When I sent files as bin, it was reported that it did not support these files

The 1st bin file is from the board where the cells are and the 2nd bin is from the board without cells. I read both chips

But only the file 1.bin is important

So file 2.bin is empty you need to read it again.

File 1.bin corresponds to battery 02K7026 battery part number.  MCU m37516  eeprom AK6480AF Panasonic firmware and has been reset.

Before you write it back erase AK6480AF memory completely, don't just overwrite content!

Today i had the chance to work on such an antique.

The last time i had one in my hands was about 10 years ago.

The chipset is  AS358D + SL394 external eeprom memory on the back of PCB.

So i decided to post the original(locked) & new reset dumps here.

They might come in handy to someone.
