Hi, the other day I bought an atomizer and my friend rebuilt it for me. I dropped my liquid on the wick and put a freshly charged battery in my k100 and when I pressed on the firing button for a second, the battery and mod got REALLY hot so I took the battery out and let it cool down. About 20 minutes later, I took another freshly charged battery and the exact same thing happened again. Now I'm wondering if these batteries are still safe to use because I'm getting mixed answers on how I should throw the batteries away and some vape shops I've called and asked said they're still safe to use. What do you guys think?
Are my batteries still safe to use? What do you guys think?

I'd say if they look ok you should be good, but I'm far from an expert.
It sounds like you had a short in your atty/mod....

Well, we need more to go on. Like what batteries are they - manufacturer and version. And did you test their voltage with a meter after the incident? Any physical signs of the batteries having been stressed - like bulging at the negative terminal now?
Yes, there is definitely a short somewhere. Clean your contacts and make sure your build isn't touching the walls of the RDA. Please check your battery as well to see if there is any black residue on the positive and negative contacts.
Your batteries should be okay, however, the overheating may have done unseen internal damage to your batteries. Exactly how hot did they get? Were you still able to hold your mod in hand? Or did it get too hot to even hold?
For peace of mind, you may just want to be safe and dispose of them.
Baditude, our resident battery safety expert, is by far the most knowledgeable person I have ever seen on stuff like this and I assume he should be by soon.

I would not use those batteries in a mech. mod to avoid any risk. They might be okay to be used in a regulated mod after inspection (no visual signs of trauma) though.
I suggest you get at least one regulated mod that can read the coil resistance so you can make sure the build has no shorts before putting on the mechanical mod.

Yep, an ohm meter will do. I guess I am a bit inclined towards regulated devices given the risk of mechanical mods for the inexperienced 
A ohm reader will also have a wider range then most regulated mods as far as reading ohms. My MVP will not read anything under .5 ohms.
On the topic of the mater we do need to know what kind of batteries you are using and the ohms of the atomizer. It is possible that the atty is dissipating heat into the body of the mech mod pretty fast. My copper nemesis gets warm after a few pulls at .25 ohms, but I would not say it gets hot. If you have no idea what is going on under the hood of your atty I would really suggest spending time learning about the art of rebuilding attys, Ohms Law, and battery saftey. It is really apparent that your friend does not as he should have never handed you an untested coil build.

Do you have an ohm meter, or a multimeter? I never put any topper on a mod without first checking the topper for shorts.
All true about an ohm reader being cheaper but a multimeter offers several other features useful for vapers, including voltage measurement of batteries, measuring internal resistance of batteries (best way to check their "age"), identifying a short point using continuity and so on... My two cents.
Personally think that the biggest advantage on an ohm reader is the fact that it hold an RDA just right for building coils!

I think you didn't do enough research before your bought a mechanical mod and started using an RBA. This is an "advanced setup" and not well-suited for novices who have not done their research and educated themselves.
You are either using the wrong batteries or you have a short somewhere in your setup. You didn't say specifically what batteries you are using (make, model number, amp limit) nor what ohm coil your friend made for your atty. This is critical information that you must know. Not all batteries are created equal, nor do they all have the same specifications for different applications (particularly when it comes to amp limits).
Anything can cause a short and cause the mod or battery to get hot. A bad 510 connector or insulator, faulty or dirty fire switch, dirty battery connections, loose post screws in the atomizer, a hot spot in the coil. A hot battery or mod is not normal and a sign of danger.
Information Resources for Your First RBA <---- read this, understand it, practice it.
You must have your own meter to measure your coils. You should also have a voltage meter to insure you don't over-discharge your batteries in a mechanical mod. A digital multimeter or omntester will do both. Never fire a coil on a mechanical mod if you don't already know the resistance of the coil. Coil resistance can change over time that you wouldn't be aware of (ie. a loose screw on the atty post holding the wire), so always periodically check the resistance. A coil changing resistance of a couple tenths of an ohm could be critical.

Batteries should never feel REALLY HOT. They can suffer unseen internal damage even if the external appearance looks fine. Not worth the risk if you ask me. My advice is to get some new batteries, and make sure they are the right kind and can easily handle the resistance of your build.

Appreciate the input guys. The batteries I have are Sony 30 amp 18650 batteries. The batteries themselves do not look damaged, however I can see a faint black spot where the firing button connected with the battery.
Yes. New batteries a multi meter and more practice. You gotta find the short with something other than firing the mod. Read and practice safety. I did that and have never had a short. Educate yourself so you are in control of your vaping safety. Not your friend.
Agreed.
Do your batteries fit snugly in your mod? If you shake it is there a rattle? If so it is bad. You need to make adjustments to make the battery fit snugly.
Again, I point out you didn't say what ohm coil you have running. Even a 30 amp Sony battery has limits, and can vent hard if you have a short in your mod or atty. A battery which got really hot could have internal damage not visible from the exterior.
