Will the 21-70 Battery (a.k.a. 21700) Replace 18650?

ok applying my logic
the 21700 will become a household name like AA and aaa (yuck i hate aaa)
i think the general audience has matured to the point they are ready for a paradigm shift in there lives

we Here and in the Vaping world have held onto something for too long and it is time what we know and care about be taken away from us (can you handle that)

up to this point most consumers have never heard of an 18650 or 14500 because it was never meant for them 18650 have been around since 1991
it would be like giving a Light Saber to Jar Jar Binks
but the world is smarter and the chargers are better or the 21700 will be too big to leave in a pants pocket with loose change

i hope to see the 21700 in stores even Kmart soon
i am looking for the ’’That’s one small step for mankind, one giant leap for mankind.”

i have had fun for years ripping apart things for the**_ “Precious bounty” even did a Creative MuVo2 for the 4gb Microdrive _**
but now i only buy NEW TOP OF THE LINE Sanyo/Panasonic NCR18650B and at one point i paid $2,82 each for 50 (now they are hard to find at $4)

but i am trying to say i think 21700 will be come a household word sorry for my rant

The Chinese company Lishen (Tianjin Lishen Battery Joint Stock Co., Ltd.) is getting into 21700 manufacturing.

Their VP is giving a presentation at the upcoming International Battery Seminar in Florida

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.

18650 is very common, maybe as common as alkaline.
But because they are usual used in battery pack nobody knows they are using them.

Well, so much for standardization.

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.

No, not even close.
Even considering the still small amount of people that use rechargeable power tools.

Stuff like phones and laptops and tablets do not use 18650s either.

I read that the 18650 li-ion size is the same as the 4/3AF NiMH cell originally used in laptop computers.

As far as I know, as it says in the OP; the Tesla’s are 21-70, 2170, or 21700…. whatever they are to be called. :+1:

This is 2017.
All electronics devices use flat cells.
Anything still using round is outdated and obsolete.

That is probably the reason ‘hank’ said… “originally used in laptop computers.”

Yes and that’s the reason I pointed out that it is 2017 now and 18650 is irrelevant in modern electronics.

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.

Yes and the point is ‘hank’ was not asking about “modern electronics”.

He said, and I quote……. “I read that the 18650 li-ion size is the same as the ”4/3AF NiMH cell”:http://www.parts-express.com/tenergy-industrial-grade-4-3af-cell-rechargeable-nimh-battery-12v-3800mah-with-tabs—142-0221 originally used in laptop computers.“

He never mentioned a word about “modern electronics”. And I would also bet he knows it is 2017………. :wink:

And by the way, the 18650 is very relevant to what he posted.

What say ye???
Is it the same or not???

Hmmmm, I never really thought about it that way; but that makes perfect sense HKJ!! :+1:

I literally cannot think of one person I know who does not have at least one cordless tool.
And many, myself included; have multiples.

I think you are spot on………… :slight_smile:

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. :wink:

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.

Thank you also…………
