There are quite a few 21700s I can add (which I also tested). Where can I get the table template to complete the specs in?
 
Hopefully no one is really trying to use these, but I have found some old Dell laptop packs with ancient Sanyo UR18650X9P cells. Yes, they still had a little voltage! (Some also had nasty black spots on the outside of the wrap...) I didn't think to take a picture of the insulation ring, I'll update later with that.IMG_6880.jpegIMG_6881.jpegIMG_6882.jpegIMG_6883.jpegIMG_6884.jpegIMG_6885.jpegIMG_6886.jpeg
 
Hi! Found a new cells that I could not find in the database.

LGAAHD2C1865

Found this cells in DYSON hoower packs. harvested more 100 piece out some low voltage they seem ok

thested many of them about 1900 - 2150 mAh.

Some data on the net ( aliexpress) link

I was just about to add a new cell listing for these cells. I got them from a off-brand dyson v6 replacement battery pack from Aliexpress.

Found a cell that is not in the database. It was in a GreenCell branded laptop battery.
I couldn’t find anything regarding the cell’s specs, but I measured 9 of them (with LiitoKala 500) and it may be useful for someone else:

Rated capacity: 2600?
Measured capacity: 2450-2515 (9 samples)
Chemistry: INR (at least what is written on the cell)

Green Cell is a Polish battery pack manufacturer, and these batteries are most likely only found in Europe.

Here are the pics:

New cell? probably very old?
Could not find much about them.
Here are mine test results with a yr1035 meter and some tested on capacity.

Had 4 of the 2200mAh version in a laptop. Don't remember the brand, but they were good as quality.
 
Sony US18650A ? 1000mAh from year 1992 (Sony camcorder battery NP-500 7.2V 1000mAh 2S1P)

I don't know if they are named US18650A, but I found this thread, where Sony 1000mAh batteries are called US18650A from Toshiba Tecra T3400 battery (PA2481U)

Batterij CF INR18650 3.7V CF204Y 2100mAh
red wrap, white insulator ring
I will update this week with photo's and my own findings (mah test + IR)

Could not find any data specs!!!!!!
2100mAh i found somewhere on the net!!! No specs found

 
And is brother, data is still unknown, i had some very odd IR readings, mAh will follow

cf204y and the cf205j.....probably date. Year of build or mAh rating?
Found some data, must explore more - message to myself

Today I came across this one's removed from a Toshiba 96Kwh power pack, they are red with red ring also and they are marked Sanyo R1112, i search the forum but I can't find it, any help?
found the same ones. same red wrap and same red ring...
But the only inprint i could find was:
K12A imbedded on the wrapper.

Found no data
After testing (around 80-100 pcs) i will report back with IR findings and what I could retrieve at mAh.
Any idea would be welcome

ncr18650ga not red but green.
Would be nice under the sanyo in our dbase!
Same name different cell.

Nominal Capacity: 3450 mAh
Maximum Continuous Discharging Current: 10A
Nominal Voltage: 3.6V
Discharge End Voltage: 2.5V
Standard Charging Current: 1.675A
Charging Voltage: 4.2V
Length: 65.05mm
Diameter: 18.35mm
Weight: 46.5g

Pics will follow on edit mode
 
It seems that nobody is maintaining THE cell database anymore.
Some submissions are over a year of age incl all needed data but not entered into THE cell dbase???
In the mean time keep on posting.
 
Dont get me wrong, keep posting, i am busy!
But if you can please post with pictures and what is/was stated on the pack and if you can find a spec sheet, post it
Also post your own IR with a yr if you have and post your tested mah with ir.
I will make a downloadable xls for all to download and to fil in so i can copy and paste it for all of us!!!!
Some idiot has to do it....

Thanks for your cooperation.

Maybe i can have acces to THE dbase? So i can extend and change THE dbase or create a new DBASE???

With best regards Igor
 
I don't have access to it. I'm not sure how it's being housed or how to update it. That's more of an @hbpowerwall question.
