Will edit post with specifications later, I just have to take piece of paper where I wrote it from my garage. :+1:
When uploaded pictures I realised I forgot to take it with me and it was too late to go get it :person_facepalming:
Very nice thread. Didn’t know it existed.
My last batch was not as worthwhile as past finds. Had 6 die on the charger and several red ones (no markings) generate too much heat to feel safe using, charging @ 0.5A. Have yet to check capacity of the survivors of this batch.
Previous batches were pretty successful with most rate over 2000mAh and 10+ up to 2700mAh.
Will certainly take notes from now on to see if there is info I can offer.
Have used and upgraded several items around the house.
Shark 20V hand vacuum
Portable O2Cool fan
Harborfreight 3W spotlight to 6 cell.
Just install a 5.5X2.1mm connector and use my balance charger on them.
3100’s as in 3,100 mAh You sure about that?
Twelve of them would be 137Wh, which would be well over the 100Wh limit placed by various safety regs.
Edited previous post (one with pictures) with information about cells.
Any info on cells with this markings?
HKGFHT5 032397 and engraved ih shrinkwrap H49A
Look similar to some Sanyo I have but no info…
Got 5 more dead HP packs from a friend so more pictures soon 
New here but I pulled 6x Samsung ICR18650-26D 2600maH out of a Dell PT434 and it read 11.1v 56Wh manufactured Feb 2009
Is anyone else getting charged from their local bulk e-waste centers for these old laptop batteries by the pound? They told me they could sell it to me for $1.20 per pound because that’s what they sell it to scrappers for or so they say. This is the only e-waste center for at least 30 miles and majority of the corporations send their packs to them so they do have many newer ones. That breaks down to less than $1 per 6-cell pack. Is it worth it?

i wound up with 300 6 cell aftermarket packs condaining dlg d18650.
they were all at 3.6x v and testing them at 1a all i tested were over 2200mah.
2 years later ones i have built into items are still fine.
these were new packs that had sat a while then brought for recycling by a business associate.
sold a lot to the flea market flashlight dealers at several large markets here.nothing but good reports.
masione outlet on ebay.
dell e64xx 6 cell “5200” mah
this was a dud pack.seller sent replacement and didnt want it back.
so teardown time!
lo and behold 6 +fp 18650 1800mah green cells.
testing them now but it appears 5200mah is a big fat lie!
edit.these cells are averaging 1811.
cells truthfully marked but pack capacity grossly overstated!
Hi guys can someone help me how to disassemble my defective xiaomi 16000mah powerbank to pull those 18650s inside and determine which one is still usefull. Can anyone share links for pics or videos. Thank you very much!
Hey guys.
I pulled apart a HP HSTNN-LB89. Label was removed prior to me getting hold of it….
Contained 8x18650 cell - marked as ZD ICR18650 SY.
Nothing more……any idea of who makes these ? Only thing i can find online is ZD refering to Zhongdao…….
Any thoughts welcome - they are wrapped in a dark blue.
Thank you for the info. subscribing to the thread.

Hello BLF,
I have an Acer 1810TZ Notebook from 2009, and the Accu-Pack UM09E36 wont charge at Least, so i open it now, after i found this Thread. So i will Tell what i Found, for your List at Page 1.
I found 6 Cells and 4 Of them have 3,48V and 2 have 0V
The Pack was Ratet with 11,1V 5600mah
At the Wrap (Orange) from the Cell it stand Sanyo UR18650ZT N25A
The Internet say: Sanyo UR18650ZT 2800mAh (4,3V)
I have in December giftet my first 18650 Flashlight, so i dont have a Li-Ion Charger right now, i charge at the Moment in the Flashlight(s), so i cant say anything about the Rest Capacity. When i have buy a Charger, i test the cells and post it.

P.s. Sorry for my bad English!
I don’t see the Dell 60Wh Type T54FJ in your table. It contains 6 X LGABC21865 4.35 volt 2800mAH cells. Here is a link to a post on them: Which laptop battery pack yields the best, highest capacity 18650's - #51 by Ansarogu - Rechargeable Batteries - BudgetLightForum.com I’ve gotten a couple packs of these for free from work. I guess charging to 4.2V they will be 2500mAH to 2600mAH and I’m ok with that for free! It sure beats the Crapfires. They come from Dell 6420 - 6430 laptops.
lygte-info.dk has a review of them titled LG 18650 C2 2800mAh (Orange) I cannot get a link to that review to work here for anything.
