I bought 2 of the 14500 ultrafire 900 MaH batteries and they are giving me a hard time, they only last 2-3 hours of moderate use before dying. On my Ego 1000 Mah with the same stock 306 atomizer it will last for over 12 hours. Did I just get a bad batch of batteries? I have a couple 14500 trustfire on the way, I hope it will be better. I know the AW batteries are reccomended but the usual place I order from dosent stock them.

I know you mentioned that your vendor doesn't carry them but the aw imr is really the best choice. There are a number of posts explaining why. Check out RTD vapor. Good prices, fast shipping, and he's a Reo owner. I have seen people suggest the AW protected before, but they may be longer due to the protection circuit compressing the spring further.
Just for the record, I, personally, can see a distinct difference, between the IMR's and regular LiOn's. I suspect it's because of the high C rating they have ("high drain"), but of course, YMMV.
Nah! I'm barely hanging on by my fingernails (figuratively speaking) when I read most of this stuff. Funny, tho. A "little" of it seems to stick despite my aging brain 
Its going to seem like Im advertising them or something (im not!) but supertmanufacturing has IMR batts and chargers in stock. The have the biggest AW batt selection anywhere. Oh and the lowest price + shipping too. I just placed another order from them

"AW IMR 14500 ***OUT OF STOCK*** More stock expected in on 08/29. 3.7 Volt 600mah"
I had a pair of AW IMR 14500s for my mini and now use the Trustfire 14500s, not a fan of the AW IMRs anymore.
The AW IMR 14500s had a very noticeable decrease in charge life compared to the TFs, I'd get maybe 3 hours of vaping out of one before it had to be charged again. The Trustfire 14500s give me 4-5 hours of heavy vaping, sometimes more, before needing to be recharged. Both my AW IMRs seem to hold less and less of a charge every time I use them, but I have yet to see any decrease in performance on ANY of my TFs.
As I mentioned in my reo noob thread...it is my understanding that the AW IMR is only recommended because the only vent on the reo is the squonk hole which means your hand gets burnt in the event of a battery explosion, hence a safe-chemistry battery being recommended. Is this true? If so, what's wrong with just using a protected li-ion?
I love AW batteries, I'm just not diggin' the IMRs since they don't last as long as their li-ion counterparts.

Here is the reason to use AW IMR 14500's from http://www.e-cigarette-forum.com/forum/ecf-library/129569-rechargeable-batteries.html:
Power rating for rechargeables
The critical factor for ecig mod use is the C rating (discharge current) in amps. The minimum possible value for safe and effective ecig use is 1 amp (= 1000mA) although ideally it needs to be higher. The ideal rating is 2 amps (2000mA) or better as an atomizer usually draws 1A to 2A.
Chart of C ratings vs size
1C or less for low-quality Li-FePo4
Assume 1C for generic Li-ion unless otherwise noted
1.5C for ultra/sure/trust/-fire Li-ion
2C for AW ICR (Li-ion)
3C for BDL 10440 IMR (Li-Mn)
5C for BDL 14500 IMR (Li-Mn)
8C for AW 14500 and 16340 IMR (Li-Mn)
10C for AW 18650 IMR (Li-Mn)
10C for AW Li-FePo4
Note:
Tenergy etc Li-FePo4 (small cells) - <0.55A (~1C - half an amp or less - not suitable for ecig use)
Max drain rate in amps is C in mAh / 1000 x C rating
Example: an AW IMR Li-Mn 14500 battery has a capacity of 600mAh. The C rating is 8C (it can supply 8 times the capacity). Therefore the max discharge current in amps is:
600 x 8 over 1000 (600 multiplied by 8 divided by 1000)
= 4800 / 1000
= 4.8 amps
This shows it has enough beef to safely and effectively run an atomizer - which some 14500's don't. In other words it is less likely to go into thermal runaway if there is an internal fault in the battery and is then used to power a device that draws a relatively high current such as an atomizer; and it will not suffer from excessive voltage drop when powering the atty.
Useful formulas
Amp draw = voltage / resistance
Example: a 5 volt mod is used with a 2.5 ohm atomizer - what current is drawn?
5 / 2.5 = 2
The battery must supply 2 amps.
Power used by atomizer in Watts = volts x amps, or volts x volts / resistance
Example: a 5 volt mod delivers 2 amps to the 2.5 ohm atty - what power is used?
5 x 2 = 10
The atty uses 10 watts
or
5 x 5 / 2.5 = 10 watts
If you are using a 2.5 ohm atty, your amp draw is 1.48 (3.7/2.5)
To supply the power needed to run that atty, multiply your ****fire C rating (1.5) or generic battery C rating (1) times the mAh of the battery, divide it by 1000, and that will tell you the amps supplied by the battery. If it is below 1.48, you will be overstressing the battery
So, according to that information...
AW IMR 14500 = 8c = Max drain rate of 4.8amps
Trustfire 14500 = 1.5c = Max drain rate of 1.35amps
The higher the C rating, the higher the max drain rate of the battery, the less risk of a "draining too much/too fast" scenario which could cause a battery malfunction and/or explosion. Another preventative measure would be the built-in protection seen on Ultrafires and Trustfires, but this protection has a chance of failure which is why the IMRs are recommended. Am I correct so far?
With that being said, and the AW IMR being the obvious safer choice, am I really taking THAT much more of a risk by using the *fire batteries? Safety is definitely the main concern here, but we don't exactly see or hear many reports of *fire batteries blowing up and personal experience so far has shown me that protected li-ions last substantially longer than the IMRs do which is something to consider when used in an e-cig.
If built-in battery protection wasn't a factor then this would be a no-brainer,IMRs all the way...but by going with the *fires I can't really see a downside other than sacrificing an added layer of safety, the need for which can be argued because of the protection offered on the li-ion batteries.
Edit: Also, I'm seeing a lot more about how one shouldn't drain an IMR too much...more so than a li-ion. How would the average vaper know how much drain is too much? I just swap out the battery when I'm not getting much vaper, my 1.5ohm LR306 puts off clouds of hot vapor and if that drops off I know it's time for a new battery. Is this 'system' safe for an IMR?

It's a brand of rechargeable battery, pretty much the best you can get. If I'm correct, they are made by Panasonic. They are more expensive than the common brands you'll see around here like Trustfire and Ultafire, but they're of better quality and the IMR lineup is safer for the reasons mentioned above. They also have a lot longer overall lifetime compared to those other brands.
I had a long answer that got eaten. Yes, for the reasons you noted and because the have been a boatload of counterfeit ***fire batts lately. AW IMRs take 4-5 recharge cycles to reach full capacity. They maintain an effective charge much longer than li-ion batts, so unless you are vaping down to 3.6v, the li-ion shouldn't be lasting longer, even with higher mAh. The li=ion also shouldn't be over-discharged.
Are you certain you were using AW IMRs? the BDLs are a POS, and I've seen suppliers stamping them with a house brand and even a red/orange wrapper.

I'm glad you mentioned the BDLs. I grabbed my "AW" IMRs out of my organizer tray and sure enough, they're orange-wrapped and say...
BDL 100623 100530
IMR14500-600mAH 3.7v
They came with my Reo Mini that I got used in the classifieds, pretty sure the seller listed them as AWs but I'd have to dig up the thread and check to be sure. I guess before I bash the AW IMRs I ought to buy a set of 'em.
Edit: Looks like the seller called them "high drain 14500s" in the thread, so unless he called them AWs in our PM conversations then this one is on me. Whoops.

k, great!! Does this apply to me? Newb with (among WAY TOO MANY other batts) a new epower 45650 and an 18650. want the best bats!
Well, this section is intended for Reo owners and I'm not really familiar with the e-cig model you have...but put simply, this battery discussion pretty much applies to all vapers that use e-cigs that use a removable rechargeable battery. The brands typically recommend are Trustfires, Ultrafires and AWs...the AWs being the best. Generally, you want either a protected Li-Ion battery(trustfire/ultrafire) or a safe-chemistry battery(AW IMR).
Here's a good read on batteries that applies to us all, linked above by mlinky...
