Batteries in Pocket....

[SpinDr480]

Ok this is kind of scary, and hopefully I finally learned my lesson. I just was curious if anyone knows the reason this happens.

Anyway, I carry extra 18350 batteries in my pocket when I go out to make sure I have enough battery life. One day, I put them in my pocket started feeling my let burning and reached in and one of my spare batteries was scorching hot. It actually ruined the battery since it wouldn't ever charge again.

Since I had two spare batteries in my pocket I thought it had something to do with the two touching and creating some electrical charge. However, yesterday the same thing happened with only one battery in my pocket. It just started getting really hot and I took it out of pocket and could hardly hold it. I did have a spare key in that pocket.

Anyway, I was wondering if the battery is getting hot by touching other pieces of metal in my pocket or is it from static electricity? Also, these are AW IMR batteries, so they aren't the cheapo kind.

Thanks

that's why you keep batteries in cases.

 

[SuperLuckyLady]

Yes, anything metal will do it. Ditto the advice above - a cheap safety measure.

 

[gr1llmeacheese]

Yep, battery shorted. Carrying case of some sort solves it.

 

[djezewski]

My sympathies. I just lost a EE2 battery doing something stupid. 8-o

These batteries hold a lot of power; you *must* treat them with respect, because they have no problem with biting you! They will happily make pocket change glow...

Use a carrying case, plastic cover or enclosure, or if in a jam, wrap them with electrical tape, end over end.

If your battery is on your pocket and not in one of these you deserve what you get.

Thats why they sell those lil plastic boxes.
Thanks for sharing op

Always respect the batteries.
You were lucky there. Think about what part of your body was close to the battery and what kind of damage could have been done by a hot venting lithium battery!

Plus the possible embarrassment of frantic stripping, and/or walking around shirtless, or worse, pantless...

It's just more convenient to carry the cell in a plastic box, than a change of clothes.

I will be from now on carrying in plastic case. Thank you all for the suggestions, even to the one that thinks I deserve to have my leg blown off for not realizing I needed a plastic case!

Might be an idea to stay away from mech mods !

Put one battery in a ziplock bag. Put the other battery in another ziplock bag. Put the first and second bags in a third bag.

Or, get a cheapo case. But don't put anything other than batteries in there.

There's no reason to do that, you just have to apply proper care. RTFM.

RTFM.

+1 and +1 and +1

Any metalic metal (coins, keys) on the positive end of the battery will make an electrical circuit for the battery. Continuous drainage causes the battery to become hot and can lead to venting and thermal runaway. This releases gases hot enough to cause a severe burn or cause combustible substances to catch on fire (ie. like your pants, purse, or house).

Any time you have a chance of damaging a battery (I believe Li Ion are actually under pressure too) it's a safe bet to keep them in some sort of case

and yes...the battery and other stuff in your pocket could short and create a circuit..I have read 3x threads here on this forum of "venting in my pocket" type posts....put in em in protective case!!

To the OP. You had a battery short out and get burning hot and then tried to charge it?!?

Just a thought but perhaps some more education about batteries and how they work and the dangers they can pose would be a good idea before continuing to use a mech style mod.

 

[gthompson]

I keep mine in a plastic case at all times (except when they're on a charger of course). Why take chances?

Last time I checked, a lot of regulated mods use the same batteries as mech mods. Which mod one is using is irrelevant - what matters is to not store batteries with the terminals unprotected where they can come in contact with anything metal.
