This is a guest post written by Morandir835, an e-cig enthusiast, admin on the Vapor4Life forum, and a regular on their ECF sub forum. Call it OCD, organized, or plain insane. I am a tester. I test everything that can be tested  on a personal vaporizer.  Apparently  I'm not the only person who keeps track of every charge, what ohm every carto  used is, how many minutes of use a battery supplies, and other variables. There seems to be  a whole group of folks who want to know everything their ecig  does, and are willing to share their findings.  I always find it fun to compare numbers from my own tests against what others have gotten. For one, looking at a few different sets of tests gives you a much larger  spectrum of observations to look at, and  secondly if any anomalies appear they're easier to find. So what does it take to join the testing ranks? Not much actually. The hardcore voltage testing does need  more effort, time, and hardware, but there are a few tests that anyone can do.  These can be performed using  no more than a pad, pen, stopwatch, and some way to mark the batts being used. If you have access to a multimeter and know at least some basics to using it you can easily check the ohms on every carto  before you use them. Just keep in mind your actual use time will vary in comparison to someone else's depending on your vaping habits. The end results of all this testing is the most important aspect. By knowing all the capabilities of your batteries you can find your sweet spot  in vaping, how long to really expect your batteries to last (both in use and over time), the list goes on and on. If you do happen  to be one of the "testing" types please contact me, as I would love to swap data at some point!
