The battery is generally the largest component of an electronic cigarette. Most electronic cigarettes employ a lithium-ion rechargeable battery to power the heating element. The battery component of an electronic cigarette is essentially the brains of the device. It is more than just a power storage device – it contains a microcomputer “smart chip,” operating mode sensor, indicator “ash” light, and the lithium ion battery cell, all concealed within a ‘cigarette’ looking aluminium shell. In basic terms, when you inhale, the operating mode sensor triggers the microcomputer “smart chip” to turn on, which then tells the lithium ion battery to begin releasing power/charge to the atomizer. The atomizer then heats up, thus vaporizing the nicotine solution found within the cartridge/filter. All this occurs while the indicator “ash” light glows red, showing the electronic cigarette is currently being inhaled.
Battery life varies depending on the battery type and size, frequency of use, and operating environment. You’ll know when it is time to place the battery on the charger when the indicator “ash” light dims considerably, inhaling becomes more difficult, or when the amount of smoke-like vapor diminishes on a new or fairly new cartridge/filter. Many different battery charger types are available, such as wall outlet, car, and USB chargers.
Batteries are available in 2 styles: Manual & Automatic.
Automatic batteries, sense when the user takes a draw from the cigarette and automatically activates the atomizer. The auto style monitors the length of the draw and shuts the atomizer off automatically after a certain amount of time (about 10 seconds).
Manual Batteries have a small activation switch that you press to manually activate the atomizer and will keep the atomizer on for as long as the switch is activated. Manual batteries are for the smoker who wants a really long draw and complete control over the atomizer. Batteries last 2-6 hours per charge and have a lifespan of 1-2 years depending on how they are used.
