The battery is designed to optimize the balance between usage time and weight.

The battery is made of lithium ion, similar to batteries you would use for certain cameras or watches.

You’ll know that it is time to recharge it when the light starts blinking.  Other signs that the battery is running down would be if you notice that inhaling becomes more difficult, or the amount of smoke diminishes on a new or fairly new cartridge.

Some of our customers like to have extra batteries so they can keep one at home, work, car, etc. Others like to always have one available. When one is charging you can use the other. Either way, it's good to have an extra one or two.

Cigarette Dimensions:

Length (Cartridge+Battery) : 98 mm (3.9 inches)
Weight (Cartridge+Battery) : 14 g (0.49 oz.)

(Note: Please don't screw the battery in too tight; you shouldn't have to force it. If you twist too hard, it can damage the contact point in the charger and prevent charging from taking place, if this happens, please let us know and we will replace it for you free of charge)
