"The emperor is naked !!!! "

[wizardofozone]

I feel like the boy in the story ' the emperor's new clothes' 'bout now but I must do the same truthful cry out as he did .... " A full day or 2 of battery life " ? .... Now I am retired so I've taken all of my free time into consideration but after a full year and several days of vaping a 3 battery 220 Watt God 180S, 2 double battery 100 watt Eleaf Isticks, a two battery Snow Wolf 200 watter, and the new 3 battery Reuleaux 200 with 6 new 18650s' I'm waiting to arrive, I think I can say with authority that either everyone else is lying, Or I'm the only one telling the truth, .... Or .... I have such a serious vaping problem on an hour by hour basis as to be a terminal vaping addict with no hope .... It just has to be one of these things because in every case, with any of the units above, with meticulosly maintained battery charging care .... 5 hours max is all I've ever been able to get as a life span with any of the above units and with so many different brands of 18650's it matters not which ones you might favor .... I only get 5 hours max from any of them .... What's up with that ?

I have been trying to carefully note the 'pro' utube reviews where the reviewer make an especially heartfelt rant about his outstanding full 24 to nearly 48 hour battery life times, then praising the unit itself rather than the batteries or even himself for having such control to moderately vape .... The last rave about battery life is on a Roeuleux review.

The least number of 'pulls' I probably do in any one hour of a day is probably 4 ..... is this some champion amount ? Anyone else actually get way more time and is a retiree ?

It does very much depend on usage! I can finagle 8 hours of life out of a fully charged LG HG2 battery (running at 1.6A, 4.8W, on a Kanger T3s in an eVic VTC Mini). But under "free time" usage (the thing lives in my mouth), it's closer to six hours.

My old 1,300 pen style, supposedly good for "13 hours" were really good for more like 2 hours. Tops.

I figure it's still worlds better than sucking down 2.5 packs per day!

What are you vaping on, and how many watts? Chain vaping?

somebody vaping 30ml a day will use up 3 times more batteries than somebody vaping 10ml per day.

[QUOTE="CosmicGopher"

I discarded my God 180s several months ago but I'm vaping at 65 Watts with factory sub ohm coils on 3 Herakles clearos and the new Herakles plus . If chain vaping is faster than 3 minutes per 'pull' .... than no, I'm not chain vaping .... My units are 2 istick 100 watters, a Snowwolf 200 watter, and im waiting on a 3 battery Reuleaux 200 to arrive.

Five hours? Kudos to you. I am between one to two hours max no matter the device or cell (typically the HG2 on box mods). Chain vaping at 80W-100W with builds that hover between 0.1 and 0.15 ohms.

wow Sig ! You make me feel way less crazy !!! (LOL!)

Time is a terrible marker to try to gauge vape usage or life by, what should really be the marker is amount of juice vaped IMO as this will more accurately translate from person to person regardless of vaping style or how many days go by, the amount of juice vaped off one battery charge should be much better than stating "this mod and battery combination lasts me four days" when the reality is that person may only vape 3ml per day and 12ml total over four days while a different person with the same device may vape 12ml in 8 hours or less with the same battery charge.

I don't really chain vape any more, but I'm able to suck through a full 15ml of juice on my Lethal box(triple parallel 18650 unregulated) at 0.12 ohms before I need to change the batteries, I haven't had a day in a long time that I consumed more than 15ml and it's one of the only devices with which I am comfortable leaving the house for the entire day with no extra batteries.

This is an excellent logical post Froth .... My mind is inclined now to agree about ml amount in a day rather than batteries or Mod used .... I was calculating as I read the last couple of posts that refilling my 3 3.5 Herakles tanks and my 5 ml Starre Freemax is all I do all day .... I'm waaay over 30 mls a day ... waaaay over ...

Take into consideration how many grams worth of coil(s) one has to heat up every time one wants to vaporize a couple drops worth of eliquids.

ETA: A made up example not based on any actual experience:
If you coil up a wire coathanger and feed it with an 18650, you could probably drain the battery before the hanger got hot enough to vaporize any liquids.

I get 14-16 hrs out of a 2000mAh CoolFire4 -- because I vape at 9w, using a 1.7Ω coil. It's all in how you use it -- if you're trying to use enough wattage to light your house, it's gonna run thru some batteries.

[edyle]

when you check the numbers, a 2000mAh cell only gives a FEW MINUTES of actual vape time.

 

[YoursTruli]

high watts/low ohms/high juice consumption=short battery life
lower watts/higher ohms/lower juice consumption=longer battery life

I vape at 10 watts/1.0 ohms/4-6 mls a day=15-20 hours of (single 18650) battery life and I feel like I vape a lot.

I know you do not feel like you are going though a lot of juice per day so I guess it is a matter of perspective, to me (also retired home all day) "waaay over 30 mls a day" is insanely high, but, to each their own vaping style

I retired 1 year ago and have way 2 much time to vape and watch vaping videos--hahahahahahaahahahahahah-------But these batteries don't

really last that long if you are busy drawing on it constantly..........just sayin............had good luck with my Eleaf istck 50 watt....

I don"t usually vape over 20 watts most generally.........

 

[AndriaD]

And yet it lasts me all day long and never even goes into the yellow. (ETA: and I vape about 4.5ml per day)

Ok, Everyone has convinced me that battery usage is as personal an experience as religious beliefs .... I'm only left then with the question about how so many utube 'pros', reviewing so many free units, who usually have only sub ohm clearos attached, and in a place where 24 hour vaping is no problem, and who usually only lung inhale as I also do ... dare suggest they are getting 24 to 48 hours from 2 or 3 18650 batteries ..... (lol!) Thanks everyone for the truth ! ...... I'm a terminal vaper at I'm guessing 50 mls every 24 hours !

 

[Hans Wermhat]

With a Kayfun at around 1.5 ohms, I get 10 - 12 hours on my 100W iStick with LG Brownies. On my iPV4 with VTC4's and the velocity @ .5 ohms (but huge 14 wrap N80 dual coils) @ 80W I can get 5 hours. I never go more than 5 minutes without a puff and it's usually more like 2 - 3 puffs per minute on the KF and 1 puff per 2 minutes on the RDA. I am a SERIOUS chain vaper.

 

[Jorge22]

I get about a day vaping at 6.5 w (cartos) and 11 w (BVC). You must understand it all depends on the way you vape. The higher the wattage, the lower the battery life.

btw; 50ml a day is a lot of stuff to be going though your lungs. you go through a litre in less than a month


Now:
there is a relationship between battery capacity (mAh) and milliliters of liquid vaporized.
Fluids - Latent Heat of Evaporation

for specific latent heat of vaporization of eliquid I am going to use: 1,000 kJ/kg
which works out to 1kJ/g = 1kJ/ml = 1000 Wattseconds/ml = 1000/3600 Watthours/ml
= approx 0.3 Watthours per ml.

a 2000mAh cell contains about 8 Watthours of energy
so in theory 1 cell has enough energy to vaporize some 20 ml of liquid.

factor in efficiency (alot of heat is lost) a more realistic figure is about 5ml.

1 2000mAh battery will vape about 5ml.

In your case at 50ml per day you can expect to use some 10 batteries in a day.

Yea Jorge that's becoming crystal clear and makes me glad i'm investing in 12 more 18650s over the next 2 weeks ..... All of this makes me curious to exactly measure how much liquid I'm going through .... Going to do that starting tomorrow.
