Laptop Samsung ICR18650's?

[tyob1]

I pulled six Samsung ICR18650-22E 2200 mah batteries from a working laptop battery. They all checked at 3.9V on my multimeter. Does anyone know if these are protected ICR's? Would they be safe to use in a protected VV/VW device? I put one in a Vamo V3 and it powered on and vaped, but I didn't leave it in too long because i was unsure. The only thing I can find in google is a basic data sheet, but no amp draw info.

The exact printed info on each batt is:
SAMSUNG ICR18650-22E SDI 724

I use my harvested batteries, carefully checked, on my protected devices. Others don't.

They are not protected and the chemistry in ICR batteries is not as safe as an IMR battery. Many people will tell you to steer clear of these because of the chemistry and the fact that they aren't protected. If you check them regularly and use them in a protected VV device you should be ok but you don't know for how long.

If there is one thing I learned here, (Thanks Baditude), it's do not skimp on your batteries.

Those came out of a laptop battery? Mind = Blown

The amp limit is going to be ridiculously low. On a regulated device using PWM, my understanding is that the device briefly draws much large current than whatever you have selected.

In short, it's a really bad idea using a battery unless you *know* that the amp limit is high enough. Even then, I wouldn't use unprotected ICR batteries, and you have to assume those are unprotected - laptops and their batteries have embedded charging electronics which are very unlikely to be in the battery itself.

I spend the 11-12 bucks on the AW IMR high drains. It's worth the peace of mind. I hate spending money, but it's just one of those things. Better safe than sorry.

4.4amp max discharge. they should be safe in your vamo, but only use them in a regulated protected mod like that, and not one with much power. don't use it in a dna20 or vtr for example. Also, do you know their age, and how heavily they've been used? if they saw regular use for more than two years, id pitch them

edit: and get rid of the middle one on the left with the torn wrapper

This is very true...The batts will not preform well at these amps especially if you plan on sub ohming them.

Agreed... They will work but spend the extra bit and get some AW... Fresh of the charger I've had these baby's read 4.26 volts on the meter... Well worth the investment

This. Using batteries pulled from a laptop is a very unwise idea.

Unprotected ICR batteries should never be used in a mod, even if its a regulated mod with protective circuitry. http://www.e-cigarette-forum.com/forum/ecf-library/129569-rechargeable-batteries.html

Regulated mods use pulse current (PWM - pulse width modulation) to acheive higher voltage/wattage, which pulls more amps (up to 10 amps) than what an ICR battery has to offer (often less than 4 amps).

TECHNICAL - WHY HIGH DRAIN BATTERIES?

You should use only high drain (IMR or most hybrid) batteries in a regulated mod. All 18650 high drain batteries will have at least 10 amps. BATTERY BASICS FOR MODS: IMR OR PROTECTED ICR?

(* The Panasonic/Orbtronic NCR18650A 3100mAh and NCR18650B 3400mAh batteries are not high drain and have only a 6.8 amp limit. These are not ideal batteries for 18650 regulated mods for the above reasons.)

Is it not worth $20 - 30 to invest in batteries that are known to be safe and are correct for your equipment?

Seriously it's not worth the risk especially given the relative cheepnis of good batts... As compared to costs due to fire damage, personal injury, etc.

Thanks for all the replies guys! I'm probably going to dispose of em..

I'm not trying to salvage batteries because I can't afford any, I have a pretty good collection.. I was just interested, if they were good to go, I would consider keeping them, dont take me wrong i appreciate the input. I agree it's not worth the risk.

I do wonder if they'd do in flashlights for my rifles? I have an AR and an AK I'm looking to get some lights for.. ...Just a question.. Ive read a lot on batteries but sometimes it can get overwhelming with all the acronyms, haha! Better safe than sorry, I'll recycle them.

Better yet, I have an older HD digital camera that has some damage to the shutter (it still shoots video, but its pretty much junk to me) I may set up in the middle of my 5.5 acre back yard and create a short on one of the batteries (remotely) and try to get an ICR failure on video.

I understand the consequences of shorting such a device and what safety precautions I should use to avoid injury. I did some extensive EOD training in the Army of which I won't go into detail here.

I know this is a minority opinion, but I use mine in my protected devices with no problems whatsoever. I had them checked by an electrician and they were deemed perfectly safe. Get yours checked out before deciding to dispose of them. Just my opinion.
