Hate to say it but it depends. What the battery is at when it is put on the charger. What the charger charges at. The battery itself is a component.

Did you try putting a multimeter to the battery prior to charging to see what it was at?

A bookmarked page I have that I re-read every once in awhile from the candle light forums about batter charging. Silver Fox sums it up nicely.

How long to charge a new batteries (14500 and 18650)?

Got a new PV itaste SVD that came with some generic looking 18650 2800mah battery. This thing takes 12-15 to charge in a trust fire 3.7 charger. Is this normal?

Maybe, if the output on your charger is only putting out 200-300mah.
The charger should be marked with its output somewhere.
Most of those cheaper chargers put out about 500ma though, which in theory would make the charge time around 6ish hours for a 2800mah battery.
The charger may not be outputting what it is supposed to, or maybe there is a problem with the battery itself.

Your batteries are the heart of your setup. Why use cheap batteries with no brand name of unknown quality by an unknown manufacturer? The same holds true for a decent battery charger.

batteries are not created equal. Generic batteries are REJECTS by other manufacturers which are purchased by distributors who re-wrap them and sell for cheap. Batteries are the last thing to skimp on when you consider they can be one of the most dangerous things you hold every day.

I agree with the above recommendation to go to RTD Vapor and get some quality IMR batteries (AW) and a quality charger (Xtar or Nitecore).

VP1 is very good , but

This apply ONLY to real IMR, or Hybrid Panasonic, Orbtronic ... batteries.

Fastest charger /if you are in a hurry/ is SP2 Xtar. Set it to 2 Amps and load only well known batteries.

Again ONLY real IMRs, and Hybrids.

Anything else you are trying to charge (except 26650 which doesn't apply) do not even touch 2 A setting.

SP2 is AMAZING charger.

If you have cheap unknown batteries for your safety you better charge them 12 hrs.

That is exactly how long will take with xxxfire, and other cheap chargers - because of very low (charging current is shared btwn 2 slots) charging current-which is sometimes very good.
You want to go cheap - then wait. Nothing wrong there.

Edited: I am talking about 18650 IMRs, and Hybrids.

I believe the Charger is at fault the more I read. It's a Trustfire TR-001. The batteries are Blue and say IMR 18650 2800mah. I ordered AW IMR 18650 batteries yesterday. Granted, these read 4.1 V on the iTaste after a full 15 hour charge, and they last through chain vaping for at least 12 hours. But the charge time is excessive. Time of a new charger!

JFYI

There are no IMR batteries with 2800mAh capacity in existence. Be careful because you are probably using ICR batteries.

WRONG! oh so very wrong!

Rule of thumb for charging lithium based batteries is to charge @ 1C MAXIMUM.

Example:
2000 mah battery can take a 2amp charge.
1800 mah battery can take a 1.8 amp charge.

Some advertise as much as a 1.5 C (usually the IMR's)
2000 mah battery can take a 3 amp charge.
1800 mah battery can take a 2.7 amp charge.

when you dip into smaller capacity batterires, that is where we get into problems... Brand of the battery "well known" is NOT a factor for what you set your charger too. mAh ratings is what you should be looking at.

But manufactures usually up-size the mAh rating anyways, so who knows how true any values are. Hence the 1C rule of thumb... jsut to be safe.
This rule is used in RC racing, where batteries take a load of 90Amps during most of its duty cycle.(well mine do anyways)
10,000 mAh LiPo cells are violent when they fail :(
Charging over 1C does give you a quicker charge, but also degrades the battery, lowering its life span, and increasing the risk of battery failure.

The batteries we use for e-cigs, to me, are not considered high performance batteries, and must be treated with extreme care.

The charger the OP is using is most likely non adjustable, and designed to take the lowest capacity battery that will fit... (Example 16340 300mAh) This is for your own safety...

If the charger is adjustable, KNOW YOUR BATTERIES! And be diligent in your research...

Stay safe :toast:

And you trust a guy who states "Do the math and you come up with an average "best guess.""??
I trust the ones who know how and do the actual tests: Flashlight information
But then again, I was working with high performance flashlights about 6 years before I discovered vaping.

I was talking about IMR 18650 and Hybrids.


2 Amp charge - no problem when you are in a hurry - Knowing what battery you have is a must.


ICR you are talking about - different story.

Edited my post to be clear that this apply to 18650 only


Orbtronic 18650 sx 22 will charge at 3.8A ;)

22 Amps Ultra High Drain 18650 Orbtronic SX22 battery li-ion cell


BTW that rule of thumb is wrong and dangerous.

Example - how would you charge Panasonic 3400mAh ? at 3.4 amps ?:glare:

please re read my post, you obviously misunderstood my point.

taken from your link:
orbtronic said:
Standard Charging @ 1A, 4.2V, CC/CV
Fast charging @ 3.8A max., 4.2V, CC/CV

even their normal charging is 0.5C..
but you missed the part of my post when i stated, charging above 1C can degrade the battery causing shorter life span, and possibly failure...

I'm not an expert... but please stop posting about things you have yet to fully comprehend... you got a long way to go.

Besides, believing those numbers on the link you provided, is like believing the MPG ratings at a car dealership...

Time of a new charger!

Yes. There's a reason why TR-001 only cost's about $8 or so. ;)

Skimping on batts or charger, to use with a device you are going to use, all day and every day (not to mention, close to your face) probably isn't a good idea ;) as you have figured out.

Thanks for posting as I'm sure it will help others.

"Protected" ICRs are fine batteries, just not the unprotected ones.

I use AW Protected ICRs all the time, in my 3.7v devices, just not for VV.

(I also used protected ICRs in all my vmods, and once in a while in my REOs, as well as Provape-1, Silver Bullet, Baby Bullets, etc. )

AW Protected ICRs are quite expensive batteries, due to the protection circuitry though. :p

Using mechanicals at 3.7v and using 2.2ohm atties, they are perfectly as safe as IMRs, because you are not demanding a lot of the batteries with a vape like that. Of course, I always meter my atties and batts before using.

YOu could always use a vape safe fuse for extra safety.
