What other batty is the size of a 14500 900mah but has more than 900mah???thats what i ment..

1. Which mod?
2. If you state that your mod ONLY takes 14500 batts, then you've answered your own question.
3. Two 900mah 14500's will last you all day. What's the problem?
4. Get a mod that uses 18650's and be done with it. They last for days!!
Hmm, looking for that too. As far as I understand 14500 is AA size, so this too is an AA size: Amazon.com: Rechargeable NiMH Batteries, 2650mAH, AA size, 8 batteries per pack DC1500: Electronics of course it's NiMH, but anyway.
When you look at battery numbers, 14500, here's what that means. The 1st two numbers are the width - 14mm, the next two numbers are the length - 50mm. An 18650 battery is 18mm across & 65mm tall. Protected batteries may actually be a couple of mm taller due to the protection circuit.
Yes, 14500 == AA size but NiMH run at 1.3v and Li Ion are at 3.7v so you won't vape much if at all with only 1.3v.
Although the 14500 can be compared to an AA battery for size, that's where it stops.
An AA battery is an AA battery and a 14500 a 14500, and as buddy mentioned the voltages are different.
Most "reputable" vendors will have the batteries that they use for their devices for sale on their sites. This is especially important if their bodies are manufactured with close tolerances, e.g all mechanical construction (no spring to take up length) and/or tube interior diameter.
Some will state which battery will work in their devices, and that is the battery that should be used in their device.
If you really want to stick with a 14500 batt and want the extra mileage, build yourself a triple AA box mod with 2 x 14500 in parallel. Capable of 3.7V but 1800 mAh.
When compared to a stock 180 mAh 510 battery, I wonder what all the fuss is about.
Rule of thumb: 1hr use for every 100mAh.
I gotta disagree with this..
most batteries we're using we're exceeding the max discharge rate of the batteries (depending on atty configuration)...
And most manufacturers calculate their mAh using a very low amp draw..
you can pretty accurately figure out close to exactly how long a battery (with sufficient capabilities) will last by figuring out what your amp draw is...
and comparing it to the discharge rates of your batteries...
this can give you a good idea of how many minutes continuous your battery will last.. and if you break that down into how many seconds your button presses are you can figure out how many button presses you can get and then how many button presses you take in an hour..
as a side note: the 900mAh Ultrafire 14500 batteries actually won't last as long as the 750mAh AW 14500 batteries...
NOTE:
Side note in practical use....
ultrafire 900mAh battery has a max drain rate of <1.35A... so it capable of delivering 900mA in an hour or 1350mA in 40 minutes....
Aw 750mAh 14500 battery has a max drain rate of <1.5A... so it's capable of delivering 750mA in an hour or 1500mA in 30 minutes...
a 3Ω cartomizer on a full charge battery (4.2V) has an amp draw of 1400mA...and at nominal charge (3.7V) 1233mA...
So at full charge a cartomizer has a higher drain rate than the max drain rate of the ultrafires..so you can expect about 30 minutes of use out of that ultrafire if you ran it continuous..
the AW probably about 35minutes if you ran it continuous...
now with a joye 510 atty?...that exceeds the max drain rate of both batteries at an amp draw of 1830mA at full charge on the batteries to 1610 at nominal charge...
So with a joye 510 atty both capabilities are exceeded only the AW less so..
Considering the stock batteries (that I've found) for the 510 are around 180mah and run about 2 hours for me, the 2x14500 at 1800mah should be around 20 hours of useful time..right? Sounds good to me....
And if I find out anyone is using a 2.2 ohm Joye Atty on a poor defenseless little 180mah 510 battery and severely overloading it
I WILL CALL PETA.
Do not overload the current rating of your battery.

yes they are severely overloading it...that's why stock 510 batteries die out so quickly...we're overstressing them and killing their service life..
So if my mod takes 1 14500 bat and I vape pretty heavy,can I get 6-8 hrs from it?I was told 2 14500's should get me through the day.Will they?
I have the same question keyzygirl. Just order my new mod and it takes the 14500 battery. I want to know if I need to order more batteries so that I can get through the day or will a couple last me all day?
Happy vaping everyone!!!!
Happy vaping everyone!!!!
Your post LOL
PETAB - People for the Ethical Treatment of Atomizers and Batteries
I almost quit vaping because I bought those poor little batts and I became a chain vapor watching the charger for 4 hours til I could get in another puff LOL. And they never powered up the VG to fully vaporize the ejuice so I got mouth sores.
Amazing that I never killed one...don't report me.

it really depends on which cartomizer you're using and which 14500 battery and how long your button presses are and how many you take on average in an hour say...
here's the breakdown on how to do the math...
Amperage draw= voltage/ resistance
for simplicity we'll just use nominal voltage and a standard carto...
3.7/3=1.23A (1230mA)
now the battery max drain rate..
for example the AW 750mAh 14500 (has a 2C rating)
mah rating * C rating/1000 ...at the same time 60 minutes/C rating
750*2/1000 = 1.5A (1500mA) ...and 30min
(Note: ultrafires have a 1.5C rating...and other Li-Ions can be assumed to have a 1C rating unless specified otherwise)
so you're drawing 1230mA out of a battery capable of up to 1500mA without damage to the battery...and it could do that for 30 minutes continuous...
now at full battery charge your amp draw will be higher and as the battery drains your anp draw will go down...so we'll just stick with the numbers we already have as an average...and since we're not drawing the full 1500mA...we'll say that it could go for about 35ish minutes continuously
so 35 *60 (converting minutes to seconds) = 2100
lets say you take 5 second button presses... 2100/5 =420 button presses per charged battery
so it would depend how many times you push the button
of course all the numbers would change if you use a premium carto or a turbo carto..or using a different brand battery...or how long you press the button on average..
It sounds like 2 will do it,I ordered 4 just to be safe and not worry about charging anymore.But I also ordered 2 3.7 mods so I have backup.I worry about being without my vape.
Thank you guys for helping us figure it out.

yes they would do that..and a good example of how the atty configuration changes things in reguards to amp draw...
LR atty (1.5Ω)...........2.47A
joye atty (2.3Ω).........1.61A
premium carto (2.7Ω)...1.37A
standard carto (3Ω).....1.23A
turbo carto (3.2Ω).......1.16A
So yes the LR atties overstress the 14500 batteries...the joye atties do too for that matter but not nearly as bad...
the trade off for amp draw is the wattage or heat produced...as the Ohms drop the amp draw goes up but so does the wattage (heat) which translates (usually) to the amount of vapor produced..and how long the battery lasts will go down..
