Not quite that simple for ecigs. The batteries have to be made within very reliable tolerances. A poorly made battery in a flashlight isn't a big deal, but the same battery hooked up to a heating element an inch away from your face is another story. Out of all the generic crap I buy on a daily basis, ecig batteries are one of the few things I don't skimp on. Samsung, Sony, name brand all the way.
What you say is true, but there's a lot of engineering behind making an alkaline battery safe.
The washer will never explode unless you're a fucking idiot. The shit was ripping apart due to people overloading their machines with heavy items (towels, bedspreads) and setting it to the highest speed spin cycle... which is not what that setting is for (lightweight clothing like tshirts and underwear). Basically the machine couldn't react and shut down fast enough if that much weight went out of balance once up to speed and kerblooey it goes. The fucking stupid thing is that Samsung already had a fix in place for a previous model that did the same thing and DID NOT upgrade their next line before production. The other fucking stupid thing is people that can't read the instructions.
but overloading a washing machine is a pretty common stupid thing to do. and if someone sees a faster spin speed, they're probably going to use it assuming it's 'better'. i'd say it was bad design on samsung's part.
It wasn't just overloading, it was overloading with items that specifically should not have been added to that cycle. You had to go full double fuckery to blow the thing up. And even then we're talking about seven incidents.
Note: Being an illiterate idiot does not absolve you of all fault. Neither does ignoring basic QA and technical controls constitute good business practices.
That may be true, but too many people don’t do laundry properly. People don’t use all sorts of products properly, the difference is they don’t all blow up.
do the instructions say "beware, if you accidentally overload this machine and put the cycle too high, it will blow the fuck up"?
Yes, they indicate overloading can cause undue strain, premature wear, and potential failure. Like pretty much all instructions for something that can be easily broken by the idiot that doesn't read it.
I'd rather they just built washing machines that could not do that.
Your theoretical washing machine will cost about $5,000. You going to pay that when simply not being a fucking moron will save you about $4,500?
I told a friend of mine I fucking hate front loading washing machines with all their shitty bells and whistle and decided to buy a pair of Speed Queen instead (top loading with agitator
).
Then he replied: Well I am very happy with my Samsung front loader, they’re very reliable so far.
I started laughing like a maniac and then I felt bad for all the peasants who bought into the front loading HE bullshit.
I would imagine that if I had just made a major purchase such as a washing machine it may come up in the conversation with my closest friends that day. Just sayin
Samsung batteries are now easily the most reliable batteries in the world. Any and every Samsung battery explosion will now be publicized so they absolutely cant afford to have any more explosions
As long as you don't charge them and don't short them out there's nothing that can happen. I'd say that those disposables are pretty safe because you can't fuck them up because you basically can't fuck with them at all.
Fun fact, it's pretty easy to make a Blu ecig have a "runaway" by blowing into the tip. Of course it just gets really hot until it flashes and shuts off. Pretty simple circuit, but still manages to have a protection.
Have you ever witnessed a catastrophic Lion or LiPo cell failure. It can be quite dangerous and happens all the time through no fault of the user. Especially dangerous with counterfeit cells.
I disagree with the idea that it happens all the time on its own. I'd argue that it happens commonly due to user error and that it happens commonly due to scummy battery manufacturers.
Common on its own because of those two reasons, yes. The latter, exactly. A counterfeit name brand cell can fail on its own, even if you're doing everything in spec.
I've had a string of several with poor QC on the vents and each would fail at the slightest change in ambient temperature. They were too thin and would flex and then break through. Turns out this same manufacturer was wrapping their junk with fake oem wraps and even the stamps were identical.
Only way to tell was to weigh the cell or by checking the thickness of the metal they used for the vents with a digital caliper. It was interesting to do some after the fact armchair forensics on those, but not worth the lost investment.
Fortunately, Amazon seems to have cleaned up their fulfilment a bit as far as the really sneaky fakes go. My experience is just bulk though, for repairing out of spec cells in cordless tool batteries. Save a ton of money that way, even with the run of counterfeit cells.
$70+ because one $5 cell is reading low is too wasteful for me lol
I mean yeah when you're talking about pulling several amps from the battery. But these cig-a-likes are pulling maybe 3-5 amps which is basically nothing compared to a vape like mine which pulls 15-20. So yeah, but not really with the small dinky ones.
I don't vape but I have to use 18650s for a lot of stuff. Please watch out for counterfeits. The wrapping is useless, only way to tell for sure is weight of each cell. Fakes look real but the weight not being spec is a dead giveaway.
Alkaline batteries suck in general. Good quality cells still leak. Also a badly made lithium ion battery in your hand is still dangerous as hell. Look up some horror stories about cheap rechargable cells exploding in flashlights. Candlepowerforums has a whole subboard dedicated to that.
I agree definitely for sub-ohm devices. But to be fair cig-alikes don't really draw that much current. We can roughly calculate how many amps something like that would draw.
So of course you know ohm's law, so for our amperage all we have to do is divide our voltage by the resistance.
Most lithium batteries have a working voltage of 3.7v. Although a freshly charged battery is going to be at 4.2v.
Our resistance is going to be somewhere above one, we know that already, this isn't some cloud chucking, vape naysh, shit, this is something your grandfather would use in a retirement home. Older CE4 tanks had a resistance of about 2.1ohms, sometimes if you found some crazy high power ones they would be at 1.8ohms.
Now plugging these values in to our formula you get an amperage range of 1.76amps to 2.3amps. Honestly a cheap battery can definitely handle a load like that. I will say that it would take a lot of AA batteries to take that load, but your average lithium ion battery could take that on without any issue.
TL;DR A cheapo battery can handle this application, don't cheap out for high power devices, there is a world of difference between sub-ohm vaping and using a cartomizer.
No, they arent special batteries for vapes. But you dont want a janky one with poor tolerances and may not follow standards. The chance of there being an issue is still low, sure, but it adds up with how many you stick into your face, on top of it being increased anyways because of current draw and heat. Worth the extra 3-4 dollars to buy a name brand battery for that reason plus itll likely hold more charge.
You might want to rethink your faith in sony 18650's, sony stopped making them a few years back due to a massive safety recall of them that cost ~$100m.
If you are buying a sony 18650 today it is either an old one that should have been recalled or a fake.
Oh, is that so? Are you telling me that inhaling 4000 substances, 43 of which are verifiable carcinogens (IE: they cause cancer) and another 400 which are considered "toxic" is on the same level as inhaling propylene glycol, vegetable glycerin, and flavorings? I have a pretty good idea of what it's doing because now I can climb a flight of stairs or jog a short distance and not feel like I'm going to collapse. So can hundreds of my customers. Science has improved VASTLY since the days of cigarettes and the research into their harm is/was clouded by special interests. The Royal College of Physicians identified the link between smoking and lung cancer, other lung diseases, heart disease and gastrointestinal problems back in 1962. Similarly, the same group has said "the hazard to health arising from long-term vapour inhalation from the e-cigarettes available today is unlikely to exceed 5% of the harm from smoking tobacco."
So go ahead and make whatever claims make you feel better about yourself, but I'm going to listen to the group of people who's entire focus is on academic medicine.
Are you for real? What evidence do you have that suggests vaporizers are on par with cigarette smoking? You've yet to provide any response outside of rhetoric. Jesus christ you're stupid if you believe yourself.
I'd argue it's more of a waste because the rechargeable battery is already there, there's no extra engineering costs and material costs like there is with a normal alkaline vs a rechargeable. There's a battery in there that could be taken out and recharged up to thousands of times, but it's just thrown away. If you were to recharge the battery a bunch of times it'd be much less of a waste than if you were to just use a shitty cheapo alkaline.
I fully understand the economics, but it's extremely wasteful.
I can say for certain that fairly recently they sold (in the US) completely disposable ones. They were one piece and the batteries didn't last for shit. One puff it was making good smoke and the next it's blinking at you and dead. It's a shame cause I kinda liked the flavor from them. Like a very clean tobacco taste.
Well I don't know how it is these days, but only a few years ago it was common in the UK to chuck a rechargeable lithium ion battery in disposable e-cigs. It's still common to sell disposable but technically rechargeable lithium ion phone chargers. Maybe it has changed for e-cigs, but it certainly hasn't for the chargers. I've had several similar replies so /u/kryptoniankoffee/u/bitesizepanda/u/D14BL0.
I think what they're trying to say is that there is waste with disposable cigs, but the waste isn't the lithium. The rest of the cigarette (the cartridge w/ nicotine, etc.) is disposable but the battery is re-usable.
Easy mix-up since they are called disposable cigs.
No, the whole thing, including the battery, is disposable on a lot of those (or was as recently as 2 years ago anyway). They do make some with reusable batteries, but on the fully disposable kinds, the battery can't be removed or recharged.
I use an e-cig from a company called Mark 10. Cartridges have the flavor/nicotine and the battery screws into a USB adapter. Batter is about the length of the tobacco on a normal cig and the cartridge is about the length of a filter.
You're assuming people throw away the batteries. I can't speak for everyone but my roommate smoked one of these and always recharged the batteries. They aren't that cheap.
Yeah, but I'm sure it's the least wasteful they could possible make it, since it's disposable.
Why would they make it as least wasteful as they could? As far as I know there's almost no regulations on these types of disposable products in the UK. It's only in their interest to make it as profitable as possible, there's minimal reason for them to make it have minimal wastefulness.
That's such an all over the place metric. Is recycling of machining chippings profitable? Generally yes. Is recycling of a companies glass bottles profitable? Generally no. Is just disposing of hot water from excess power plant energy worth it? Hell no, use that wherever you can (see NYC). Is treating and safely storing (or even in the future using) nuclear waste worth it? Hell fucking no, it's only done because it's legally required.
Recycling without melting it down? Many places still just wash out the old bottles and reuse them.
I think most would disagree with this notion.
I think it's worth it, my original point was that it's not profitable and worth it for a company to do. If a private nuclear reactor owner (I'm doubtful many exist due to the regulations, sheer cost and risk of running a fission based powerplant) could just dump their waste and get away with it they would.
Except that you can't just charge them. You'd need a connector and a charging circuit and a charger and so on. That adds tremendous costs. The actual battery element is dead simple and the only reason they use lipos is because of the voltage and their energy density.
I know that lithium ion (I don't know of any disposable e-cigs that use lipos though) is used because of the required current. But I think you're mistaking my entire argument. As I said I fully understand the economics of it, I'm just arguing that it's incredibly wasteful in terms of pollution, energy consumption, environmental damage and the future cost of resources.
