Draw or air flow can affected by several factors with Auto
batteries most of which fall on the shoulders of the end user. Understanding how an Auto battery works and what affects draw or airflow/vapor while inhaling is key.
Auto
batteries require what is known as a "Primer Puff" a short inhale which triggers the activation switch allowing the heating element or atomizer to receive power from the battery. Once the unit is activated the user can then take a normal draw. This is the equivalent of pressing the button on a manual battery.
Draw or airflow is dictated by several intake holes on your battery, the notches on the base rim of your cartomizers, along with stepped grove on the cartomizer post.
There are 4 small holes located under the battery threads, these holes feed directly into the channel around the battery post. If your batteries are dirty and have a build up of residue these holes can become clogged. To unclog these holes you can give your battery connection a thorough cleaning or simply insert a sewing needle into them.
To enhance air flow there are 4 notches located on the outer rim of the cartomizer base. The notches work in conjunction with the air intake holes and to ensure air flow when the cartomizer is in place. When the cartomizer is properly attached to the battery there should be a hair line gap between the outer rim of the battery connector and the out rim of the cartomizer.
Many new users make the mistake of over-tightening their cartomizers onto the battery and screwing them all the way down impeding airflow. When this occurs they also inadvertently push the battery post down, the combination results in less airflow. This also can occur by over tightening the batteries when installing them onto a recharger.
To readjust your post and ensure proper airflow see the Sticky above and follow the directions on the video. Avoid over tightening your cartomizers on to the battery and when using your recharger. You only need to tighten the cartomizer or battery to make a proper connection.
