Did I damage my battery? Worried (AWT IMR 18650 40A)

[OCDP]

Hi there,

I recently purchased an ipv D2. Today at work I noticed my battery low, and decided I'd charge it via the onboard charging port which uses a 5V DC wall charger. Being in a rush at the office, I noticed we had a wall charger, and it fit the connection. I plugged it in for ~10 seconds before noticing on the adapter that it's ouput is 9V and not 5V. I immediately unplugged it, not thinking much about it (being in a rush...)

Silly me goes for lunch, sets the mod on the table and go about my business. After about ~40 minutes I get ready to leave, pick up my mod and notice it's warm. Not hot at all, but quite warm. Immediately I remove the battery and set things aside. Everything has cooled down now, and all seems well.

My question and massive concern here is: Did I fry my battery and or mod? I am assuming that this battery should not be used again, is this correct? It's brand new, used roughly 1.5 weeks. This whole situation alarmed me, and believe me when I say this is the first and last (and only) time I will ever make this mistake. I am usually over-paranoid with battery safety, so having done this is really disappointing. I am genuinely worried my battery will explode. Not sure how likely this is.

Thanks for your time

My one and only question is:

Was the table exposed to a Sunny window?

I ask because:
1) the brief mistake should have had No effect on the Battery.
2) The Mod controls output so nothing should have been operating.
3) There is a great difference in warm and HOT

At worse, you could possibly damage the mods charge circuit or maybe fry the board.
If it is working, the Board is good to go.
Next test would be Charging from a proper adapter.
Batteries will get warm when charging and when discharging. This is normal. HOT is not normal.

Okay, enough gabber - you should be good to go.

Yes, I own a IPV-D2

Thanks for the quick reply!

The mod was on a table, but no sunshine unfortunately. The actual battery inside the mod was warm as well as the mod itself. I also had a silicone case on it, which could have held the heat in more. It never got hot, by no stretch of the imagination was it hot. Quite warm though, I would say slightly warmer than what I'm used to and have seen in my years of vaping (ie: from heavy usage) It just felt "off" if that makes any sense?

If worst case is I fried the circuit board am I still okay to use the mod otherwise? I am fearful of putting the battery back into the mod. I have never, ever charged a battery through the mod itself. I always use external battery chargers, but today I was in a rush and have to go out after work so thought I'd try. Serves me right!

Usually when you fry something you know it by the smell of ozone in the air

Could be you were worried about it and it just felt warmer than you thought it should but wasn't

Most batteries heat up during charging, especially a rapid charge. Being a 9v source instead of 5v the charging board in the mod would have fried before the battery. When charging, milliamps and amps are more considered than voltage, the charging board handles the voltage conversion. Most onboard chargers, especially as you said the mod was in a silicon sleeve warm up when charging a battery anyway, just make sure to take the sleeve off the mod when charging to allow adequate battery ventilation next time.

It's probably fine and if it was me I'd just keep an eye on it and don't leave it inside a mod overnight just to be sure.
If you're really worried about it being damaged just replace it, batteries are a couple of bucks each.

I'm sure it's fine though if it was only warm and not scorching hot or anything.

so it seems to be working fine now?
If any damage I would think it was in the charging circuit and not the battery. But I cannot be certain.
If it appears ok I would be cautious with it for a few days. NO unsupervised charging and do not leave the battery in it unattended.

That is of course not a 40 amp battery, most likely 20 amps CDR btw.

I still haven't put the battery back in, been taking in as much input and feedback as I can before doing so. I appreciate all the responses so far.

The mod was definitely warmer than it should have been. As I mentioned, I plugged the 9V charger in for no more than 15 seconds, put it in my pocket, then put it on a table in the lunch room. It was only "charging" for 15 seconds tops, and it kept the mod warm for 45 minutes. If I hadn't picked the mod up or left it unattended I am wondering if the temperature would have continued to rise or not? Or was the silicone case acting as insulation and keeping the mod/battery warm for so long? The warmth was similar to heavy chain vaping, maybe a bit warmer, but far from hot. I definitely knew something was up, just not sure what. When I smell the inside of the battery bay it has that distinct circuitry smell, but am unsure if that smell was present before and after the incident.

The battery states it's 40 amps, but am unsure of the validity of that. It's almost brand new as well, only been charged about 4 times.

Going off of all of your responses, it sounds like I should be OK to put it back in the mod supervised, using caution. I am weary, as I am always over-paranoid with battery safety.

warm like a cup of coffie warm? or warm like a black car hood in the summer in Nevada warm? I have found battery charging can become warm 110-125F and have no ill effects, but really warm as in dont touch it to your lips too warm is a reason to be concerned...

ohh and BTW... no such thing as an 18XXX 40A battery... ever hear of a 3000 HP go cart motor?

 

[IMFire3605]

Don't trust the 40amp rating, Panasonic, Sony, LG, and Samsung, the big 4 battery manufacturers do not make any batteries over 30amp CDR. AWT is a re-wrap company like Efest, IMRen, MXJO, and several others that buy b and c bin discards from the big 4, re-wrap and put the Pulse Discharge Rating on the wrapper and charge double what an Authentic A Bin cell costs. So trust the battery is only a 20amp CDR battery at best, if the battery was excessively warm from the incident, like 20 degrees F over body temperature, recycle it and get another, I wouldn't risk it, if it was just mildly warm to the touch you should be fine.

50K watt close enough?




edit...lol, guess not that's like 67hp only

Warm like a cup of coffee, probably cooler. It happened fast and I panicked and removed that battery as fast as possible. But definitely far from hot. I put the battery back in the mod and everything started up normally, it's firing (but I am at work in an office setting so can't vape) but so far, it hasn't increased in temperature. I am watching it like a hawk. From the sounds of things, this battery can get warm like it did without issue, but I ALWAYS play it safe. It's not worth the risk.

Very interesting and good to know on these AWT batteries. I had a suspicion about them, seemed way too good to be true, but I trusted my "reliable" local vape shop. I'll read up on that blog as I won't be purchasing them again. The only other batteries I own are Sony VTC 4 and 5's, and one LG HE2(?) I believe it's called. This is the only one I ventured away from the norm for.
