That happened to me too; one of my chargers was faulty; I think a or two of my batteries probably died prematurely from that one way or the other.

I've been wondering about that; have it in mind to put a pair of 18350 batteries that came with my vamo in the freezer, but I'm worried it might do more harm than good; I'm currently using 4 18650s on a zmax and vamo and the pair of 18350s are just sitting in the original box still sealed in plastic.
A battery's capacity is independent of it's voltage. Capacity is measured in amp-hours or in our case milliAmp hours.
When the battery doesn't last long during the discharge, that's the signal that the batteries capacity is diminished. It is a nuisance, but not necessarily a safety issue. Who wants to change out bats twice a day when new bats go for a full day?
Me! Me! Me! Why? Because I'm an incredibly cheap SOB.
My batteries degrade through a sequence--newest is my backup go-to when out, #2 is my go-to when out, #3 is by my computer.
When #3 finally gets incredibly annoying, it gets retired and everybody moves down a spot. A new battery goes into the newest slot.
I haven't heard of any safety issues with battery age and reduced capacity (of course, dropping voltage too far is an issue but that's not the case here). If anybody knows of any, please enlighten me and I Shall Reform My Ways.
I've never fired a gun so I couldn't tell you what one sounds like. Let's just say the bang was loud enough that his comparison was to what he has heard on TV of what a gun sounds like.. There are people still left in this society that do not have guns or have used them. I'm not Anti gun, I am pro people making their own decisions and choices.
It sounds like you have some Libertarian leanings. This is a very good thing.
Please note that I made an error in my original post; I've changed it now and lost my likes.
I said mAh to describe the charging current, but that is not correct; I should have said mA, as we are talking about a constant current supply to charge the battery.
It's only the batteries that are mAh described; so if you have a 1000mAh battery, that means it could supply one amp for an hour, or half an amp for 2 hours.
Sorry about that.
@Fast and Furious, let me tell you a story about ammunition cans...
About twenty years ago I was asked to deal with the pyrotechnics for a stage show. I did my research, built a control desk powered by a couple of car batteries and developed an igniter for flash powder (just a piece of fuse wire shorted across 12V.) I also had some stage maroons, tiny things about quarter to half the size of an eGo battery. They were reasonably expensive and I knew the requirements, so I didn't try them out before the dress rehearsal. As a precaution I took the kit out onto the balcony to fire the first one. I put is in an ammo box, not sure of the size, maybe 6-8 inches long and deep by 3 inches wide? I just rested the lid on top, as I knew I didn't want to contain the explosion, but I wanted to contain any flying debris.
When I pressed the button, there was an almighty bang, the box opened up like a fruit bowl and the (previously hinged) lid flew so high that we had several seconds to wonder where it had gone before it landed.
And that was a small maroon. They come in medium and large as well.
The idea of using pyrotechnics was shelved by common agreement.

I will state the obvious. Li-ion batteries are inappropriate for vaping. Not only are they a danger to those who use them, other peeps in their vicinity are also put at risk. And they are a risk to property, public and private. For those wanting to ban ecigs in public places, the danger of Li-ion batteries is certainly a valid reason. I won't go door-to-door evangelizing, but if the subject comes up, I would suggest to anybody using Li-ions that they would do better to use NiMh. I would certainly never give a Li-ion powered ecig device to anybody I cared about, especially to old peeps.
I will anticipate some of the rebuttals:
Here [in] the United States of America, land of the free and home of the brave, we have the God-given right to vape with Li-ion batteries.
Other types of batteries, notably NiMH, are not powerful enough for vaping. Too big and too heavy.
We can't abandon Li-ion now because the whole ecig infrastructure is built around them.
So what if a few dozen peeps a year get hammered by Li-ions? They get what they deserve for not learning and scrupulously following the rules of battery safety.
We use Li-ions in our phones, tablets, and notebooks. You want to ban those too?
I expect all the rebuttals will be similar bullcrap.
I haven't read all the replies in this thread, but I would not be surprised if some fool suggested that we should [not] publicize battery mishaps because it might give the government ammunition to use against us. I have seen that suggestion in other similar threads.

My original Ego batteries came with a note stating they were only good for 1-3 months (go figure)
My recent battery purchases state 300 or so charge cycles and they are "past best"
I'm wondering, after a year, if that battery shouldn't have been retired a while ago.
Glad it wasn't catastrophic, though. These batteries are not to be messed with

Not to pick on you zapped, just wanted to point out a couple of issues with your battery info.
DaveOno already addressed that battery capacity is not related to battery voltage.
Sub ohm vaping does not shorten charging cycles considerably. Sure, the harder you push any battery in any of a number of ways, the quicker they will degrade. I used a couple of MNKEs for over a year and a half mostly at around 0.6 ohms. That's 6 amp draw on batteries capable of delivering 20A continuously, not really pushing them at all. Ran them down to 2.5V a few times too which is not good for them. I retired them because the voltage drop under load was getting high even though the life of a charge was still not bad. Not sure how many charge cycles they had, but it was up there. They might have lasted a few cycles longer if I had only pulled 3A from them, but then I would have bought batteries that are only rated for 10A (for the extra mAh) and I would have been back to using about 1/3 of their amp capability.
Battery University is a great resource for reading up on all types of batteries. It's considered pretty accurate. Here's the page on How to Prolong Lithium-based Batteries.
A whole bunch of good stuff about lithium ion batteries, how they degrade over charge cycles, how temperature and storage affects them, how depth of discharge and percentage of full charge affect them, how to make them last longer and I think I forgot a couple. All good stuff
Well do you have a passthrough battery?
I'm trying myself to figure out how much longer a passtru battery might continue to be useable after the battery itself no longer holds much charge.
And as an incredibly cheap SOB, I assume you got one o these like me, right?
I do, I use a Volt X2. However, with a passthrough battery, you're drawing off the battery. If the battery is discharged, you have no power until it charges a bit.
Eventually, battery life is so short that you overstep the battery capacity faster than it can charge back up.
Also, keeping it on passthrough is a battery killer. You're continuously topping off a new battery, which is not a good place to be. It'd be smarter to pull it off, half charge it, and repeat.
Nope. My best USB wall plug-in can supply 1.1 A of power, or 5.5 watts maximum. I'd need to buy a better one.
"charges a bit" as in when the battery is pretty much dead anyway and CAN ONLY "charge a bit".
1: Eventually, battery life on a non-passthrough is so short you just toss the battery: how short would that be?
2: Eventually, battery life on a passthrough is so short that you overstep the battery capacity faster than it can charge back up.
A whole lot shorter than 1 above.
Like I said
Not talking about a new battery; talking about a battery that doesn't hold much charge.[/quote]
I got an Enercell from radio shack ; 2 port; 1 port at 2A, the other at 1A; a wall adapter and a car adapter.
If you're really an " incredibly cheap SOB" you'll at least TRY working it as a passthrough when it is otherwise dead.
All you really need for 1 vape is 2 amps for 5 seconds; that's 0.17 ampminutes = 170 mAminutes = 3 mAh.
seems to me you could take 1 vape a minute when your passthrough is all the way down to about 10 mAh.
A regular non-passthrough battery you'd probably toss long before that - maybe when it's down to 100 mAh.
I wouldn't go so far to say that Li-ion batteries are inappropriate for vaping. They are "reasonably safe" IF the person using them is knowledgeable to safe battery practices. Education is the key. Because I had a battery explode in my first mechanical mod (because of unsafe battery practice), I have been on a sort of Battery Safety Crusade here on ECF.
I first educated myself to be knowledgeable about Li-ion batteries. I presently participate in nearly all of the battery discussions on the forum and have created two blogs on mod batteries which have become a popular resource to ECF. Even PBusardo is using my list of recommended IMR and hybrid batteries with their specifications on his Taste Your Juice website.
I'm not saying this to pat myself on the back. I want all vapers to be knowledgeable about battery safety. The last thing we need to do is to hide battery incidents under the rug. I post photos of batteries which have vented in thermal runaway not for sensationalism or fear mongering, but because too often people are ignorant of the potential dangers of batteries and take it for granted that a battery is completely safe.
Lithium batteries are the best batteries we have to perform for our needs and expectations. I'm doing my best to get vapers to stop using the older technology protected ICR Li-Ion batteries and use the newer and safer chemistry IMR Li-Mn and hybrid batteries. Progress is being made in battery chemistry. As advanced personal vaporizers become more commonplace, the battery engineers will be more inclined to design batteries more for our purposes. We have seen this with the latest ultra-high amp batteries for sub-ohm vaping. A need existed and a solution was created.
I gave my 18 year old daughter her first mod setup for her birthday. It's what she specifically asked for - purple and pink mechanical BB's. I taught her about battery safety practices and she is fully aware of the battery incident that I had and why it occured. I have no more issues with her using an IMR safe chemistry battery in a mechanical mod than I would for myself.
That's my rant.

Think lipo's at 5 volts are bad? Heres what 460 volts three phase at 100 amps does when things go south.
Just a little exciting that day.
Just a little exciting that day.
Just thinking (warning! Stand back!) Lithium is a naturally reactive element, that's what makes it such a good energy storage medium. Unfortunately that also makes it touchy if mishandled. As my pics above show any energy storage/transfer device or medum can do unpleasantly exiting things, sometimes with very little provocation. Another thought (uh oh,,,) if lipo's are not appropriate for vaping what's gonna happen when the first fuel cell mod comes out?
Half of humanity, through no fault of their own, has an IQ at or below 100. There are plenty grandpa and grandma vapers who, although sharp in their youth, are now experiencing cognitive decline. Multimeters, Lipo charging bags, the algebra associated with Ohm's Law, battery chemistry, and other such onerous baggage is too much for some to bear. Even battery gurus who know it all have mishaps.
The notion that Li-ion batteries are the best for vaping began as a myth and has become a lie, since there is now much info and experience to the contrary.
"Lithium batteries are the best batteries we have to perform for our needs and expectations."
That statement is demonstrably false. Plenty peeps vape happily with NiMH.
Which came first -- the chicken or the egg? Is there so little mention of NiMH batteries on this forum and on others because they are used by such a small minority? Or, do forums discourage the use of NiMH and ensure only a minority will consider them by [perpetuating] the lie that Li-ion batteries are the best and safest?

You use NiMH batteries and love them. Good for you. You're actually the only person I know who still uses them.
I gave them a whirl for about 3 weeks and found them to be unsatisfactory. I get MUCH BETTER results with IMR safe-chemistry high-drain batteries and I'm comfortable with their safety risk. To each his own.
You made a bold statement yourself about "there is now much info and experience to the contrary". If you want to make a statement like that, document your sources with a link or two. I've got an open mind.
