Test/Review of Sony US18650VTC6 3000mAh (Green)

Just got home from my hike w/ Capo,they sold 90 batteries in 1.5 hours! 594 now!!

I forgot about this. I hope it does not hold true with mine.

VEN is from England and on CPF.

Still waiting for my battery man to get the vtc6 anyway, as they are grade B right now(unknown age/storage conditions i am led to believe). So he would not buy any from his HK source/warehouse.

As long as there at there original voltage prbsblt be just fine. You know a difference in grade a and b can be like 30mah difference from manufacturing specs. The cells are fairly new I believe they couldn’t have been stored that long to really make a difference. I have some old sony laptop pulls with at least several hundred cycles that just won’t die. Still crank out 5 amps and maybe a 150-200mah capacity loss from original. I will give Sony that. They make a solid battery

Lately , i have seen a big difference in amp draw , from 30Q (from different batch each one ) .

Older 30Q’s give 250-300mA more , compared to newer 30Q’s , in the same setup .

I have 4 coming my way , so i will make a little comparison when they are here.

They have 523 right now, they had 200 more 12 hours ago.

I picked up a couple as I didn’t have any…. and it sounds like they will be very difficult to get.

Yeah this is what I am thinking too. I can get 4 30q’s for about 17 bucks.

With good free advertising here and other forums it is no wonder they will sell out.

Tesla will have on completion the world’s largest battery manufacturing plant near Reno, Nevada, and it will be in NASA’s own backyard.

True!!! Down to 435! They had 714 When I bought mine last night @ 7pm! They should donate batteries to us for this FREE advertizing!

Maybe it will bring american lithium battery prices down when its operational. If the Chinese can sell to the us in bulk at 1-2$ . maybe wishful thinking but hopefully it will make prices lower. I think its interesting no one has biiolt that plant sooner. Isn’t silver run nv or whatever it’s called the largest deposit of lithium salts in the world? Lithium only forms where volcano’s were st some point

Illum now has the VTC6 in stock for $9 each, for those who didn’t rush to order from imrbatteries.com and paid more, (like I did :person_facepalming: )

I know for Tesla and its plans fella .
Just as Sony is a company that did not expect to leave the field after so much progress in 18650 .
The truth is that stated Older that will stop the manufacture of Li-Ion 18650 and will deal more with LiPO, but then we saw the VTC5A and now VTC6.

I wish not to stop to compete and naturally …… best prices ……………

Thank you.

There will a big market for all battery technology in the future.

They got them on 8/26 and were gone last night on 8/30!!! :wink:

I charged up 4 VTC6's and tested in my BLF Q8 SRK cone prototype (k - nothing like the real thing, but using it for the driver/firmware and about the same output), and I got maybe marginally better amps and output than with VTC5's and 30Q BT's. Really can't judge them by this superficial test/compare though, but I'd say their in the league - that's for sure. Had them charge to about 4.21v, bout the same as the other cells I tested, but I did run the light for a good 30 secs before doing the test. Technically it's not head-to-head equal because of that. Usually in the first 30-60 secs at full charge of 4.20/4.22v, I see a drop in DD lights you can't recover. So there's potential of them marginally beating 30Q's.

Right now it's hard to justify cells marginally better for twice the price, but up to the buyer - look at the discharge curve for the currents you are interested in, and compare. They seem to align with the 30Q's, just a little higher voltage thru-out.

The market is a strange place, when supply and demand becomes an abstraction critical thinking sometimes lacks in current. :slight_smile:

In one aspect I am NOT impressed with these batteries at all. They have been used 5.5 months.

One has 40 cycles and the other 20 cycles. Once they have been below 3.70V for testing. Other than that they have NOT been below 3.8 Volts!

BOD: April 28,2016

Purchased: August 22,2016

One came off of the charger @ 4.20v,the other @ 4.19v. Eight hours later they were both 4.14v. When they were new, which was not long ago[!], the resting voltages would be 4.18/4.19v Five or Six days later.

I realize ALL batteries drop several Hundredths of a volt after resting. IMO these have dropped too low of a voltage/too quickly compared to ALL of my other batteries that are much older. If they were a few years old it would not concern me, but they are not.

AS FAR AS I KNOW THEY ARE GENUINE WITH ALL THE CORRECT MARKINGS. I BOUGHT THEM FROM A REPUTABLE DEALER.

Is this a sign of them DEGRADING too fast? I think it might be.

I have many batteries of all sizes that are b/w 1.5 and 3 years old whose resting voltages are higher after sitting for several days!

I see this regularly, particularly with sony cells. They just don’t like maintaining 4.2V for some reason. They tend to drop down to around 4.15V or so and then maintain that for extended times.

This is not an issue IMO as there is only a very minor amount of capacity gained over 4.1V. Heck I generally only charge my cells to 4.15V. I hate using my VC4 that charges to 4.22V.

Wolfdog , some chargers drain batteries if you don’t remove them after charging .

For example i have an Opus bt-c3100 v2.2 that charges batteries at 4.18V and if you let them for 8 hours they will drop 0.02 V more .

I understand what your saying. However, I treat these batteries the same as all my others. Shortly after they are charged I remove them.

In regards to what Texas_Ace is saying about this is typical of Sony cells:

I just checked my VTC5 that has been idle for 5 days and the voltage is 4.16v. This cell will be 2 years old in May! My experience has been different w/ my other VTC4/5 Cells.

As long as they do not keep declining, I will not be concerned. However, every other battery[much older than this] that starts to degrade, the resting voltage gets lower and lower as time goes by!

To cap this off. I have 6 X Orbtronic 18650 3400mAh that I purchased on 12.21.2012!! They have had over 400 cycles and their resting voltage is 4.14v to 4.16V AFTER 2 OR 3 days!
