Remember though, that the 3100mAh use NNP technology. This is not so good for high drain, and the battery still has almost half it capacity left when its voltage would indicate it was empty when compared to ICR li-ion. Your high power lights may not get the best out of it unless designed to do so, so the new Fenix cell, which should deliver the specification as a minimum, should be a good one.

Of course the price point is important, and I'd be interested to see how long the TK21 will run on Turbo using Fenix's own 18650.

How do I know if my flashlights are "high drain", mostly all Fenix listed in my signature. And my batteries are all 3100mAh, AW and one Eagletac.
Am I loosing something using these?

High drain is a relative specification and not that useful.
What you need to know is the maximum current and minimum voltage the light will work at, then you can select the best battery.
In the last part of this LiIon test summary I have given some general guidelines for estimating these value.

I do hope to include the Fenix battery in my comparison, but I have not bought some yet.

Has anyone tested these batteries? Im looking for a good battery for the tk35. Anyone using them.

I just bought 4 of these Fenix arb l2 3.7v batteries and I'm having a problem with one of them. When I charge them they read 4.2v on a full charge with 3 of the batteries but 1 of them reads 1.4v and it always says that it is already fully charged on my charger but the battery wont work... I hope Fenix helps me out directly without having to go through the dealer. It is for my tk75. Any opinions or is this dangerous for this battery to be in my possession? Thanks guys.

If one is reading only 1.4v I would definitely not use it in series with other 18650s. The batteries have protection but still it's not worth the risk.
What charger are you using? It might be that the protection needs to be reset but it's strange that the battery is so low out of the box. It seems you got a defective battery.
You could try to put into a single 18650 flashlight and see if it lights up - with the battery at 1.4v I don't think it will. Just remove the cell after the test.

If you just bought this ARB-02, the dealer should simply replace the defective battery. That would be a lot quicker than getting a new battery from Fenix. In any case the warranty for the battery should be one year.

I got a new arb-l2 and now they seem to be all good. I charged them and when I tested the voltage it was 4.21v on 3 of them and 4.19v on the other. Also my charger is the jetbeam i4 pro. I wish I had a 1 cell 18650 light but I don't. I will purchase one someday.Thanks for your reply and help. I appreciate it.

I find it humorous that they say that the battery has passed the following certifications:

1) UL (The individual cell is probably UL certified, but the product as a whole, I doubt it. The UL logo also is fake. The real one the text is not slanted / italicized. UL logo's here.)

The ARB-L1 that's on the market complies with all UL 1642 single-cell tests except the impact test, as you can see at:

First post, so apologies if my etiquette is wrong, but UL certs are trivially checked, so there's no need to make assumptions.
