I am editing the post, since eebowler posted the best price. Many thanks to the aliexpress user below for giving us the best price until fasttech showed up :slight_smile:

I didn’t order from fasttech but they say “Authentic Samsung ICR18650-26F” with carrying case just for $5.34 (2-Pack)
-Amazing price for this battery!!!

What confuses me:
The ones sold as “as is” is more expensive.

I ordered these batteries from this Aliexpress user and I did a flashlight runtime test I think they have a capacity of nearly 2450 - 2500 mAh.

They look like are original Samsung. And if they are original for that price it is really a bargain.

Two Samsung 18650 26f for US $10.52 including free registered shipping (very fast)!

My multimeter shows 2.8 A with Xintd c8 v3.

The communication with seller was good, and batteries were very well packed.

Date ordered: 30/08/2012
Received: 12/09/2012

The shipping was very fast.

Some pics:


Update: They are original, have capacity of approximately ~ 2500+mAh. A real bargain for this price!

And about the date codes marcl also asked me that a while ago… I just found somethings but did not understand anything :slight_smile:
(It may be an old - previous version data I dont know)

Nice find but do be careful with Li-ion batteries. We want you to stick around not stick to the walls in case your luck runs out!

3

It is not about luck, use Sanyo, Samsung, Panasonic etc. nothing will happen.

Yeah, but you didn't know it was real Samsung when you shorted them ;)

Too many rewraps nowadays.

But these looks real enough, seems like good batteries and good price. I wonder if this terminates at 4.3V like its bigger brother samsung 2800.

5

No 4.2V

Hi fellow BLFers, any idea how to read Samsung 18650 datecode ?

Recently bought some with FastTech, but not know how to decode, have two with 2D11 & four 2D14

Thanks in advance :beer:

10

You are sure you read the first post? :wink: 2D = February 2013 - I got 6 with 2D14 too

11

“2D11”

“2D”=2013 (2C=2012, 2B=2011,…) “11”=11th week

Correct?

12

2 = month = February
D = year = 2013 (C=2012, B=2011)
last numbers doesnt matter… See Post 1

13

Where?

14

But for 26F its seems to be bit different… Because they only have 1 Line with 4 digits

15

Nothing about year of production. I see only month and day.

edit…
I found these:
http://24x7diy.com/product_info.php/manufacturers_id/17/products_id/185

“2B85”

So 2B=2011 and 2D=2013

It’s very easy to recognize the date code early Samsung 18650 batteries. There’ re 3 lines on the battery body and the third line is the date code.The first digit = Year, the second digit = Month, and the third digit = Week.
However, from the year of 2010, Samsung changed its code rules. Moreover, Samsung lithium batteries are divided into SDI ( are manufactured in Korea) and SDIEM ( are manufactured in Malaysia). And the date code rules of SDI and SDIEM are different.

The battery below is from SDI, and on the second line, we can see “SDI”.
On the third line of the PVC, there’ re 4 digits.

1. The first digit = Version
2. The second digit = Year ( A = 2010, B = 2011, C = 2012, D = 2013, E = 2014, F = 2015).
3. The third digit = Month (1, 2, 3……9, A= 10, B = 11, C = 12).
4. The fourth digit may mean Day, not so sure. It seems that, 3 means the day of 03, 13, and 30 at the same time.

So can be figured out that it was manufactured in July, 2014.

The battery below is from SDIEM, and also has 4 digits.

  1. The first digit = Version
  2. The second digit = Year ( A = 2010, B = 2011, C = 2012, D = 2013, E = 2014, F = 2015).
  3. The third digit = Month ( O = 1, P = 2, Q = 3, R = 4, S = 5, T = 6, U = 7, V = 8, W = 9, X = 10, Y = 11, Z = 12).
  4. The fourth digit may mean Day, not so sure. It seems that, 3 means the day of 03, 13, and 30 at the same time.

Therefore it was made in May, 2013.
