Our most popular range of e-cigarette batteries and the latest version in the V3 range. These are similar in style and size to a tobacco cigarette, with the V3i model providing an upgraded internal battery and switch, for increased efficiency and reliability when compared to the original V3 model.
Automatic batteries activate automatically when you inhale, much like a traditional cigarette. Just attach the cartomizer to your battery, and you're ready to go.
Manual batteries are a little different, although still simple to use. Screw the cartomizer onto the battery, and when you're ready to inhale, hold down the button on the battery. Release the button when you have finished inhaling.
