So, say I get the Precise 18650.. How long does the battery last? Any downside to the unit as far as design, battery life?
I'm ordering the 18650 precise soon myself....so I'm basing my experience off of owning a super 6 (the super T line before the precise came out)...
the build quality is phenominal...being that it's all mechanical there's really nothing to be able to break, and since it's all stainless it does have a lifetime warranty...if need be you can even wash the freaking thing out...I work heavy heavy construction and I've had my super6 run over by heavy machinery and dropped in mud all sorts of other horrors...and it keeps going....unless I were buying a juice feeder I wouldn't buy any other device (and when the super T VV box and integrated feeder comes out well all bets are off)..
the bottom button actually becomes really natural in feel quickly (do this take your eGo and rest the end of it on your pinky...fingers wrapped over it, index finger wrapped over the cone and thumb on the button pointing toward you...now kinda just squeeze your hand..you'll feel your index finger and thumb kinda pull the eGo down against your pinky... that's all it is just kinda flexing/squeezing your hand)
but the horns on either side of the button do help prevent pocket missfires..not saying it couldnt happen if you shove it in your pocket with a bunch of other stuff but I've never had it happen
as for battery life ...well that all depends on what atty you're using...the quality of the battery....and you're vape habits..
but I can help break it down from a math standpoint...
let's say you're using a 1.5Ω LR atty... and lets say you're using a 2900mAh redilast 18650 battery...
the LR atty at 3.7V has an amp draw of 2.47A (or 2470mA)
so 2470mA divided by 2900mA (of the battery) means a discharge rate of .85C
since that battery rating is 2900mAh we have to divide that hour by the same C rate
so that'd be 70 minutes (if you were holding the button down continuously) ...or 4235 seconds
so we break that down by how long you hold the button on average and how often on average you hit that button...
4235 seconds continuous is like 1411 (3 second long) button presses or 847 (5 second long) presses..
so how often are you hitting the button?
(that's like 11 hours solid of hitting the button twice a minute every minute for 3 seconds by the way or (7 hours with 5 second long button presses))
anyway those numbers would change with an atty of a different resistance (compare to like 7058 continuous seconds with a 2.5Ω atty)...
they'd also change with difference in batteries (and the only ones I'll use are AW or redilast)
and of course depending on how heavy you're hitting it
but 11 hours solid for a drag every 30 seconds doesn't seem too shabby to me and I'd call that pretty heavy usage
by the way also repeating this:
Precise 16340: 18.5mm x 74mm
Precise 18650: 20mm x 104mm
an eGo is 14mm in diameter... that's the size of a AA battery...
and as far as batteries go their number IS the size measurements of the cell
so a 16340 is 16mm x 34mm and an 18650 is 18mm x 65mm
so ceasar's claim about the precious.... well...lets just say that all aren't in agreement of his claim that they are the smallest
seems the reality is that the precise is thinner but longer than the precious (so which qualifies as smaller?)
