Can anyone tell me the length differences between the auto DAV batteries? I've searched the forums and blogs and the closest I came to was the blog E-Cigarette Battery Lengths. However, it doesn't include the DAVs. I even called customer service and they said they didn't have the exact lengths but they ranged from 4 to 5 inches. I was pretty disappointed in that answer.
Can anyone help? I apologize if this was already answered somewhere but I spent an hour searching and could not find the answer to what I thought was a simple question.
