I could read battery at address 0x36
chip was not detected, but I inspected it and it is a 045A20
marking on chip is: 045A20 1652 LC014
I could unseal it
But when I try to read EEPROM to back up it, it seems to brick the chip.
now I read it in default address but with wrong data:
after a while I tried again and chip was again readable on address 0x36
I also read it with EV2300 device at address 0x36, it recognizes chip as
045A20 LGC-LNV V041133F4
I tried with other similar battery 01AV420 that I have, which is unlocked, and the same happens, when I try to read EEPROM it hangs.
I have found similar bug in the forum with other Lenovo battery like 01av489:
I will try that solution and inform you.
So this battery 01AV420 behaves same as 01AV489 with address toggling.
I could read EEPROM this way but could not clear errors. However I could write other dump of an unlocked battery and I will try to edit FCC in dump, so I am marking this post as solved.
Address toggle on Renesas chips is not yet supported, thats why described issue occurs.
Feel free to add Feature Request.
