A common problem with e-Cigarettes that have automatic switches is a sticking or malfunctioning switch. These types of automatic switches are popular because they emulate a real cigarette and are turned on by the vacuum created when the user takes a draw. This is done by a hole in the middle of the atomizer and battery connectors that allow a vacuum to be created on the switch. This design though a sound concept, is flawed by the inevitable leakage of e-liquid into the battery compartment causing the switch to stick or short out.
To avoid any problems and increase the life of these types of e-cigarette batteries. I recommend that you do not drip directly on the atomizer and always use a cartridge all the while being careful not to over fill the carts. Also it is a good idea to always remove your atomizer from the battery every night or when not in use and allow it to drain.
If a battery is found to be staying on, disconnect the atomizer as soon as possible. You can try lightly tapping the battery LED end on a table or hard surface, or you can try blowing by mouth through the connector end. Do not use compressed air as this will damage the switch. Inspect the connector for any fluid and clean it with a Q-tip or tissue. Stand the battery (connector end down) on a paper towel and allow to drain over night.
