18650's from Laptop

[ILoveNorCal]

I just got 9 new 18650 batteries FOR FREE!!!

yes, as many of you probably know, most laptop batteries are built with 18650's all tied together... so, it being in my nature to recycle (being from Nor Cal and all) and it being even more in my nature to destroy things... I decide to combine both of those things and brutally rip apart an old laptop battery.

Now, can someone give me some valid reason why I shouldn't use these batteries?

Protip: Not being able to blow fat clouds is not a valid reason. I am not a cloud chaser.

I mean real reasons, like i'm going to kill myself.

You don't say what type of 18650's they are. If they're li-ion's they're going to be unprotected and shouldn't be used for vaping. If they're limn's you might be ok. Chances are they're li-ion's though. Besides if they're from an old laptop they've probably been well used so they might not hold a charge very well. I know I replace the 18650's for my mods every 6 months or so.

It would be more of a black market ecig thing than a thing to do when you can buy new known batteries.

As above, probably un-protected ICR chemistry batteries and not fit for use in a mod. They are worthless.

Don't even think about putting those in a regulated mod because it has its own protection circuitry. ICR batteries will only have an amp limit of 3 - 4 amps, not nearly what is required for the pulse regulation of a variable voltage mod. Using one of these batteries would at worse overwhelm it and likely cause it to go into thermal runaway; at best shut the mod down if you're lucky.

Unprotected use in a mechanical mod would be creating a pipe bomb waiting to explode.

Do yourself a favor and dispose of the batteries properly. I believe places like Radio Shack will accept them for proper disposal. Don't be like this fella.

Wow. Just wow. It's actions like this that keep mainstream media full of ammo against an otherwise safe alterrnative/hobby. Don't get me wrong, I'm all for recycling and repurposing, but C'mon. Safety first people. Remeidial Vaping 101.

Now on the other hand... If your cool with puffing on a pipe bomb, by all means go for it. Just please help us all out first, and hang your sign around your neck.

The good thing is he came onto the board to ask if it would be safe before using them. Now lets see if he follows sound advice, or is bull-headed and tries to prove everyone is wrong. You can lead a horse to water, but ...

the guy obviously doesnt know they could be dangerous. he did the right thing by asking the question. i think he did put safety first in asking the people that would know. Responses like that will make people not want to ask questions. if the OP would have said he is using the batteries, your statement may have been valid.

Sure.

Laptop batteries are designed for constant, low current drain. If you check the specs on those batteries you will probably find they are designed to drain at a rate of only 500 - 700 mA - which is way below the current demands of vaping.

If you check the manufacturers specs you will find all sorts of design criteria for the safe protection and charging circuits to be used with those batteries. You have just ripped those batteries away from the appropriate protection and charging circuits designed by the manufacturer to be used specifically with those batteries in packs.

If you can't find the manufacturer specs you don't have a clue what the safe discharge rate is. Period. You don't use batteries you cannot research.

They are now unprotected ICR chemistry batteries. If anything was going to blow up on you in e-cig use - that would be it.

^^^^^^^ all good replies, head the advise.
I too am in Nor-Cal and recycling is cool... BUT it's only new, OE batteries for me.

 

[powerband]

Never mind... ha ha

 

[Rickajho]

How are the batteries marked? I would think that an 18650 is an 18650.

When it comes to Li-On batteries, several different chemical combinations used to create them, their safe discharge rate, their design with protection, if any - that is extremely not true. It's akin to saying "I would think an automobile is an automobile."

Nothing could be further from the truth. Different battery chemistries are only applicable to different applications. We have three types of batteries that are currently used in APV's. Protected ICR (cobalt li-ion), unprotected safe-chemistry high-drain IMR (li-mn), and the new hybrids (mix of cobalt, manganese, nickle, and others). All of them are stronger in one application than others.

lots of good advice above...

OP- i'm also in Sac. please don't use those in my part of town

 

[ILoveNorCal]

Yeah, I didn't really think they would work... but I thought it would be worth looking into.

At best I thought, they wouldn't be ideal, but maybe at least usable... ya know, without blowing up.

And for the record, I tried to post pictures, but they kept failing to upload and I was in a hurry.
