Outside of the small group of flashlight enthusiasts, almost nobody has ever heard “18650” and I would be willing to bet about 0.0000001% of the world population knows what it is.
Now you think people will magically need something 10000x less common than an 18650??
Sorry, but no, this is never going to become as common as alkaline batteries. Even 18650 will never become as common as alkalines.
Ask your grandparents what an AA is and they will know, but not 18650 or 26650.
I think all the people in this thread need to get real and actually see what a huge minority they are and how rare 18650s are outside of their flashlight friends group.
Tesla’s got 20700 cells, now this Euro factory is making 21700s.
And isn’t the 3Tron name already copyrighted by one of our own forum members?
But riddle me this - why not make a better 26650, a format that already exists? If you take the 20700’s specs, scale it up to 26650, you’d have even more energy per cell.
Two answers. The engineers wanted this size. Nobody but the Chinese in the last 5 years have made 26650’s. On 20700/21700 standardization 20700 list a 20.3 mm diameter, 21700 list a 21 mm diameter, light junkie’s aren’t even going to notice the difference.
Here is a very interesting SDLE marketing report summary (as of Sep 2016) regarding the replacement of the 18650 format by 20650, 27000, and 21700. It’s a quick read and worth looking at. Lots of charts and graphics. Learned that LG will introduce a 21700 in Q2 2017.
This entire topic is about 20700 replacing 18650 which is why I clarified that it is 2017 and the fact that 18650s in laptops form the past is now irrelevant.
Therefore, it does not matter that 18650s used to be used in electronics because they are not today and will not be “replaced” by 20700.
Did you not read the topic title??
Sure I am aware & did read the topic title…. :person_facepalming:
I guess this means you have no answer to what ‘hank’ posted?? You did read & comprehend that didn’t you??
So be it, maybe some informed person will chime in to either verify or contradict what ‘hank’ wrote.
For us inquiring minds that would like to know that is.
My point is that it is irrelevant to making the 20700 more widely adopted because since 18650 is no longer used there then it cannot be replaced.
The point was not to verify or contradict anything. The point was also not to invite other people to have a useless argument with me when I was replying to a different person that was not you (which is why I used the quote button)
It would be great if you would not jump into random conversations for the purpouse of disrupting a thread and starting arguments…
Thanks.
It would be good if you practiced what you preached also about arguing & disrupting threads. You seem to be pretty good at it yourself. :+1: Seems to me you might even enjoy it.
What I read was a man stated, (in a way that ’to me’ seemed to ask a question); that he had read that the 18650 li-ion size is the same as the 4/3AF NiMH cell originally used in laptop computers.
Nothing more nothing less…… from what I read you did not and have not addressed that in any way.
You informed us it was 2017
You said all electronics devices use flat cells
You state anything still using round is outdated and obsolete
Well the first one is right, it is 2017.
As far as the next two, I think that is a stretch.
It seems to me it would depend on what you considered an “electronic device” whether those two statements are valid or not.
My first post (above his) was “Stuff like phones and laptops and tablets do not use 18650s either.”
And then he replied with his post, “I read that the 18650 li-ion size is the same as the 4/3AF NiMH cell originally used in laptop computers.” which I assumed was a reply to mine.
In which case I explained why it does not matter what they used to use, since 20700 (the topic of this thread) would not replace flat cells in those devices.
In this exchange, nowhere did anyone ask you to make a snarky comment such as “That is probably the reason ‘hank’ said… “originally used in laptop computers.”” when the conversation didn’t involve you at all.
