Ok still not being a wiseguy here... last question before I give up. What is the safety issue? How is it safer to pull the battery out of my lavatube and let it "rest" before putting it in the charger? I don't get it...
18650 lifespan?

I've read all about Li Ion batteries, didn't see anything about resting but whatever. I'm done. Thanks for the replies. Everyone is always really nice even if they think I'm wrong.
There is an abundance of "safety" and longevity precautions that are either self-implemented or spread by misinformation. Many of which do very little, to effectively nothing, for the purpose that they are intended. But these precautions give the user peace-of-mind. To many users, peace of mind is far more valuable than the minute results of the precautions.
Resting after charging is useful only if you measure voltage sag after the rest period. Useful as a gauge of battery health. Useless if there is no history of measurements.
Another one is not discharging the battery fully will prolong battery life. So what is a full discharge? 3.6v? 3.2v? 2.8v? Technically it depends on the battery. There is variation based on the chemistry and how they are made. So much hype is generated about charging often because Battery U says it will prolong life. But when viewed for our purpose we never fully discharge a battery in the first place since either the device can't function that low or the vape is too weak to be satisfying so you change the battery before full discharge anyways.
At some point, these precautions fall into one, or both, of two categories: diminishing returns, or piece of mind.
Edit: this is obviously assuming normal conditions. If the battery is abnormally warm coming off the charger, then it should "rest" to cool down. But at the same time you should investigate why it is getting warm in the first place and not use the battery until you can say that the battery is not to blame for the heat.

Hello, Ive been searching for that type of multimeter and havent found it, where did you get it? I need a meter ASAP.
thank you
I think you could do with buying a new set of batteries, 9 bucks and using them for over a year sounds pretty cheap.
Sorry to jump in on your thread, but I have to ask... I came in here because I was curious as to how long - generally based on your personal experience and I don't care about the techy stuff - an AW IMR 18490 would last in rotation with one other, charged and rested. A week? A month? 6 months? Just generally, as I just got mine and have no clue if I will be needing to replace it in a few days or a few months and yes, I realize my mileage may vary.
Also, I have to ask if I am using an $11 battery why would I want to spend more money on the volt reader thingy (the above link shows over $50) if said battery is going to last me (based on what little I could get out of the above and would still appreciate a personal experience with these) ~ 6 months? Seems like overkill to me. You could use that money to buy a mod that has that built in.

I'd love to do just that, but the $11 batteries I bought lasted 2 months, not a year. I want to find out what I'm doing wrong (assuming the batteries themselves are up to snuff)
I guess I am doing something right.....my AW IMR 18650 batteries are about a year and a half old now and still working fine. I do let them rest before charging simply because I wait til I have 2 to charge at a time. I also let them rest simply because I have 5 of them and try to use them in order they come off the charger.
I do find that I am swapping out batteries sooner now than when I got them. But, I can't complain now seeing how long I have been using them from what I have read here. I still get about a full day out of each battery in my provairi at about 4.2 volts to a single coil carto in a tank.

Oh, sorry.. You typed june 2011, so I thought a year. If you have only 2 batteries, I would buy at least another 2, in order to switch them all around. I have 4 panasonics (around 8 bucks at orbtronic) and they last about a day and a half each, bought them all on march 3 this year.

Everyone knows its the rule of law to not use the battery's before or after charging, that's why they all do it when they charge their cell phone.

Now on a realistic note my battery's start out at 4.2 I charge them when they hit the 3.8-9 area. I pull it out and stick them on the charger and when they are charged I swap them out and keep vaping. Why? How could you abuse your battery's that way?
Because simple....I hobby in solar systems and have a lot of understanding of batteries and have full understanding that it's not the resting and all that jazz that kills battery's its the draining them down till they won't fire that kills them. They only can take a charge so many times and the further down you drain them the harder it is to charge them. A battery that runs at 20% discharge will last 5 or 6 times longer than one that gets abused by discharging it to 3.4 constantly.

High state of charge is just as damaging as a low state of charge. There is a reason that it is recommended to store Li-Ion's at a partial charge. 3.4v is far from abuse. Even 2.8v is questionable. Many battries these days can be run down to 2.5v as stated by the manufacturer.
And before someone mentions Battery University, I am fully aware of thier recomendations on prolonging battery life. As I have said before, most of the practices fall into either peace of mind, or diminishing returns. Do what makes you feel comfortable. But please don't lead others to believe than something that is well within the safe operating range is somehow abusive to thier batteries.
Also, if a battery is discharged to 75% and charged twice as often as a battery that is discharged to 50%, which one would last longer in a measurement of time? It's a rhetorical question, but it presents what I percive as a problem with measuring battery life in number of charge cycles.
