RFun a search and you'll find several threads on the subject and this just one...http://www.e-cigarette-forum.com/fo...ancy-aw-imr-18650-3-7v-1600mah-batteries.html

Depends a lot on how you use the battery.
To start with, the battery can be viewed as having a finite amount of energy that can be taken out and put back in. Kinda like a countdown clock. If you discharge your battery fully each time you discharge and charge it, you battery won't last as long as it would if you only discharged it a small amount and then recharged it. The deeper you discharge and charge it, the fewer cycles that battery will make. Use it only a small amount each time and the battery will last quite a long time.
But, the way you treat that battery (as in mishandling/misuse) also goes a long way in determing when that countdown clock runs down. Since the AW IMR batteries don't have built in protection, it is much easier to over-discharge them. That will significantly reduce or even destroy the battery. Other factors such as using too small of a battery for the load applied, improper storage techniques such as high temperatures, and improper charging techniques will also significantly reduce a battery's life.
The 18350 IMR battery, if properly used, should last at least 300 or more complete cycles before capacity is significantly reduced. Done every day, that means those batteries should last almost a year before needing replacement. I even have the cheap U...fire 14500 batteries that are used constantly, that still work great and are over a year old. If your batteries do not give you this kind of life, then either you are mistreating them or you are purchasing old batteries. I get my AWs from RTD and have always had good service life from them, too.

Thanks and sorry for the repost, just that I searched and nothing came up... However, this answered my questions. Thing is, i've probably put less than 50 charges on my 18350s and i'm finding that I went from using 1 a day to 2 a day. I haven't been vaping more, but less actually as I used to be able to empty a full 3ml tank and now i'm down to 1.5ml
With correct usage, correct charging, correct storage, and correct care, 500-ish charges before they go below 80% charge capacity is a realistic expectation.
With incorrect usage, charging, storage, care, the service life could be as little as 1 (yes, one) cycle, as there are a few things that can kill a rechargeable lithium cell almost immediately.

Hmm well I'm pretty sure these are real AW IMRs. I got them off another member who I believe got them off ProVape.
The way I handle them is once my ProVari starts blinking, then I pop them out, let them sit a while and then charge them. Then I place them back in the battery box and there they sit on my desk, if not in my pocket being carried around all day. I mean I chain vape like crazy, so that could be why?

Have you checked to see what voltage they are off the charger and at the end of using them in your PV? I had a faulty charger that was over charging IMRs to 4.3v, they lasted less than a few days before I (luckily) checked.
1A is a tad on the high side for an 18350 your battery will definitely benefit from a 500mA charge
No matter who makes the batteries, every day you own then, every time you charge them they die a little. The 80% life figure is ridiculous for vapers
If you are using a pair stacked in VV PV a 5% - 10% drop in capacity/vapetime is no big deal. But in a single cell straight through PV there is also a corresponding drop in loaded/vaping volts. For me once I cross the 5% drop in loaded volts it's time to get new cells.
If you were to check the datasheet of the top tier manufacturers a 5% drop comes rather quickly.
Here's a Panasonic chart.
You'll note in as little as 100 full cycles they are losing steam.
