Coils burning out quickly

[chiliphil1]

Hey everyone, I am still sort of a newbie with vaping. I am using an Aspire vivi nova 3.5 clearo on a standard non VV ego battery. I wasn't having an issue before, I have had this tank about a month and used 2 coils in that time but here lately this thing is eating coils, first one burnt out in 5 days, and I just replaced another one at 2 days. When I say burnt out what I mean is that it has a bad burnt taste, it still produces albeit less than normal but the taste is horrid and when I remove the coil it is all black and nasty looking. I have not changed juice lately, I am using EC blend 7 leaf and ry4 which is 60/40 18mg..

Any help here would be greatly appreciated as this spending $2 every couple of days is going to add up quickly.

Could be a bad batch of heads, the QC on mass produced replacement heads is almost non existent.

What resistance heads do you use?
You can try soaking them in PGA then a gentle dry burn then rinse again, blow out and allow to dry.

Are you using the standard BDC (Bottom Dual Coil) heads or the newer BVC (Bottom Vertical Single Coil)? Are you priming the coil properly before applying power? Best Priming strategy is a drop on each juice inlet hole, then place a few drops down the center into the coil assembly, seal the tank up, take a couple of unpowered pulls on it (like 3-6 pulls depending on liquid viscosity), then gradually fire the coil up to full output (start with a couple 2 second fire, then couple 3 second fire, then a couple 4 second fire, etc)

Burnt taste is the result of poor wicking. When an unstaurated wick is heated the vapor production is small and the dry wick 'cooks' what ever juice that did not vape. Possible causes are:
Too much airflow causing less than optimum vacuum in the atty head chamber and a less than saturated wick. try taking a couple of dry puffs then vape.
Too hard and long draws (chain vaping). This does not allow the wick time to recover sufficient juice to re-saturate the wick.
Too high a voltage burning the juice before it has a chance to vaporize.

Dual coil tanks were the final straw that pushed me to a Kayfun. Happy "ever after" (so far, lol).

Have you been using the same resistance coils when you didnt get the burning and now? or did you got to a lower ohm?

Also you can try priming the wicks, by sucking for just a moment before and after you push the fire button.


Or did you switch from the BDC to the BVC? because they work a tiny bit differently. The BVC really needs time to suck up juice when you first install it.

Have you tried cleaning out the coils? I think the ry4 is a coil killer... just my experience. Not sure if anyone else has had that problem or not. There are certain flavors that will do damage to the coil after a while.

My recommendation, maybe clean your coil every 1 or 2 days with coil killing flavors.

why not trying another type of e-cig

Ok, lots of replies, thank you all for those. I will try to answer them all.

I am using genuine Aspire BDC heads in 1.8 ohm, I did not mix them up with BVC, they are BDC. This gives me another question though, I have a BDC tank, can I use a BVC in it?

These are the same resistance coils that I have been using since new

As far as priming, I didn't think to drip juice on the air inlets, but I do put 2 drops down the drip tip and take a couple of puffs before I fire the coil.

This problem is not when the coil is new but after some use.

I do tend to chain vape but have not had an issue until these last couple of coils and that is using 4 different types of clearos including this one.

I have NOT cleaned the coil, I didn't know that could be done, I tried that long ago with an EVOD and learned, or at least thought I did that getting them wet was a bad thing.. ok, checked and found how to clean them, so just soak in vodka, air dry, then dry burn?

Thank you again for all the tips, I will try to start priming better and try to draw a little before and after the coil fires.

The RY-4 I get is awsome from $3.87 Hangsen E-liquid for Electronic Cigarettes (30ml) - Ruyan 4 flavor / 24mg/ml nicotine at FastTech - Worldwide Free Shipping. That liquid does not eat my coils. I clean my coils every 3 days or so. I can on average get 2-4 weeks from 1 coil. That's if I don't get a dud/crappy one that can't be cleaned many times. 2-4 weeks for me is the norm though.

 

[FallenRawToast]

so just soak in vodka, air dry, then dry burn?

that works

I add a couple extra steps, which is overkill for some flavors.

I rinse/soak in hot water for a bit, shake off excess water, soak in vodka, let dry, dry burn, then rinse in hot water, shake off again, then vodka, then air dry again.

The reason I do this all again, is because when you dry burn sometimes you get a bunch of soot that needs to be cleaned off again.

The stronger proof the vodka or everclear you use the better. In a lot of states that means only 100 proof, but if you are in a state that you can get 180 proof that is even more effective.

You can use bvc coils in the Vivi Nova. Go to the Aspire site read up.there are 2 sizes of bvc coils. You want the ones NOT for Nautilus or Mini. You'll get better flavor with bvc's so might be able to lower your voltage or watts, saving battery power & not burning juice or gunking up.

Today was the first try at using a cleaned coil. I sat them in vodka for 2 days, rinsed with water, then let them sit to dry for 2 days. I put them on my mod and dry burned them, but I think this is where I messed up. I installed the coils back into my vivi nova and my wife's et clear and the burnt taste was horrible! I dripped mine for about and hour or so and it got better, now I can't tell a difference between this and a new one, so I guess that's a win but as far as my wife she couldn't do it and I had to put a new one in her's.

Should I dry burn these coils? That seemed to wreck the flavor for hours.

 

[Kenna]

Chiliphil1, you probably need to do it a couple of times, & rinse the soot out before using. You don't want to be inhaling soot.
Read the post right above from Fallentoast.

some juices just gunk up your coils. I've vapid plenty of juices and usually the darker/sweeter ones turn to a burnt taste and affect the draw. I highly recommend you recoil every week or dry burn, but dry burning only works for so long.

 

[chiliphil1]

Update. I cleaned my coils using the double method given earlier, haven't used one yet but I do think they look better after the clean, burn, clean method. I found that my issue was coming from my tank. The vivi nova that I was using somehow got bent, the air tube down the center was off a little bit which caused a gap, the gap made the juice literally flood the coil which in turn made it burn out quicker than normal. The bent tube also made me have a pretty good leak as well.

My local b&m is amazing, she swapped me out to a vivi nova glass tank which isn't bent so it should help with my issue, my local shop also got some of the BVC coils in stock so I picked up one of those as well, so far it's great, the BVC coil is far superior to the BDC in my opinion, the production and flavor are vastly different and to my taste much better. The one issue I am having is that with the BVC in this tank when ever it's low it will leak like crazy into the 510 connector.. I got some gurgling so I pulled the tank off and there was a small lake in my battery and when I held the tank up I could see it dripping out of the bottom, aggravating! Other than the leaking into the battery my vape experience is almost where I want it. I was able to get myself an mvp2 last week and that brought a huge improvement to the whole thing but I still have this leaking issue. For whatever reason it doesn't leak when it is full, only when it's about 3/4 empty it will start and will leak at a good rate until it's empty. I can take off the tank and clean out all the juice, blow through the tank to clear any that's still in there, put it on and get a gurgle on my first puff, pull the tank off again and it's just as bad as it was before I cleaned it.

I don't know if there is a fix for this leaking issue, but I am willing to try just about anything. I will also say these tanks leaked with the BDC as well at the same level, but I never could come up with anything to correct it.

I will also add that I am currently saving funds to get either an aspire nautilus or a kayfun clone which I hope will end the leaking issue but for now something has got to give, this is beyond annoying. Later I am going to get a real kayfun but right now $20 vs $100 is pretty substantial.

When I was using replaceable coils, I always ran two in rotation. Every other day or so, I switched them out, one soaking in alcohol, the other in use.

 

[Sgt.Rock]

A variable voltage battery will most likely fix your leaks assuming there's no mechanical issue with your tanks or the installation of the coil.

Crank up the volts on those BVC coils...I run mine at 4.2 and never have any issues...

 

[PaulieD]

I run my BDC coils (2.0 ohm) at 4.2 volts and don't have any problems.
BVC's just came in but I want to use my BDC's first, I have only 2 and the first BDC is on 5 days and going strong.

 

[Greg A Mays]

I had a friend whoi had the same issue and it just seems like he wasint using enough coild he doesn have ohm tester so he was just guessing then he took it to the shop we have here and they told him he needed to ad more wraps he did it and fixed it right up

 

[IMFire3605]

The leaking and gurgling was an issue with the Kanger tanks once down to below 1/3 a tank on the Protank 1 and 2. Surprisingly the elasticity between air and the liquid in the tank creates a vacuum suction that prevents liquid from just pouring in when above 1/3 of a tank, get below 1/3 a tank the elasticity of the air and vacuum can't hold the liquid back. Amazing the amount of physics involved in vaping -_-". So just have to keep the tank above 1/3 to keep from flooding and gurgling is all.
