Which setting should I have the xtar set at for the protected and the IMR 14500s, 1 amp or 1/2 amp?
While I'm asking the IMR 18650s go at 1 amp right?
Thanks in advance.

Well IMRs have a higher discharge rate, but along with that is also the abilty to charge them at a higher rate.
From the main 'office' of AW.
Seems charging at 1A ( which is only ~67% of the max rate) should be fine and speedy.
Thank you for that I was concerned because My Reo mini kept draining them so low. I was constantly hitting them w the meter because I thought it was a problem.
Hey what happens when a battery reaches the manufacturers listed life cycle? Does it just stop taking a charge or something?
Long before that point performance will suffer greatly. As capacity drops so will your initial loaded volts. In a VV mod using stacked cells it just means shorter vapetimes. But in a single, unfettered cell mod this drop in performance and vape quality will start to become apparent much, much sooner.
Check out these charts from two premier manufacturers.
So it would appear the Sanyo has taken a ~10% hit at about 150 cycles.
You will also hear tons of anecdotal evidence of how long AW cells last and why they are worth the money. It's the nature of the beast, every day, every charge sucks a little life out of ANY cell.
When I first heard about the high drain 18650 Panasonic cell I saw this rather amazing test, the AWs look owned.
But I should have paid more attention to the fine print. The Panasonics were new, the AW were not.
Now compare that chart to SuperT's new vs.new test.
The new AWs do quite well, holding a higher voltage over the Panasonics for their stated mAh.
Food for thought.
Generally speaking, 80% is considered the end of "normal service life" and is when batteries should be replaced not just due to the lack of capacity but due to the wear and tear they will have received by this point.
It completely varies and is based on a few factors. With LiFePO4, that would be between 2,000 to 3,000 cycles as lithium iron (not the r) has an exceptionally long service life. Lithium polymer batteries in the Apple MacBook Pro are rated at 1,000 full cycle chargers until 80% of original capacity. With LiMn's (the AW IMRs) like the 18650, the service life would be around 500, give or take. Protected batteries of the same size used to be around 300-ish. However, the new AWs using NNP extends this service life to the 500 mark, give or take. On some of the lower end cigarette-like ecigs, the service life could be even below the 150 mark. On the higher end ones (such as Halo's G6), around 300 is pretty standard.
I was referring to the batts I started the thread about. The AW IMR 14500 and the protected AW 14500. What is AW NNP?
So this is kind of off topic but its my thread so IMO that makes it ok. I just took 2 AW IMR 14500s out of my Madvapes VV Box mod and put them on my XTAR. 1 of the lights would not go red. I took the batt out and metered it and it read 1.01 volts. Holy crap how can that happen. These batts are like 3 weeks old. I meter them every couple of days and have been keepiong a log and like clockwork they have both been perfect until just now. Any thoughts? Obviously this batt is going off to recycle. By the way while you/whoever may be responding to this where can I recycle these batts?
The NNP is AW's new technology on their batteries which has extended service life. On the protected versions, it also seems that they hold a slightly higher voltage under load throughout the entire drain.
Did you clean the contacts of the battery? I am not familiar with the XTAR 2 but it is supposed to be a very good unit. So I imagine it has a general fault notice such as something blinking. If it just would not turn red and it has a general fault ability, there may be something on the contacts preventing you from getting an accurate reading and it getting a charge. If that isnt the case, then it is likely a partially defective battery that only gave out once it was put under load a few times.
If the XTAR detects anything out of place it just stays green which is its standby mode. All contact points on everything are spotless. It must be the battery, its prob gone thru 10 cycles.
I would contact MadVapes and ask if they will replace it. It sounds like it is a manufacturing defect.
I think it was from Super T. I'll have to check invoices. Actually madvapes doesn't sell AWs
My pila charges my 14500's at 600mha. No issue and the charge takes just under an hour.
NNP is Panasonic battery technology, Nickel based New Platform. Higher capacity than cobalt based, nominally the same zone of safety.
PSS is the other new Panasonic technology, nominally similar safety to IMR, but higher capacity (close to cobalt).

My XTAR has 2 options, .5 amp and 1 amp. So for the AW IMR 14500s, the Orbtronic Hybrid IMR 18650, and the Nhaler IMR 18650 I use 1 amp. Then for the AW protected 14500 I use .5 amp. Does that sound good?
That sounds reasonable. Personally I would charge the AW IMR 14500 at 500 mA, under the old rule of thumb (keep max charge current under 1C), but the specific cell is rated for up to 1.5A, so 1A should be fine. (a specific vendor recommendation trumps conventional wisdom on what is allowable, although the 500 mA charge rate would also certainly be acceptable)
