Urgent battery heat/safety advice needed!!!

[Monotremata]

Ok, I just moved yesterday, Im about two hours away from where I was living. THOUGHT I had all my vape gear with me but apparently an LG HE2, HE4 and 2 Sammy 25rs went into my storage unit out in Coachella CA (guess Im stuck with the batteries that in both my Sig Minis now heh). Coachella can reach 110+ in the summer, my storage unit does not have an AC in it. Im now worried that those things could possibly overheat in that thing and take out my guitars/computer/records/everything.. Theyre sitting in their plastic cases but I imagine its still gonna get pretty warm in there (my unit IS an inside unit if that matters, its not one of the ones that has an outside door access).. Do I need to get my .... back over there ASAP and find those?? I seriously cant lose any of that stuff, so I figured ECF would know the answer! (Calling Mr Baditude!!!!!) Not sure what kinda heat they can take, but I started worrying when my step brother told me about his friend that had one vent/blow just from it sitting in his black car with black leather interior with the windows up and burning up his backseat. Its bad enough I left 2 liters of PG and VG in there so I cant even make juice at the moment!!!!

Im sorry that happened. High heat in cars can make batteries vent. It happened to me just driving around with the safety on off.

I would get yourself back there ASAP. Not only for all your valuables but I would feel its my responsibility for other peoples valuables and possibly their lives. What if something happens and someone is in their nearby unit ?

Im not an expert, but my logic says GO BACK !!! I hope you get some more technical answers.

Practically all 18650s are rated to 75 degrees celsius max NORMAL discharging temperature, thats 170 degrees fahrenheit of normal operating temperature before you can even expect anything to go wrong with the disconnected battery itself, let alone worry about runaway heating which would happen at a much higher temperature anyways.
Theres no urgency to go get them, but of course letting batteries sit for a long time can wear out their usefulness (usually is only a problem with LONG times, humid environments, or overcharged/undercharged batteries sitting around)
But worrying about some random catastrophic battery failure just from a semi-hot garage? No way
Now, worrying about one rolling off the table and landing top-down in scrap metal, causing it to fire all day and vent? Thats a legit concern
These 18650s are tough as .... and chemically simple, by far the biggest danger that comes with these things is overdischarge/amp limit and VERY high heat (high enough to react the lithium inside the battery with almost no oxygen, that needs to be REALLY hot to make a non-firing battery burst)
Also that being said, an exploding battery is dangerous, but its not going to blow out a corner of your house, its like a firecracker times 20. Dangerous and really hot, especially if next to your face, but its not going to destroy all of your stuff in the garage

I assume the storage unit has no windows and isn't painted black? Then it won't get excessively hot. The reason cars get hot is because of all the glass and the conducting metal. Even then I doubt the air temperature gets much over 60C. Unless you think a pan of water in the storage unit would start to boil, I very much doubt you will have problems.

And they are IMR batteries, right? So if they do vent, they shouldn't catch fire.

The thing is heat will effect the life of the batteries if they stayed there for a long time. You are ok until you can get them. LG HE2

• LG HE2 Storage Temperature (40% charged): 1 month -20 ~ 60°C, 3 month -20 ~ 45°C, 1 year -20 ~ 20°C,

Man you guys rule. I'll stop freaking out now he he. I have a friend who makes juice and her husband runs a vape shop out in Texas who told me to quit freaking out because they're not even in mods but I wanted confirmation from the ECF to be sure. I won't be going to get my stuff (aka most of my recording studio and crap that wouldn't fit in my car) until shortly before my first month runs out so at least I don't need to make an emergency trip out there. The good thing, I remembered exactly where they are, I put them in their plastic cases into a Beatles lunch box, so at least they didn't go in a cardboard box that might combust if they vent. I read an article earlier about LiPos exploding when they got to something like 200+F so it made me feel a little better. Only problem now is I have 1 HE4 for my dripper Sig mini and 1 HE2 for my tank mini so I'll just be careful using the built in chargers so I don't have a "Cloupor incident" heh.. I dont care about battery life, thats easy to replace i just dreaded getting a call that i set the unit on fire and everything was gone. Now I just hope my non-safe chemistry vinyl records don't warp!

If they were ICR, Ni-Mn, or Li-Po chemistry batteries I'd be more concerned about flame, fire, or explosion.

Being that they are Li-Mn, IMR, or safe chemistry batteries, they are more tolerant to heat. However, strange things have always been known to happen, so if it was me and my valued possessions, I'd still retrieve those batteries at my "earliest convenience".
