Hello! I’ve been using Samsung 25R batteries in my devices for nearly a year, and figure it’s probably time for some new batteries. I was doing some research and was thinking of switching to Sony VCT5A. When I went to the website to order, I noticed that Sony sold their battery division to Murata? Does anyone know if this would cause any change in the “quality” of the batteries?

Yes, Sony cells are now Murata. I just searched the forum for posts by Mooch (our battery guru, if you're not familiar with him) and the Murata cells he's tested (which do include the VTC5A) have come out identical to the Sony ones.
Where are you ordering them from? There are issues with making sure you have a reliable vendor, so if you have any questions there we can point you in the right direction.

I just picked up some new 18650s last week. Went with the Hohm Stretch batteries. Very pleased with their performance. Last longer than the Sony batteries.
Mooch rated the Sony VTC5A's as 25A/2500mAh and the best overall 18650 batts. I have 4 dozen of them bought way back (under the Sony label). All are still like as good as new after a hellofalot of use.

I have a bunch of other 18650 FT's.... Samsung 25R's and LG HG2's that got it done just fine when I used them more than I do now... and a bunch of Vapcell Black he rated as 30A/2000mAh that I don't use in my top shelf gear.

I’ve ordered from imrbatteries.com in the past. Are there better vendors?
Does that battery have a good rating? I was using some hohm life that were recommended by my local vape shop but then I saw Mooch’s testing and see they might not be as good as they claim?
They're one of the good ones, so you're doing well. Some others are listed at the bottom of this page.
Yeah, I saw they were rated the best all around so I wanted to give them a try was just concerned when I saw the manufacturer changed.
I did see the chart, I just wasn’t sure if it was the most current version? In the past I thought they were good for one month, but this one said from Nov 18 - Dec 19?
Can anyone tell me from experience if there is a significant difference in battery life, safe wattage, etc between the Samsung 25R and the Sony/Murata VCT5A? I vape at 65 watts average with both single and dual battery mods.
It's actually December 2019, so next December, not last one. The "do not share after" date is when Mooch plans to update the chart. Plans don't always go as expected, so sometimes we do use a chart after the expiry date. In any case, the link above is to Mooch's blog where you can always find the most recent version of the chart.
The VTC5A (assuming it is the 5A and not just the 5) has a CDR of 25 amps, while the 25R is 20 A. They both have the same capacity (2500 mAh). That means that with a single battery, you should stick to 60 watts with the 25R while the limit of the VTC5A is 75 w per battery.
Since the capacity is the same you'd expect them to last about the same amount of time between charges. In practice, though, you'll probably get a touch more time out of the VTC5A because you should have less voltage sag with the higher CDR.

Here is a comparison of Murata VTC5A and Samsung INR18650-25R (and VTC5 and VTC6) at 20 Amp load
Look what happens at a typical vaping cutoff though, around 3.2V (about 3.6V when put on a charger). The results change a bit.

I know. I tested the batteries not for vaping. Therefore, the end of the test I always at 2.5 Volts and metering capacity also. But according to the graphs, you can see what capacity the battery will give at the end of the discharge of 3.2-3.6 Volts.
Yes, exactly. I test to below 3.2V too.
It was just to point out that looking at the 2.5V numbers doesn’t always reflect their performance when we use them (with a much higher cutoff point).
If I analyze it in my bare eyes down to 3.2V (most of the mods that are not Mech-Mods) the VTC5A and the VTC6 will give similar Wh for the vapers under 20A CDR. However...sind we don´t vape with continously discharge current, finally the VTC6 can deliver more Wh...

The VTC6 is 15A CDR, not 20A CDR so "vapers at or under 15A per battery" would be a much more appropriate description IMO. But if you vape at 15A per battery, then due to the fact the VTC5A is 25A CDR the VTC5A runs cooler so it ages slower as a bonus, and, there will be added safety as another bonus because 15A is substantially below the CDR of the VTC5A. If you chain vape at 15A, the VTC5A is still the clear winner. But even if you don't chain vape, then, if vaping at 15A per battery, you can still get more vaping time by going for something like, for example, the VTC5D (Vapcell black 25A 2800mAh) instead of the VTC6. That is, among several other choices that would be even better still, assuming you are able to find them at a reliable vendor of course. I know choosing the VTC5D is also assuming you don't mind the price difference too much, but the VTC5D also is approximately 25A CDR so there's this double bonus lurking around the corner once again.If I analyze it in my bare eyes
