This time I’m asking about what high capacity 18650 that is recommended out there?
And from my list, what is go and no go? Capacity vs $$ vs 2600/2800mAh batteries from the same brands.
Samsung ICR18650-32A - 3200mAh
Panasonic NCR18650BE - 3200mAh
Panasonic NCR18650B - 3400mAh
Sanyo NCR18650BF - 3400mAh
Sanyo NCR18650GA - 3500mAh
Hmeng IMR18650 - 3500mAh
I have lots of batteries below 3000mAh, but for my flashlights, I was thinking about maybe using some high capacity batteries (not high drain, but some of the batteries on my list has both HC and HD)
Or is 2600/2800mAh batteries from Samsung, Sanyo/Panasonic, LG etc better to use, or better when you think money?
I’m base my questions around that all the high capacity batteries gives around rated capacity (+/- 100-200mAh)
What do you think, is it worth it using more money on batteries when I have this list now:

I maybe missing some more protected cells?
I am unfamiliar with Hmeng, but any of what you have mentioned should be great provided you aren't buying counterfeit cells. I am a diehard believer in Panasonic Orbtronic, although, for modders, they have been found to have some internal resistance. Quality-wise, you can't go wrong with Orbtronic, and I've yet to see fakes of them out on the market. I also rely on Keeppower and Redilast. Used to rely on Tenergy and Hi-Max, but they don't seem to be as easy to get these days. Samsung has good cells, too, although I've only had a few.
You have a great collection. From what I’ve read, I’d only get Samsung, LG, Sony, Sanyo and Panasonic, in no particular order, from now on. The tough part though, as Rusty Joe said, is avoiding fakes.
You have quite a collection of good quality cells. Unless some are on their way out and no longer hold their rated capacities and need to be replaced - you are sitting good.
It is easy to unnecessarily spend $$ on batteries. If it were "me"...I would not be buying batteries until some vastly great capacity changes were occurring and I needed to replace batteries.
Tnx, this is my list of my brand new batteries, either in house, or on it’s way.
I have not listed my old Trustfire/Ultrafire batteries. Still, I think I have been lucky with the Trustfire batteries, but I have never tested them for actual mAh, I have had some of them for 8 year, and they work like a charm yet.
But they are going out when I get all my new batteries in house.
From my assorted research, I am convinced that (ignoring price and assuming you can charge them) the 4.35V charging voltage cells provide a better extracted energy result. If you look at the curves, the 4.35V cells maintain their output voltage much better (significantly flatter curve) than other cell chemistries. This should provide better total energy and keep the input voltage up on the converters (potentially reducing heat generation in the converter). The converters should dissipate less waste energy in this case. Even better outcome for direct driven LEDs.
Same here, I still have some Trustfires, old ones, from back when they were trusted, ahem. I’ve never had a problem, but it is time to replace them, and I won’t take the chance again.

When was the last time you were using your 18650’s and they all were drained? (needed more?)
Maybe you just need chargers to keep up with you usage?
If you have chargers to keep up with usage then use the cells to the point that you are (appropriately recycling them) do to excesive charge/discharge cycles the Irr is now too high to have them be useful anymore.
I have understand that they can have a “shelf” life of 10 years. So I don’t need to use all right now.
And I have plans to start selling a little, to see if there is a marked here.
