Blend in with the crowd OR let everyone know you are not smoking a real cigarette. The choice is now yours with a simple "Tap." This battery gives you the ability to press the LED button on the end of the battery at any time to change from Amber(RED) or BLUE. This NEW “Amber/Blue Tap Switch” technology (patent pending) was developed by 7's.
7's Micro batteries use the best in Lithium-Ion technology for a longer life and a shorter charging time. Unlike other batteries, the 7's Micro gives you the performance to make it through the day on one charge for most smokers. These Micro batteries are to be used in conjunction with 7's Cartomizers. The life of a battery varies per user, just as smoking does. Expect one battery to last approximately 3-6 months, depending on use and number of batteries used. Each battery comes with a 90 day warranty.
