    Hello, I don´t speak Polish so I´ll try English.
    I want to rebuild this battery, and then, reset the eeprom.
    I found this eeprom, that matches my battery:
    https://www.elektroda.pl/rtvforum/viewtopic.php?t=1570294&highlight=u1223&sid=

    Is this the right file I need to rewrite my eeprom?
    I have a T20 programmer ( JDM class) that let me program the eeprom, if I take it out, but, as you can see in the next images, can I use Test points (20 to 22) to do it? (Or by using SB or Be2W, instead of T20)
    And, if I decide updating the battery from 8 to 12 cells, do need to change the bin with the new values, as you can see in the picture?
    Anyway, I can build an I2C adapter, if you need more datas.

    Battery Type: U1223
    Manufacturer: Dell
    Rating: 14,8V
    4300mAH
    Capacity: 65WH
    Cells: 8
    Eeprom:24C01R6
    IC´s: bq8011DBT and bq2931PW
    (You can see all this in the second picture)

    Thanks

    Hi. I speak English quite. Do you want add to each section one cell parallel ? This will cause increase of battery capacity from 4300 ( i think it's really 4400 because each cell has 2200mAh capacity) to 6600mAh. Voltage will be also 14,8 but capacity 6600mAh. Dump file must be prepared to get 6600mAh, but commonly knows where is full charge capacity and cycle count in this case, but don't know where is design capacity. I don't know if you read 24c01 as you described with test points, because bq8011 may has some protection, then you must unsolder eeprom and read/write outside board. To read 24c01 you need sda, scl, vcc and gnd of this eeprom connect to sda,scl, vcc, gnd of programmer. Maybe use sbw interface from this link https://www.elektroda.pl/rtvforum/topic1572103.html
    Before you write other dumps make sure that have original dump saved. Dump from this thread https://www.elektroda.pl/rtvforum/viewtopic.php?t=1570294&highlight=u1223&sid= must be prepared for 6600mAh. I suggest you read dump from your battery, and upload file and I'll try to prepare 6600mAh from your file. Greetings, Kris

    Here is my eeprom (I think it´s a correct reading).
    I´ve used a JDM programmer, because I couldn´t get the 74SL05 today and couldn´t build the I2C interface. I have tried testpoints, but no luck, pin 7 must be unsoldered, otherwise, you can´t get any dump of the eeprom, probably because of the bq8011 IC. Finally I unsoldered completly and used pins 4 to 8 with the T20 Programmer (thanks to Dani for helping me)
    It seems ok.

    Finally I won´t upgrade it to 12 cells, it wil be 8 cells.I think it will be difficult for me to do it.
    By the way, you can see written in the case 4300 mAH, not 4400mAH

    Thanks, Kris, for the file. And if I decide, finally, upgrade the cells, I´ll coment it here. By the way, wich version did you used? Full or demo?
    Thanks again.

    Hello again Kris, I have one more question.
    I reassembling the whole pack (because I don´t still have the new cells) and now, the notebook doesn´t recognize the battery. None information with batterymon.
    I tested it and have almost 15 v ( I don´t remember exactly now) between + and - terminals, but when I test GD and B+ in the battery pins (you can see the pinout in the second pic), I have nothing,no tension or charge.
    Is it normal? May be something´s blocked when I opened the battery, for example Bq ic´s?
    I resolder the eeprom, then, the black, white and yellow wires and finally + and - terminals (old eeprom,nothing changed).i´m using an original charger too.
    Do I need to give some tension to the terminals with a normal charger ( about 4v or so) to inicializate the battery again?
    Maybe something about the black (fuse?) 12A G4 SF?
    I hope you can help me, before getting the new cells.
    Thanks

    Sorry for the delay Kris, I was out.
    I doesn´t still have the new cells, but I tested the last bin with the old ones ( desoldered the eeprom again and reprogramed it again)
    Now, the laptop (and batterymoon too) recognizes it.
    It seems to be charging. I´ll wait a couple hours and will send you a batterymoon screen, with the datas.
    Why now, the laptop recognizes the battery again? What did you change in the eeprom,if you can tell it, of course?
    I´m a llitle scared of charging the old cells with this eeprom, but i didn´t want to leave this post without a reply, while I get the new cells, so I probed it with the old ones.
    Thanks again, and later, I´ll seend you a screen capture of batterymoon.
    Thanks.

    Hi! It's not a mystery what I have changed. In cells 0x06 an 0x07 are changes. You can compare this dump and earlier one. I've got some info if dump is locked, I can try to enter 00 00 in cells 0x06 and 0x07.It's in case with bq8011 and 24c01. Don't worry about charging old cells with this dump. Nothing will happened, because controller is a "guard" and has overcharge and others protection. You can buy new cells now, but remember to write this dump again, because with old cells some changes in eeprom may be added and capacity may drop down.

    Hi. With sbw demo You can only reset bq2040 and bq2060 with 24c01/24c02. BQ8011 and eeprom must be resetted manually.
    Please write here, what capacity can I set for You in dump ? (write capacity in mAh)

    Please notice that your battery has "charging current" and "charging voltage" equal to 0. It's mean that fuse is corrupted and/or controller (BQ8011) is locked. You can fix fuse, but to reset controller you need sanyo tool or something similar. Sanyo tool is expensive.

    You should disconnect cells beginning from most positive to negative, connection in opposite order. Then, you should unsolder eeprom and read it by sbwdemo or be2works. Upload dump here, and someone will reset it.

    Does laptop charge/discharge battery or doesn't ? If charge/discharge, please calibrate battery, and upload here screenshot from batterymon software. Leave battery for charging in laptop for some time, for example 4 hours, state of charge from 0% should grown up to 100%.
