Water came out of battery: AWT+IPV D2

[thomthom]

So this morning, vaping on my Aeolus with TC setting, all of sudden my D2 said No Battery. I didn't think it was anything and was going to take out the battery, put it to recharge on my Xtar VC2. But I found there was liquid dripping in between the battery's negative end, and the mod's connection tip. I took that AWT red skin 18650 out, and wiped the brown ish fluid out only to find the battery is actually soaking with even more of that stuff. About two third of the battery skin already turned into darker color, obviously the liquid came out of the battery from inside.

I checked carefully to ensure that the fluid didn't come from outside the mod, there was no trace down elsewhere of the case nor it has anything looking like the ejuice that I've been using recently.

Now I rethink, I shouldn't have clean the mod and battery before I took this picture, but I didn't think it's worth mention at all, until I found the battery actually soaking in battery fluid. The battery came in in a wholesale package directly from AWT like two months ago, which the company was kind enough to offer our little local vaping group. So I still have other few of their yellow and red battery, which I'm going to put in the same IPV D2, and test them. Shall I have any more update or finding, I'm here to share.

Yes, share, experience, I'm not here to comment on any brands or products or making complaints. JUST try to state the fact.

Thank yoy all, have a good one.

Welcome to ECF!

That battery "vented", and that can be a pretty serious situation. Not only is that liquid pretty nasty stuff healthwise but it indicates that the battery was either faulty or was used way beyond its rating. Or, perhaps, left in a very, very hot car. When a battery vents it can just ooze liquid out or it can burst open quite violently.

It appears that it's either the 35A/3000mAh or 40A/3000mAh AWT battery. These are probably 20A batteries, good up to about 60W or so. What was your wattage setting?

I don't want this to come off as criticism or harsh critique of what happened and the testing you plan to do but you're not only risking damaging your mod, but injuring yourself too. I highly recommend only using those batteries below 60W...50W is even better. If you were below that when they vented I recommended not using them at all, at any power level. Your health is much more important than free batteries.

If you might be a little curious, here's a bit of info about battery ratings...

There are no 18650 batteries with a genuine rating over 30A! | E-Cigarette Forum

Battery pulse ratings are useless! | E-Cigarette Forum

Hoping you find some great threads to dive into here at ECF!

Thank you so much for the warm welcome, and much information.

As I stated, it was in TC mode, 40J, 400F.
It's my indoor setting, no direct sunlight, no hot car storage. I mainly drip indoor, using RTA with my other mods while traveling.

Ahh, my bad. Missed that you mentioned it was in TC mode. Thanks for the joules setting as I don't know if some mods are limited by other settings, or not, when in TC mode. Does the D2 spend any time above your 40J setting in TC mode? In my opinion that battery should not have vented at 40J...which worries me. If that battery had an internal fault, perhaps others could too.

Looking forward to hearing about your experiences with the other AWT batteries you have. Work your way up slowly though.

The IPV D2 came in like 10 days ago, I have tested its VW function at around 45~50 watt, with other battery, AWT, Samsung, efest, etc. But I mainly play with its TC function. 35J to 40J, @370~410F, with different type of coils and atties.

The D2 has no real time, active temperature, output power, and wattage readings, only the resistance and battery indicator would jump while firing.

Thank you for the inputs and reminder, I'll keep in mind and try not to take too much risk testing

 

[thomthom]

*You can still see battery fluid stain on the negative end

Test been going on, latest result:

Samsung INR 25R (came from Nkon battery) - Vented!

I've been using this battery with mech mod with build as low as point 3 ohm and it was working fine, now, it vented after like half hour of use in this IPV D2, in TC mod with below setting:

35J, 375F, dual coils Ni200 build reading 0.086ohm

OMG!

Purple skin eFest 35A battery up for next test.

 

[Mooch]

I highly recommend stopping this testing. If you vented a 25R then you were drawing more than 30A from it. Sounds like the mod is just applying full power and pretty well staying there. I know TC cycles near a particular level but this sounds like more than that.

Send it back. Good luck getting p4u to understand your English. It can be hard with some Chinese companies

 

[crxess]

I suggest you return your mod or check closer on what you have going on.

Your settings are no where near exceeding Battery capability and the mod does have decent protection.

Negative is the TOP connection so wondering about the reported negative dripping on the connection. Tipped upside down?

I've run 45J/535F without any issues on Samsung 25R

Been steady 26J/415 for the last 2 days.

One battery vented right? That is not a case to where you would return the mod unless there was damage done to it. It is still working. Batteries vent. TC beats batteries up like I have never seen before. The load put on the cells when you first fire is really high, I am comparing this to my SX350. A weak battery wont hold up in TC IMO.

OP I think your mod is fine. Your battery had a failure, it happens sometimes. Keep eye out for any more problems but I think you will be ok.

Op is now claiming (2) Vented, AWT and Samsung.

I'm still wondering:
A) How no noticeable fail in Vape - sudden Hot Vape or something?
B) How they are Bottom(negative) Venting when the Vent is designed into the Positive cap?
c) How one gets a No Battery warning?

Output Current Min. 1A, Max. 25A

Thanks, and glad to hear yours is working fine.

I'm not making any conclusion, yet, did one more simple build as shown in picture below, running 35J, 385F with a purple eFest 35A battery, lets see how it'd go.

I'm doing this, mainly because I talked a few of my friends into buying this same device, I feel responsible to find out is this safe to use.

One more thing, FYI, both times the batteries found vented, the mod didn't get like unusually hot, just the power dropped and the device worked like it's out of battery. Then I checked them and found them dead.

I mean, TC device like this, should have been programmed to heat up the coil safely, it should never draw too much amperage from the battery even if I long hit for the first puff with the joule set high, does that make sense?

@Mooch Thank you for the heads up, I really appreciate it. I'll try my best to stay safe during the test.

@rhelton Totally agree with that, just can't imagine how many more ppl out there actually using 20A batteries (real rating) with their TC mods like me.

Batteries dont vent from the bottom, they are one piece construction with a opening at the top. The actual cell is flat and then rolled like a jelly roll and put into the case. Then they seal it at the top with the positive pad and crimp it. During a vent the electrolyte comes out the top and probably could have leaked down the cell under the wrapper. There may have been a warning and he did not see it im not sure. It sounds all kinda weird to me to be honest. I want to see under the wrappers and under the positive pad. I do not see any signs of a vent on that battery, it looks like juice got under the wrapper. OP make me a believer please.

 

[crxess]

Best of luck in solving this. Hoping it is simply tired batteries failed form use. Your build looks good and the unit seems to be working. We already have a lot of satisfied users, but there can always be that Monday/Bad day mod where something went wrong during assembly.
Hope if it is the Mod that you can exchange it and give the D2 another shot. when right it really is a nice little device.
Performance is on par with my SX mini M Class.

are you even aware of what can potentially happen?

 

[LouisLeBeau]

I agree, no wrapper melt. It takes only a second for a shorting or over amped battery to melt the shrink wrap and at LEAST leave holes in it.

The heat from a shorted battery will melt the shrink wrap before outgassing could produce any vapor or moisture. I can't see how liquid can be present AND the wrapper be 100% intact.

Does NOT look like a melt or venting event. Something else is going on here.

Fully agree, just can't figure this one out.
Cannot be the 510 leaking e-liquid - It is over the chip, not the (separated)battery compartment.
Battery sits Positive end Down in the Mod.
Liquid should not run uphill to the negative end.

Mysterious indeed.

I've had quite a few batteries vent (during testing) without the wrapper being affected. But, this is still a mystery, @crxess and @rhelton bring up some very good points!

 

[thomthom]

@crxess On the contrary, it didn't get hotter than usual, the mod just acted like out of battery, with no battery signal
@rhelton Now you said it, should I unwrap the battery try to trace the origin of leaking?

First idea came to my head, I should probably put the batteries back to charge, to make sure they're dead dead?

I really can't tell for now, where did the brown fluid come from, I mentioned the negative end, maybe because it's a flat metal surface, the fluid more noticeable there?

I can only be sure on two things:
1. there's some fluid between the cell and the battery skin
2. that fluid was on the device's negative connection plate, but not on the spring under that plate, because I suspect that the fluid came from the 510, so I checked very carefully my atty's 510, the device's spring load 510, and the battery compartment, all clean, except the negative pin, and the battery.
