I have two 18650 batteries imren brand one purple 40amp and one green 38? amp. My question is I put my batteries in this mod and I didn't screw in the tank coil all the way down so it ground with the tank and the spring pin was also set incorrectly, so when I screwed this thing in and sat it down on my desk it got really hot really fast. I pulled out my green battery before anything really bad happened. The plastic coating on the bottom of the battery melted a bit. I put my purple battery in and adjusted the bottom spring and it shorted again, the purple battery pos and neg sides where to hot to touch but no melting occurred. My question is, is it safe to still use these batteries? I didn't ruin them did I?
Battery getting hot hot hot.

With a melted wrapper? Hell no.
Before you even think about reusing either of those batteries the first thing you need to do is check their voltage on a meter. If they were in there on a dead short long enough that it dropped the battery voltage below 1.5 volts I would just kiss them both goodbye. Cooking a battery by dead shorting means you have no idea if you damaged the internal structure of the battery, but a very low voltage reading after a dead short means you are at risk for having done that.

I checked both batteries and neither of them dropped below 4 volts, they were not in there for long, less then 10 seconds.
After a dead short, no one on here will tell you to go ahead and use them. Though, some of us would still use them if the tested okay and the damaged wrapper was replaced.
Listen to Old English & the Sheep, they're steering you right on this one.
If you want to see what the process is like, here's a tutorial that came up again recently after a guy ended up having to toss his battery onto the front lawn when he ignored wrap damage:

And the thread:

If it's beyond you, you can have someone locally do it... if the battery tests out, it would be a reasonable decision to rewrap and use it. But it would not be reasonable with a damaged wrap.

You absolutely must rewrap those batteries if you intend to use them again and make sure you get the sleeves that wrap around to cover a little of the flat bottom neg end of the battery as well. I do not have experience with the batteries you describe but know that until the VTCs came on the market many of the top batteries, such as CGR18650CH, had wrappers that covered the sides and wrapped around a little of the top of the battery but not the bottom. The problem with this is that with some mech mods they would auto fire as the neg pin housing of the mod in essence relied on the batter wrapper to cover the bottom edges and hold the battery off of the firing pin. Without that extra bit of wrapper the batter the mod would fire as soon as the pos end of the mod was connected.
I wouldn't use them, not after a short. You have no idea if there was any type of damage internal to the battery. Especially if they get hot enough to melt things.
Send 'em to the battery recycle place and get new ones.

P.S.- stop buying imren batteries when there are better and cheaper options out there...you can still find VTC3's pretty easily, not to mention samsung 25r, LG HE2's and even yellow MXJO are better than imren (but not by much on that lase one lol) and when these batts can ALL be found for less than 8 dollars, don't be cheap on safety
Maybe it is just because I have about 80 batts at the moment but IF one EVER vents...it is absolutely the LAST time it is ever used, I don't recylce mine as I should but I do put them in a plastic bagey and make them dissapear forever lol
Oh well, trash in my book, what are you using that is shorting them anyways??? other than the atlantis (which I didn't know at the time is a BAD idea with a hybrid connection lol) I have NEVER shorted a battery in a mod (now outside of a mod and testing how far I can push it is another story hehehehe)
To start with those battery's are way over spec's ratings and now you took about 3/4 of there cycle life out of them, melted wrapper is not worth the trouble it can cause to keep using.
My suggestion buy better battery's : Samsung 25R Rechargeable High Drain 18650 | IMRBatteries
Here's something you can stand on your desk and not have to worry about auto firing ;Eleaf iStick 50W Battery - Eciggity

Im interested in what mod you have..... need to put that one on my dont buy list...
Right??? I feel like that list gets bigger and bigger for me everyday lol
OMG! And it looks like you have enough empty cases to get you through, what, the next two weeks?

Lol, every empty case has a batt that it is home to as well, some are just at work and this is why I never understand why people won't just fork out 8 dollars a batt for good ones...although admittedly I only pay about 4 dollars a batt
Is this a dual 18650 mod? using both batts at once? You need to just get pairs of the same batteries and marry them.. In addition idk where you got your amp rating but there is no such thing as a 40 or a 38 amp battery as far as I know..
Nah-uh!!!! Efest just "designed" another "sony killer" 18650 38amp batt!!!! lol, I wonder what crap they are rewrapping on this one
