Are these high drain batteries? I am considering using these with a vaporizing device. Anyone had luck with such an application?

Not sure how you plan on using them, but you need to know your wattage needs. these battery's are rated 3.7V 5000mAh (5 amps for 1 hour) So 2.5 Amp for 2 hours, 1.25 Amps for 4 Hours, etc...

In my 'unqualified opinion' they certainly seem to be. They drive my flashlight with 7 T-6 emitters and that puppy gets hot enough to cook, or even start a fire (No, I've not ignited stuff, but then, it gets darn hot darn fast.) The batteries have PCB protection, so they hopefully protect themselves from exploding, thankfully. I'll put it this way, the amount of energy they dump appears to be on the order of a rather bright car headlight. I cannot advise about 'vaporizing' as such, however, with an inverter to a charging circuit with enough capacitance and inductance mated together, it'd surely be possible for them to be a source for enough energy to be 'charged up and dumped at will' quite handily. Think 'super stun gun,' but with one big bad jolt at higher amperage.

No but works great in my trustfire A8 flashlight and last a long long time a whole week, Great battery give it a try.

I've left them in for a reasonable period of time (life of batteries) with no ill effect, though it could possible shorten the battery life. I have no evidence, just a hunch.

No. They are 18650 batteries. Probably removed from a used up laptop battery.Ultrafire batteries are crap. You might get lucky, and get a good one, probably not.

i can't tell you, but Ive had no trouble with them. I've recharged these several times. They work well.

These batteries are comparable to AW imr batteries. I use these for my vapes and have no complaints.

I haven't specifically used these batteries for your purpose. I have, however, used them for XBox controllers, TV remotes, a battery powered razor, battery powered clocks, my home thermostat, and RC cars. In every case, the performance of the rechargeable batteries has met or exceeded the performance of standard batteries. Rechargeable work well enough that I haven't purchased a standard battery for a couple of years. One recommendation I would make though, is to buy a few more batteries than you need. This way you can simply swap the discharged batteries for some newly-charged ones right away. I know that I didn't answer your question directly, but hope it helps.

You'd have to buy lithium batteries if you want them to last longer. Otherwise, they do drain quickly...

Why yes they are! However these batteries work fine for me and who else makes them anyways? The price is right So lets vape tonight. The pair I bought are still going strong after months of day and night vaping.

Short answer - yes. However, if you try to use them after they have reached their "protected" level of discharge, you can get them to discharge so low they will not recharge.

dude, i use these in my flashlights, they are ok but yes they are low drain they stink if your going for mech mod's. but i've had to buy plenty of these for my lights but if it's for your lights try the ultrafire, 3.7V 5000mAh they work amazing and last forever. also they are low drain batteries and they are yellow.

Long as you don't plan on using the batteries until they are near death. In any case with high drain devices it's best to get a pack of batteries as they most likely were done in the same batch so there will be little differences between voltage and capacity, though even then i have noticed a profound difference in voltages in a battery pack. Otherwise mixing battery brands are not bad so as long as you are not planning to use them until near death or can monitor every individual battery to prevent over-discharging and cell reversal.

Yes, they are great since they're high drain batteries that allows you to build rebuildable atomizers in several different ways w/o the battery protection that would normally restrict you.

No i hvnt needed to i got them and charged them and when i can tell they start to drop off volts i charge them but they work ok last about 4 or more hrs before i notice voltage drop. My mod says they still are half charged but i notice the drop around 60% so i just charge them. They are good for back up so they work ok for me. I use my sony and efest batteries for when iam going out and i bring one of these just incase. But i also vape alot and at 20 or more watts so if u hv a mod thats only 15watts they would prob work verry well. I dont use them in my dna30 because they are button top and hard to get out of device. If u hv any more Q just ask.

So far, they work great. I think the key is to drop them as little as possible, as well as letting the batteries run down all the way before recharging. If this changes I will re-post.

For devices such as electronic cigarette that use variable ohms output, i.e.,1.2 to 2.5 coils. Your device manual probably species the volts, and amperage needed to work properly. I use these batteries for my evo e cigarette, they are rechargeable and durable. Good for the price. Once I bought a multiple of 4 and one of them was defective. I did not returned it, however, Amazon has a great customer service department. I have returned stuff before and never had any problems.

I've noticed the same thing. After a short time they are completely off and do not drain the battery. I don't know the reason for sure. My theory, LEDs have a broader amperage operating range and pick up the residual in the system for a short time. Just a theory.
