I think this is the same cell.

This one is Turquise with a White top ring.
Marking:

ASO FN11024EH 606349

SZN

However, I can supply further information.

This cell comes out of a LENOGE replacement pack and more details about Lenoge here

http://www.lenoge.com/lenogesamsung-8-ce...eries.html

So it seems that these cells ASO   SZN    marked, are Samsung cells rebranded by Lenoge.

Have any of You come across other LENOGE battery packs? If so, what cells have You found inside?

I also liberated some of those turquoise cells:

 

From this pack:



I wasn't holding out much hope for this pack but was reasonably pleased to get between 2100 -> 2200 mAh capacity from the cells. If the label on the pack is to be believed, then they should have been 2600mAh when new.

2100+ mAh is 80%+ cap, not bad from used cells of unknown age. They can indeed be Samsung Cells.  Smile

Maybe we should ask Lenoge, they promise they can provide safety certificates and origin info, but I figure they will only answer if we buy some packs from them.  Big Grin

I have 16 of those ASO (Turqouise) cells Chris codeing slightly differs. came from 2 lenoge laptop replacement packs from a local PC repair shop all tested above 2100 to 2200mah. obviously the battery protection board in the packs were busted!

More info on the Lenoge cells I got:

My batch tested: 2012, 2132, 2139, 2142, 2189, 2237 mAh

PCB is without temp sensors, so it is low cost mfg. and may be the reason for the pack failing.

Seems reasonable to deem the cells 2200 mAh.

I found a few of these. Hopefully they test well.

There are a few Chinese manufacturers (specifically Shenzhen Baiguan Battery Co., Ltd) who produces a few nice batteries.  
From what I can tell, SZN might be an abbreviation for Shenzhen - a manufacturing city in China - similar to LAX being short for Los Angeles, but I don't really know.

My images look very similar to Jeff's above, so I'm not going to post any.

I cannot find the spec sheets for this specific cell, but , they’re definitively not made by any of the so-called respected manufacturers – Sanyo, Panasonic, Sony (Japan), LG, Samsung (Korea), BAK (China), Moli (Canada/Taiwan) and others.  However, they seem pretty good for me.   If anyone can find spec sheets for this specific cell, I'd be interested in seeing them.

Here are some google links and findings I have found this far:
https://www.alibaba.com/product-detail/F...faa6r0jtAo
https://www.alibaba.com/product-detail/c...faa6r0jtAo

Some pretty cool photos on this link too:
http://www.appliances-china.com/supplier...oID=353251

I have a few of these CJ cells shown in the images in the links above also (in blue), but here.  Not exactly the same, but interesting.
the CJ cells are listed as aso/szn  - very curious.

I  have seen published capacity as:
"Nominal capacity - 2000mAh-3000mAh @ 0.2C Discharge"
and others show them to be "2600 mAh"

BTW, the ones I have Mine are purple wrapper with grey insulator bands.
Markings are:
aso gi1i151ef 811563 / barcode / szn
aso gi1i151ef 821153 / barcode / szn
aso gi1i151ef 821100 / barcode / szn
aso gi1i151ef 821142 / barcode / szn
aso gi1i151ef 81153 / barcode / szn
aso gi1i151ef 81153 / barcode / szn
aso gm2l291ef 800613 / barcode  / szn
aso gm2l291ef 800615 / barcode  / szn
aso gm2l291ef 800614 / barcode  / szn
aso gm2l291ef 800607 / barcode  / szn
aso gm2l291ef 800609 / barcode  / szn
aso gm2l291ef 800612 / barcode  / szn

It appears that the third number is the serial number, and the second number is the type of battery:
I have two distinct models, they are:
gi1i151ef
and
gm2l291ef

I pulled 12 of them from a couple of packs this weekend and they all tested really well:
Yes, It seems like the bms board crapped out on them and they sat for a long time.   Charged very well, low impedance, and good capacity.
