizers! The EGO batteries are .5" in diameter, 3.5" long without a cartomizer attached, and slightly heavier than your traditional Ecigarette. All of our EGO batteries have a newly developed rubberized matte finish, making them easy to grip, smooth, and comfortable in your hand.
