Battery difference - W126 vs W126S

I'm only days into this (new to me) format, but I read on BHPhoto that the S version improves on battery heat, compared to the original version of the battery.

Yep. It's the heat issue. The new processor is working harder and generates more heat, especially with 4k video and Acros film simulation.
Not a huge cost difference. The battery probably lasts longer, too, since it stays cooler. Probably worth it.

The NP-W126S is the improved version of the NP-W126. It was designed for better thermal characteristics under the sort of load an X-T2 would subject the battery to when shooting in high burst mode or in shooting 4K video.
Note that the NP-W126 version is being phased out.
It'll be interesting to see if third party battery manufacturers create versions of the W126S that perform as well thermally as the W126S. I figured I'll use genuine Fujifilm NP-W126S batteries inside my X-T2 and continue to use 3rd party batteries for my other cameras and maybe for my grips.
Do you have a source for this?

I spoke to Fuji in the UK about a month ago. They said it was not going to be available anymore. They said the 's' was its replacement and would work on all older cameras that took the last model batterie.
Interestingly they said the increased burst rate of the X-T2 was due to the batterie alone. That is to say even with the grip if you didn't use the 's' then you wouldn't get the higher burst rate. Also the camera would overheat using 4K if the new batteries were not used. The new batterie has an 'extra cell' that aids in heat dissapation.

they certainly didn't add an extra battery cell so what sort of 'cell' are they talking about.
My hunch is that the S battery is simply made w/ 'better' battery cells which do not have as much loss (internal resistance) under high load. Those cells are more expensive to produce or the mfgr places a price premium on them.
The history of lithium cells is one of manufacturers playing leapfrog as they (and their chemists/engineers) tweak cell chemistry in a variety of ways. Those tweaks eventually become the standard for manufacturing efficiency.

Its not true about the burst rate so I wonder about the rest.

NP-W126S Batteries Test: Capacity, Temperature and Quality compared
The original Fujifilm's batteries for X system camera are expensive. That's the reason why there are so many alternatives available, but it also makes the choice of the right one tough. They not only vary in
ultralightphotography.net
in the UK we can get the expro white which has 95% of the performance and similar heat to the oem battery

I have a bag full of 3-year-old Wasabi Fuji Knock-offs for 1/4th the price. They work great. Batteries from the camera maker are the last great rip-off in the industry. Batteries are commodities now. Just get the cheap ones. I spend a fortune on Fuji gear. But I refuse to pay 75 bucks for a simple battery. They are all the same. Trust me.
Oh boy .... I can feel another long battery thread. Somebody is going to say they explode or that they would never trust a knock-off in their precious Fuji body. Please..... spare us that nonsense.

Search for Fujifilm NP-W126 on B&H.

But make sure you get the good/reputable cheap ones. I bought some "house brand" batteries from some popular resellers and they had half the battery life and all of them swelled within a year and became hard to remove. IE, not all batteries are created equal.
They absolutely are not all the same! I can vouch for that.
I now have some Watsons for my X-Pro2 and they've been pretty good so far. Not yet a year on them, but battery life is equal to my OEM. By this time next year, we'll know whether the OEM or Watson's are better.

For me the question is whether or not the old third party batteries are going to perform as long as Fujifilm W126S batteries before the camera overheats when shooting 4K video or endless bursts in the X-T2. I bought two extra W126S batteries for those times.
I fully embrace using 3rd parties otherwise, which for me is like 90% of the time. No matter the brand, you still have to be careful with Li-Ion batteries.
No matter the brand, you still have to be careful with Li-Ion batteries. Try not to drop them too often. If the battery casing ever starts to bulge, stop using them.
I've had this very experience in an Olympus.
Yes, this is the point that's important to make. They're definitely not all the same, and It's not helpful advice to say they are.
