1) How long do you vape b4 putting your appliance down (approx mins/second) and how long are you finding yourself able to in between vaping 'sessions'(don't know what to call this)?
an hour. If I am off though I will vape for hours on end and one new XL lasted me from 830AM till 10ish pm and that's heavy vaping.
My battery is taking 1/2 as long to charge, lol!
2) How long should 1 new cartomizer last?
That depends on how much you vape and how long. I go through 2-4 a day depending if I'm off of work then its 3 or 4. If I'm working its 2.
Is that an improvement since you started vaping? (hope so!)
3) Approx how long (in inches) is the King battery w/o the cartomizer on it and how long is it w/ it on?
The size of a 100 analog
This is starting to make sense now....mine's slightly longer than 100 size but....
4) Same as 3 but for the XL batteries.
I'd say 1.5x the size of a 100 analog
not that long!
5) On manual batteries - Do you hear an internal click and bubble sort of sound when you pull? Is this normal and if so, what does the click sound mean?
Click comes from the battery and bubble might mean carto is over filled. A snap will come from the premmy carto also.
Thanks 
6) Also manuals - if you press the button during charging is the LED supposed to or not supposed to turn on?
Mine doesn't turn on.
Mine doesn't either.
7) Do V4L batteries have blue or other color (outside of red) LED's? If so, would you mind sharing a link to this info, if possible?
Yes they have blue green and orange that I know of. here is the proof.
YouTube - smilin/555 mix
Nice vid!
8) How many times within 24 hrs, are you/have you found the need to change batteries?
I have XL's so far with the new ones its one.
k.
9) In the one video about refilling cartos at the storefront, about halfway through, the person demonstrating how they are refilled, shows a black board of some sort, that stands the cartos upright. I couldn't make out what he said it was. Do you know what that thing is? Also, he's talking about refilling pre-filled cartos --- does this apply to blanks also and which do you get more use out of - the prefilled or the blank cartos?
10) How many different flavs do you vape on an average day? (just curious)
One-two a day.
It's my battery.
and, finally...
11) Do you find vaping makes you slightly a) relaxed b) hyper or c) no difference. (for long-term vapor users - how long did it take for you to get your energy level back and did you notice any changes in your appearance(ie - more color in your face, etc.)??????
A
Me=b - seriously b, lol!
