I got mine from LiquidXpress. I've seen one pic of the ones from LiteCig, and between these two, they are different. It would be nice if we could find examples of each vendor and have pics and stats (size, voltage) posted so we can compare.

Or find someone who has bought all the various 510 cartos to post a review of them all. ;)

I'm also having a problem with batteries, the atty acts like it's not getting full voltage, it hardly fires, so while I was trying different batteries, it all of a sudden sizzled like crazy. I took it apart and noticed I had put the battery in upside down, so I turned it around and again not firing well. So I tried another batt upside down and again sizzle, sizzle.

Is it OK to put the bat in positive first, the atty doesn't care, right? The bat is a little loose for some reason that way but it fires like crazy.

some more investigation says its the switch end thats the problem, if i take the switch out and tilt a paperclip in between the body of the precise and the (-) side of the bat it fires as it should.

You don't want to put the battery in backwards as, yes an atomizer may work in reverse, but you are now running the postive current through the body of the unit, which is a big short out hazard.

You shouldn't need a paper clip or anything to make it work.

What brand of protected 10440 are you using? unprotected ones are too short and the switch won't work, also when you put the battery in upside down like you did, the throw of the switch is also thrown off.

I test each and every unit personally before it goes out for both battery fit, switch throw and atomizer activation, so if you are having problems, i'd look to the battery first, atomizer second. Another thing i noticed on a blue protected 10440 i had, the blue plastic covering on the battery which also holds on the protective circuit, was way off center and the button wouldn't make proper contact with the bottom of the battery, so that is something to look at to.

Also, verify that the Rubber Oring is still in place at the bottom of the battery chamber and is pressed flat up against the ledge it rests upon.

Thanks for the response, I am using Protected Ultrafires (Blue ones) I got from madvapes, I got 4 and 1 of them shorted from the side of it, 1 of them is a little wide in places, but i got it to fit, and 2 of them fit good diameter wise, but lack in firing the Precise correctly. I have ordered Trustfires from DealExtreme but have not received them yet.

I just used the paperclip to determine if the switch side or the atty side was the problem and apparently it's the switch side. I know it's not the Precise, The problem is the batteries are not as precise as the Precise. I looked at the bottom of the battery and it doesn't appear that the switch is making full contact with the negative side, there seems to be a half circle mark but thats it. I assume the bottom of the battery is not flat, but is making contact.

The atty does fire, but acts like i put another resistor in series with it or something, "not much power" I hope when i get new batteries this will be resolved, in the mean time maybe I will try noalox as mentioned earlier.

BTW, The Precise is beautiful, a real work of Art, and again thanks for the help.

UPDATE - checked oring and it's ok, the bottom of the batt appears to be centered, so then I tried a little noalox on the switch contact and holy smoke I got all kinds of vapor - thank you to the poster who mentioned this, at least now I can enjoy my Precise while waiting for some decent batteries.

Do you by chance have a voltmeter to test the battery voltage and and to check the resistance of the atomizer? You may also want to check the voltage that is reaching the atomizer top post when the button is depressed. It should equal what you are getting for voltage when checking the battery out.

Atty resistance is 2.5 ohms, battery voltage = 3.79 vdc, voltage on the post is 3.79 vdc also, but it seems to build up to it, meter reads 3.5, 3.65, then 3.79 vdc, kind of pressing hard on the switch. With noalox on the switch, the voltage on the post jumps right to 3.79 vdc ( no hesitation at all). Maybe the bat is not flat and a little short also.

Redrhino - those are what I ordered from deal extreme and am waiting for, but maybe I should order from battery junction as shipping would be faster - Thanks for the link.

Thanks for confirming that. I knew I wasn't crazy! :thumbs:

Your atomizer's resistance is approximately where it should be. The battery voltage, though, fully charged should be approx. 4.2 volt fully charged. Either your battery isn't accepting a full charge any longer or it was just low on charge. It was good to verify that the voltage is the same with the switch depressed unloaded. As I believe you already mentioned, you have some new batteries on the way, so retest the voltage of those when you get them in.:)

You Welcome cfrazer.....Anytime.....As far as ordering from Them, They are a reputable Company...And i personally ordered from them in the past....And had no issues or complaints....Just a word of advice DO NOT have them ship you anything by FED EX GROUND....It takes for ever....That's about the only bad experience i had with them....But other than that no problems at all...And the price seems to be very Competitive....Good Luck:)

My wife has been moving through the batteries on the Precise. Today she discovered one of the four 10440 TrustFire Protected batteries will not fit in the Precise. Kind of a waste of money, but the battery is different. On the PCB end it has a strip or something that is sticking out, causing it to not fit.

Thanks for the info, the battery should have been fully charged as it wasn't off the charger long, so i'll check the other batteries. I have verified my charger is putting out 4.17 vdc

Have you tried the roll method? Lay a flat cloth on a hard surface, lay the battery down and while push down hard, roll it. It'll push some of those protection circuits and their protruding strips down flat.

I just did and it seemed to help quite a bit. The PCB and strip were sticking out a lot. I'll try it in the Precise when my wife gets home this evening.
