If it is a decently made charger, it should be OK for 6-8 hours - when the light turns green it should stop charging. But some of the not so well made ones can cause the voltage to creep up, and I have read that you do not want to go above 4.25 V on a lithium or the battery life will decline significantly. (May not be so true of the Li-Mn, IDK, but this was the case with Li-Ion.)
Edit: Li-Mn batteries are also susceptible to overcharging; shortening life cycle

Another point that needs to be made is knowing the max discharge current for your batteries. I have seen a few posts with the rebuildable atty crowd where someone is boasting about how great there ultra low resistance atty was vaping. One that stuck out was a 0.6ohm (?!?) dual coil powered by a little 18350 (!?!) mechanical mod. Asking the little battery for over 6 amps!!
In general:
ICR protected batteries should never be discharged greater than 2x it's capacity (2C). So for a 1000mAh battery X 2 = 2000mA or 2 amps. IMR and LiPoly vary widely depending on the battery and not all IMR and LiPoly cells are "high drain". I've seen IMRs rated from 2C to 15C and LiPoly from .5C to 50C. Consult the vendor or manufacturer, or post a question here in the forums.
Most important thing to remember....if you are unsure of what your batteries can do or of what you are asking from your batteries...just ask.

Good point. If you are unsure of just what your battery is capable of, a Google search on the manufacturer and model number should point you to a site that lists the specs. Do a search for lithium battery specification and you should turn up something which will explain just what the specs mean.
I can't remember if there is a sticky somewhere on the forum or not, but you could also try a quick search here, too.

There is a forum sticky, that they took some time to put together. It's here: http://www.e-cigarette-forum.com/forum/ecf-library/129569-rechargeable-batteries.html
A couple of things from that:
Our advice is that the best and the safer choice of battery for APVs is the AW IMR Li-Mn rechargeable.
And this:
Rechargeable batteries
We now advise that Li-Mn or top-quality Li-FePo4 rechargeables are used in APVs, in preference to rechargeable Li-ions. We suggest the best option, in order, is:
1. AW IMR Li-Mn rechargeables.
2. AW Li-FePo4 rechargeables [Li-FePo4's MUST HAVE A SPECIAL CHARGER]. Note that these batteries are mostly 3 volt nominal so the system voltage will be lower than normal.
3. Good quality (such as AW or Pila) protected Li-ion rechargeables.
4. Branded protected Li-ions come next - such as xxxfire Li-ion rechargeables (for xxx insert Trust / Sure / Ultra-).
5. The least-preferable option is a generic protected Li-ion.
6. Unprotected rechargeable Li-ion cells should not be used.
7. Standard cells (non-rechargeable) should not be used.
Li-FePo4 cells can be used provided that they are top-quality and have a rating of 4C or higher.

I never said that there aren't batteries being made in other countries. I stated the majority of Li-based batteries are produced in a single providence in China. That is in fact true and I've actually seen a documentary about it ages ago. There's basically one "town" (can't remember the name) whose only export are rechargeable lithium-based batteries. Everyone in that town is associated with the business in some shape and/or form.
That doesn't mean that there aren't a lot of other factories world wide. It just means that China, and that specific providence produce more than others within the global market, especially on a per capita basis.
China and Japan ... you'd be hard pressed to find a common battery made anywhere else here in America.

Thank you for the forum sticky and this thread. Excellent, useful safety information. There were just too many things about batteries and chargers I didn't understand prior to this.
Glad they helped. Sounds like I didn't make it overly technical, which is what I was attempting.
Ohhh, how timely for this post to show up. I had just been trying to research info. I just purchased my first Mod - a Varitube-3 kit from Vaping Zone. It's vv and uses 2 Efest 18350 LiMN IMR batteries. They are flat tops. Oh, and the mod uses pulse technology. There was no manual for safety or guidance.
I have a couple of questions:
Should I rotate the 2 batteries in their positions top/bottom on every recharge ? I've only charged them about 3 times, but I did not know about marking and possibly needing to rotate their position.
Are the Efest batteries reliable and safe? They are not mentioned in your list.
Thank you so much for creating this post.

I'm looking at a cell phone charger that has information on "input" and "output". Output for this charger = 5V 750mA. Is this correct then: the charger's output is 0.75 amps, and based on the above info, this charger is safe to use for a battery with a higher amp rating?
Great post op, definitely great information.
Pertaining to the long term storage, you'll notice that cell phones ship from factory anywhere between 40 and 60% in their lithium ion batteries for the exact reasons you've stated. Just throwing it out there lol

If you use it on a 5V battery...
That cell phone probably has a built in regulator which reduces the voltage to the battery when charging it, much in the same way a USB wall charger connects to a USB e-cig charger. if you were to try to use it on a stand alone lithium you would seriously damage it and risk fire/explosion.
Only use chargers made for the battery or device it came with!!! That should be rule #1.

Yes, that makes sense. Unfortunately, sometimes devices only come w/ the USB cable. I have two such devices now and all my attempts to find an OEM wall charger or wall adaptor for them have so far been unsuccessful. That's why I'm asking actually. I'm trying to look for compatible chargers from reliable brands.
if it only comes with a usb type cord,,then any usb type wall charger will work,,ALL usb plugs have the same power supply of 5v.
you can even charge off the usb ports on your computer !!
Position of the batteries is irrelevant as far as I know. However, voltage is important. It must match. That is why they say use them in pairs. One full battery and one empty one is a bad scenario.
I think a battery thread is cool. Directing people to "battery university" is pretty worthless.
I am skeptical of selling people any form of lithium battery with no instructions or a voltmeter. Unless you have some specialty battery, they should always be between 4.2 and 2.7 volts. If you get a bad charger that charges to 4.3, you are at risk of a battery meltdown. If you charge a battery at 2v, the same thing can happen. The charger is supposed to figure all that out for you but the quality control isn't always there.
Over discharge means two things. Going below 2.7 volts or shorting the battery. There is a thread here where someone had a battery get hot in their pocket, but they were carrying it with loose change. They shorted the ends together and they got a warm pocket. That is not a safe way to carry a battery around.
Surefire is not a generic-fire brand. I'm not sure trustfire is actually a brand. The name has been around for years but it is just a name they slap on generic budget flashlights. The weird way lithium stuff is marketed, you have to trust the store you get them from.
Denali_41 is right on - don't know why you can't seem to find one; lots of places carry them. Do a Google search for AC USB wall adapter and you should find a ton. It is possible to rig that cell phone charger to fit on a male USB connector, and then plug in your USB charger, but I;m not going to give out the pinouts, since I don't know your level of skill in this area.
This is a great, properly dumbed down thread. Thank you for taking the time to put it together.
I have a question about the volts on stacked batteries. How much of a difference is too much? I am using 14430 batts that charge to 4.2 volts. So if one reads 4.20 and the other 4.22 is that ok? When is it not ok? I do keep them paired. I have 3 sets that I rotate. One set in the mod, one in the (unplugged) charger, and one in a AA plastic batt case. When they move, they move together so they always stay with their buddy.
Not OK would be one freshly charged battery and one that has been used. Preferably a balanced set is the way to go. But by keeping them in pairs, and fully charging both, you should not have problems. When they start to age (3-6 months or so), it would not be a bad idea to check them with a volt meter after using them in your PV for a little while to see if they are each discharging uniformly.
