    Re: Help identifying this chip - battery controller chip ?

    Flashed back the modified content and fitted battery.




    I bought a interposer kit for the battery to move the battery away from the raid card itself to keep the battery cooler - it also makes it easy to measure directly on the battery.


    Raid web bios, everything seems to be right - new data is reported correctly.


    Storage manager in windows reports are ok - battery is now charging with 438mA.


    Battery almost fully charged at 4.1V, charging current is only 55mA and it will now start to discharge.


    Something is wrong, battery capacity suddenly changed to back to 1215mAh.

    Battery discharging and is now @3625mV - fluke measures 3646mV.


    Battery discharging and is now @3567mV - fluke measures 3588mV.


    Battery discharging and is now @3443mV - fluke measures 3443mV.

    Getting worried and turn computer off to save battery as this is a raw cell without protection circuit.

    Now I wonder what would happen if I repogram the lc2401 with same hex code but with code sealed, then software/driver should not be able to change design capacity back to 1215mAh.

      Re: Help identifying this chip - battery controller chip ?

      I don't understand why the software would want to change a design parameter, nor do I understand where the 1215mAh value would be stored. Very strange ...

      Can your TI software change the design capacity back to 1800mAh, or do you now need to remove the EEPROM again? Have any of your other EEPROM modifications been undone?

        Hehe yes it is, it must be software or fw on the raidcard itself.

        I need to remove the chip again, this time just for a test I will let the packconfiguration be 64hex (sealed) and see if the software manages to change it back to 1215.

        I don't think anything else is changed but I will dump the eeprom again to see.

        However my goal was to make use of defective battery packs and it is possible to replace battery and reprogram eeprom when battery pack is defective but then I need to have access to a Sony US503759 a8h 1350mAh or similar type.

        If I keep the capacity at 1215mAh I'm 99% sure I will have no problem re-using these packs.

          Made a new dump of the eeprom, I notice that the chip is now sealed - several alterations has been made by the software.

            Sorry, I don't understand what is happening, or why. :-(

              Ok, I got it working.
              Design capacity is not changed back to 1215 and stays at 1800, after first calibration full capacity is now at 1909mAh.


              After second calibration full capacity reaches 1925mAh.


              Not sure it is a problem with hex code or normal feature of this software but charging stops as 49% but battery status is 'optimal', I will ask at a few raid forums what capacity their original ibb07 stops charging at.
              If I remember correctly turning off automatic learn mode I can charge the battery up to 100% but if status will then be 'Degraded'.

                I think you need to find where the system stores the original parameters of the battery pack. Maybe these are interfering with the current parameters. Try searching your files or registry for the battery's serial number, etc.

                  I ended up with using a htc 1200mAh battery - everything is working as it should, posted a update in this thread link

                  Thanks for the help fzabkar.

                    Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
                    by Bowline
                    My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

                    Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

                    My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
                    The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
                    I have tried multiple different Dell power adapters. My Dell...

                    Vostro 3400 (LA-K033P) won't charge battery, everything else ok
                    by techfreak9356
                    I bought a Vostro 3400 motherboard (LA-K033P) to upgrade over my damaged Inspiron 5593 (LA-J091P) board. Everything else is ok except for the battery. This battery I am using now is already a replacement one since I disposed of the bloated original one. Back in the Inspiron 5593 motherboard, the battery charges fine and is identified just fine. However, with the upgraded motherboard, suddenly the replacement battery is labeled as "Not a dell battery". When I borrow a similar battery from my colleague (which did not have replacements yet), it is identified and charges just fine.

                    HP Spectre x360 -DA0X36MBAE0 wont turn on after battery change - Chip identification required
                    by AJ847.63e
                    i all,

                    Cab anyone identify this chip? Pics attached. It's marked L8=6E 74L.

                    History: laptop came from a e-cycler. Dropped off a few laptops wanting to get rid of them so he asked if we wanted them, apparently he tried swapping the battery on this one and acidentally broke the tip of the battery connector and plugged the battery in upside down.
                    All readings on the battery pin seem normal though (comparing to a working same model board).
                    Connecting the charger you can see the above mentioned chip pulsing so it looks like its going into protection mode, but checking...

                    Hi, so the old battery was getting error stated it's capacity is starting too get low and should be replaced, so the customer bought a new one and replaced it, but the new battery was also getting this notice that it's capacity is getting low and should be replaced, so i took the laptop for testing and the battery is charging at the terminal at 8.03V , the voltage of the battery is 7.7V, and drawing around 600mA when charger is put and the laptop is off...so that should be ok... but the bios system test doesn't recognize the battery and can't do the battery test and so is the hp battery manager,...
