The new Tesla / Panasonic NCR18650T1 3400mah is on the market, with more capacity and more power

Tesla has been using 18650 batteries for cars

As far as I know, the Tesla 18650 battery previously known is NCR18650HCL, about 3350mah. There may be an earlier version of Panasonic battery

At present, the latest version of battery is NCR18650T1 3400mah,has more capacity and power than the old version of NCR18650HCL,possible more cycle life.
In terms of positive pole,the old version HCL was inverted triangle and had three legs,the new version T1 is round and has three hidden legs
In terms of negative electrode, both batteries have circles, which is a safety device

As we all know, Panasonic customized the battery for Tesla, which is dedicated to the vehicle. It needs very excellent consistency and high-quality cycle life. It is estimated that it will be more than 1000 or even thousands of times.
Tesla has various programs to control the battery temperature, charging program and output program to ensure longer service life

At the same time, the quantity used is huge and the unit price should be affordable. Therefore, the battery is expected to use ternary lithium battery NCA material to replace lithium cobalt oxide

None of these tesla batteries are found to have specifications at present

NCR18650T1 has a capacity similar to that of NCR18650GA, LG MJ1 and Samsung 35e

T1 is a little more powerful than the latter

Some information is personal speculation, there may be errors, welcome to correct, if there is more information, welcome to add, thank you

The picture shows the relevant battery test curve



Sorry, I don’t know why the original picture disappeared
I re uploaded the picture to Facebook

Thanks TimMc.
It looks like a small upgrade but any improvement is welcome.

3.6V, 4.9A

Vapcell is apparently trying to name drop Tesla…

Are these New Old stock? Are they still being made to go into battery packs for older vehicles that originally used 18650? I thought Tesla was not using 18650 in any new vehicles. IF there are more cycles or better performance in low temperatures or something else that makes it stand out over the other batteries mentioned in the op, then I would consider it.

Wonder what the amp discharge rating is

9

This battery no datesheet

From the discharge test, the power performance is close to GA and MJ1

However, Tesla batteries should pay more attention to cycle life and should be used at low current

I guess the output current of a single 18650 in Tesla’s regular driving does not exceed 3A

I would like to suggest to send some samples of this NCR18650T1 to HKJ for battery testing…

The Model S and X still use 18650 cells.

An updated pack came with 18650s out about a month ago. Maybe it uses the cells Dennis is selling

Model 3 LR, Performance and Y, and Starship booster are 21700. The M3 Standard range in UK/EU/China uses prismatic (brick) LFP cells. 4680 cells are not in volume production, yet.

12

Is Dennis selling this cells? Or he just informs about their existence?

13

Missing the “0” in 18650, date code from 2017?

14

Tesla batteries don’t have the “0”, never did. Their 21700 is called the 2170

15

It should be a new battery. I only met this battery a few months ago

16

Good ideal :slight_smile: we will send samples

So a Chinese manufacturer is calling it a t1. They are showing the same specs as a Panasonic B. Putting a circle on the bottom is not hard for Chinese manufacturers. These may be good cells that you are sourcing. It definitely is speculation that these are coming off the same line or out the back door where actual Tesla cells are manufactured. Or maybe you’re not getting them from China. Yes I’m doing a lot of speculating also. I had not been following Tesla battery issues. Apparently they’ve recently switched to using lithium iron phosphate in most batteries. They are trying to limit how many battery chemistries they have to simplify software battery management issues. So maybe these are some that they’ve decided to not use.

18

This is the original battery cell, not a circle engraved on the negative pole by a Chinese businessman

The positive pole of the cell is very unique, which is not the same in the market

There is a big gap between the power performance of Panasonic B and T1

Tesla still uses 18650 and 21700 lithium batteries in cars, and the energy density is a disadvantage that LiFePO4 batteries cannot ignore

We know that some Chinese companies can and do copy many things. I’m not saying that this can is a copy. I’m just saying that it is possible. I saw the chart that you posted and I have no doubt that it’s a real chart. The company link that LumenMax posted in post 5 above shows a Chinese company listing this t1 battery. And they list some limited specs. And if you go to the Panasonic B battery that they also list you see the same exact specs. They also refer to it as an NCR18650BB. Who knows why they do this. They don’t show a picture of the bottom. You don’t show a picture of the bottom or the top on your website. Like I said above, if it is proven to work better at lower temperatures (0 Celsius) than a LG MJ1 then I’d be interested in it. I’m not biting with one discharge chart. I would suggest that you also send a few to Battery Mooch for testing in addition to HKJ.

There is no reason to call it BB or BG
I have shown the evidence of the outer box of Tesla’s original battery
The name is T1

The battery has been sent to HKJ and Mooch
