anyone know a way of testing the voltage on the batteries?

[Josiah]

I was planning on walking into Ace and grabbing a bunch of metric nuts until I found the right one. Simple and effective. I'm not sure if you're UK or US but I'm just hazarding a guess that they didn't use Imperial on the ecig, so if you're US, a machine shop might not have the plug gage for that size.

I'll ask at work today if we have anything to measure pitch. I know we have some thread micrometers, so I can pick up the size, just not sure about pitch! As far as metal fabrication, I work at a machine shop. I'm an inspector, and have resources if anyone has any questions.

My first pen-style should be here within a few days, and I'll go ahead and get the thread measured when I get it. I might even reverse as much of it as I can and model it for fun. Having a nice set of drawings for them wouldn't hurt. I won't have a 901 for awhile, but when I get one I'll do the same to it. People can also email dead parts and I can do those, if they want.

I just purchased a set of tools to do just that, from Micromark, called a Thread Gauge, comes in metric or standard. I have a DSE901b, I'll measure the threads just as soon as the tool gets here.

sounds good josiah, but what do you mean when you say..

what can you do exactly?

[Josiah]

Reverse the threads. I'm sure someone that already has the parts can tell you the thread size and pitch, though.

I mocked up a more reliable battery set-up yesterday using a dead battery with the innards removed and the tube reduced to about 20mm in length.

Soldered a couple of wires to the 'screw' and connected it, via a small push button switch, to a Maplin 3 x AA battery holder - works like a charm.

Whilst in the workshop I also did some electrical & mechanical measurements - results as follows:

Output voltage (off load) of Normal, fully charged 'Classic' battery = 3.9 to 4volts.

Resistance of 'Classic' atomiser, around 4 ohms.

Off load Output voltage of 3 x AA (2500 mA/hr) ni-mh battery pack = 4.1 volts.

On load Voltage, (connected to Atomiser and with button pressed) = 3.9 volts.

Current pulled by atomiser = 1 amp.

I reckon this battery pack will last 3 or 4 days before needing to be re-charged - maybe longer.

There's not really enough male thread on the battery/atomiser connectors to get a real accurate measurement - but I'm pretty certain that it 10mm dia x 1mm pitch (in old money that's 0.393" dia x 0.0393 pitch or 25.4 tpi)

Because there is so little thread I pretty sure that a 3/8" UNF tap & die set will do the trick - thats 0.375" diam x 26 tpi.

Hope this info is of some help.............

1: Put battery in water for 30 minutes
2: Put battery out of water for 30 minutes
3: ????
4: PROFIT!!

[Tumbleweed4829]

omg! Why did I even try this???? On a few of my atomizers I get a fluctuating number (no clue what that means). I tried checking my battery and well it broke it by blowing into the led end (won't be checking any of my other batteries!)...so yeah not a good idea at all.

Is it just me? or is every one else totally clueless about the meaning of the last two posts.........

Lol, it gets like that around here sometimes Barry. Just let it go over your head if you can.

Thanks for the useful data you posted, I look forward to hearing more about your progress, photos too if you can get some. Super batteries seem to be a hot topic at the moment.

[BarryK]

Not much to see at the moment Kate, looks more like an IED than an e-cig at the moment - 3 batteries, an odd looking tube and a switch, all held together with rubber bands - people have been shot for carrying more innocent looking items than this.......

I will post some pictures later - maybe in the UK section.........

Cheers
