I have no idea on how to update it or even access it, I have some one looking into it but seems he is just guessing trying to help so not really helping
 
Goodmorning all.
Could i start a new tread?
i would like to make a new "processed" section then and keep the old "submission" section open.
I already started to collect data for myself, that's how i noticed.
I also encountered to many "unknown" cells.

But my setup will be in my limits, unfortunately, but with easier search, cous there are to many cells and a lot more cells wil come.
@Wolf his xls is a great setup, i would like to extend that one with his permission, or submit my own on abc order, with manufactuur in a other column.
I will make a trail. if it is not oke you can always delete it.

With best regards Igor

Go right ahead. Nothing keeping you from adding your own view on the data presented :)

It's possible that it may be used later on to update the existing database. Who knows. I don't DBs so I'm not exactly qualified in that department. I barely know how to do spreadsheets :ROFLMAO:
 
Go right ahead
I will

on the data presented :)
Now here is a problem.
I would like to have a dbase (thread)
that Nobody can alter, for safety reasons!

I barely know how to do spreadsheets :ROFLMAO:
Hmmmmm...post this in the humor section....you can work xld ods and what ever better than me, i even think it is your work.
Oke mine is also but a bit more on brickscad and rhino....you know your spreadsheets!!!!

But i will do thanks, if i can have the only right to alter the data base(dbase is short, i know it is a '80 program)

With best regards Igor

Yeah, unfortunately that's not the way the forum is set up. Only way for no one to make changes/add is to lock the thread. But then you'd not be able to make changes/additions to it either.

As far as spreadsheets go, I do a lot of googling the results when I need to accomplish something specific. I know the basics, sorting, conditional, stuff like that. When it comes to lookups, references, etc, that's where I get lost. Back in the day I didn't even bother with the built in functions, I just piped everything to the VBS interpreter and did it in code and then spit the results out to a predefined location. Slower, but worked for me.

UR18650AA - 2250MAH

The main specifications from Sanyo UR18650AA datasheet (pdf):
Rated capacity: 2100mAh at 20°C
Minimum capacity: 2150mAh at 25°C
Typical capacity: 2250mAh at 25°C
Nominal voltage: 3.6V
Standard charge current: 1505mA (0.7C)
Charge end voltage: 4.20V
Charge cut-off current: 43mA (0.02C)
Max. discharge current: 4.3A (2C)
Discharge cut-off voltage: 2.5V
Max weight: 43.1g

The measured DC IR of fully charged cell at 2150mA was 35±2mΩ

red wrap pink insulator, transcuralantish wrap, looks original wrap

Li-18650 ftd 22p – 2200mah?​
Blue​
White​
2200?​
IR?​

Did not found anything about this cell.
~good cells test around 31-34mohm, above 45mohm where 0v cells.
Will keep update
 
Post new submissions here please----->


would like to have specs stating: fabric mah ir charge and discharge NEW
Also pdf with cell specs.
Also if pdf not found and you have 10+ cells tested i would like your testing results incl SOH and IR with MAH per your cells id tested cell

Bonjour,
J'ai acheté sur AliExpress pour une question de coût des cellules 18650 pour modifier une visseuse en Ni-Mh. Après des recherches j'ai commandé des données Samsung pour 3500 mA. J'ai bien reçu des cellules estampillées Samsung référence INR18650-35E SAMSUNG SDI.
Je viens de les tester sur 4 cellules j'obtiens des puissances de 1878 à 1943 mA. Dans votre base de cellules celle-ci n'est pas référencée, une copie ou une Samsung mais bizarre le 35E ? Le plus souvent vendent des cellules roses et blanches copies mais sans marquer Samsung !

Bonjour,
.J'ai recuperé des batteries de vélos HS et j'ai récupéré dedans les cellules 18650. Celle-ci sont des Sanyo et semble par les couleurs correspondent à des cellules référencées UR18650ZY dans votre base de données. Elles ne préasentent pas d'inscriptions sauf Sanyo R1112. Celle-ci ont vécu et présentent des capacités de 1844 à 1722 mA, d'origine données pour 2450 mA dans votre base.

Please use English, if needed use a translator. Google translate does a pretty good job of translating

Good morning,I bought on AliExpress for a question of cost 18650 cells to modify a Ni-Mh screwdriver. After research I ordered Samsung data for 3500 mA. I received Samsung stamped cells reference INR18650-35E SAMSUNG SDI.I have just tested them on 4 cells and obtained powers of 1878 to 1943 mA. In your cell database this is not referenced, a copy or a Samsung but strange the 35E? Most often sell pink and white cell copies but without marking Samsung!

Good morning,.I recovered HS bicycle batteries and I recovered the 18650 cells in them. These are Sanyo and seem by the colors to correspond to cells referenced UR18650ZY in your database. They do not present any inscriptions except Sanyo R1112. These have lived and have capacities of 1844 to 1722 mA, originally given for 2450 mA in your base.

Google translate is OK....... but DeepL Translator is far superior. I have no affiliation. :)
 
Here are some cells that don't seem too great. Found these packs from some kind of hoverboard (?) in the recycling bin. Rather than tear apart I'll try using them as is. All cells were under 1V, so we will see how they recover. Not really power cells, so I'm not too hopeful and am babysitting them. The pack BMS did turn on after I got voltage up over 3V per cell. Only reason I'm posting them is because I surprisingly found data online for them.

Wintonic
INR18650-2000
Darker green wrap color
White ring color

Listed as 1900mAh capacity on the pack, even though cells state 2000.
