If you want to store Li-ion batteries the best you can do is to have them charged around 40-60%. I prefer 40. Lithium batteries do not like high voltages during storing.
Any battery regardless of the chemistry looses energy during storage. But that differs from one chemistry to another.

I'd also say it depends on what you mean, exactly, by "storage". If it's only a few days to a few weeks, that's one thing. If it's months or longer, that's a different ball game.
Then you don't have to do anything, you can fully charge them and use them normally.
WOW Mine didn't take that long at all and I charged all 4 at the same time. Maybe yours had a lower charge when you recieved them.
I charged all 4 at the same time on the same charger and I would say it took about 3 hours give or take..

If you use low charging current charger (you did not tell us which charger??) then 5to6 hours is normal.
If you use 1000mAh charging current charger (Xtar, Soshine), then it shouldn't be over 2.5 to 4 hours. Depends on battery depletion level.
Jetbeam, and Nitecore 2 channel chargers use only 500mA to charge 18650 batteries. That is one reason why your charging is taking so long. Nothing wrong with these chargers, if you do not mind charging time.
3400mAh will take over 11 hrs to fully charge, so you are still good with your ch. time.
My efest 18650's take over 12 hours to fully charge in my trustfire TR-001 charger
using the 2500mah trustfires, button tops that came with the vamo from fastech, no issues so far
Since were talking chargers I would be grateful for some guidance. For my Vamo 3 I have AW IMR 18650, AW IMR 18350, and Efest IMR 18650 bats which I charge with my XTAR VPI. My questions:
If time to charge is NOT a concern will I get a better charge using 0.25 A charging current? When I say better charge I'm assuming that means better saturation and battery life but I'm not sure? Is their any evidence that in this case the bat lasts longer in my Vamo 3?
If I select 1.00 A charging current for my bats then the time to charge is faster. That much I understand. However, what if any are the tradeoffs when compared to a 0.25 A charging current?
As you can see, I'm not a bat geek
and when I look at graphs I glaze over so any plain English non geek help would be great.

Generally speaking, and I am anything but a battery expert, keeping charge rates at low or moderate levels is probably better for any battery type simply to keep internal heating down to a minimum. Less heating equals longer life as a general rule of thumb. I suspect that charge rates of 500ma are pretty close to optimal. The thing to consider is the total output capability of the charger, IE is it 500ma or 1amp total versus per channel?
Maybe time for new charger? That doesn't sound to trusty to me
Yeah it doesn't, does it? Its less than a month old & the batteries are too. I've been a little concerned because it takes so long to charge my 18650's. Is there any safety risk to long charging times or is it just an annoyance?
Btw, it doesn't have the same problem with my 18350's. They reach full charge in about 3 hours

18350's are generally 800mah batteries, about a third of the current capacity of your 18650's. The charge times make sense, based on that.
In Li-ion batteries the normal charging current is 0.7C (varies 0.1C between manufacturers) in the case of the panasonic 1323,529411764706mA Anything below will only charge the battery slower without any other effect. Anything above will destroy the battery. 500mA is almost twice lower.
Efest 18650s on a trustfire take forever.. 6+
Good thing I'll get the days off a fresh one.

i have quite a long charge time as well but i figured it was becase of the 2600 mah and they want to put the v in slowly, no isues just what i have noticed
