Yes, my ideas failed! It's just that the board is similar, I thought the chip was the same.

In any case, FZ-VZSU88A2U and FZ-VZSU84A2U originals and FZ-VZSU88U and FZ-VZSU84U with aliexpress will arrive on Tuesday ... I'll try to think of something. With aliexpress, the batteries stop charging and a warning pops up.

 Is it the same warning like on genuine recall battery ?.. 

@djibattworkshop yes

You could disassemble one of AliExpress batteries to check the chips on the pcb.  Sometimes Panasonic aftermarket batteries are easier to reprogram then original. 

the pcb that is in the photo from Aliexpress

 it is definitely genuine Panasonic pcb. 

@djibattworkshop 

This is 150% battery from Aliexpress SupStone Store

It means they sell refurbished original batteries. 

@djibattworkshop 

Perhaps, but the 84U model that does not charge!

Basing on above Safety Notice, Panasonic stopped usage of recall batteries by Bios update release. 

 Have you tried to roll back Bios firmware to let the battery charge ?.. 

@djibattworkshop 

Maybe I'm doing something wrong, but the old firmware is not uploaded.  Bios is already updated.

I also think downgrading the BIOS version would solve the problem.

 Does "Slow Charge" option work on updated Bios ?

Does "Slow Charge" option allow to charge AliExpress battery ?.. 

@djibattworkshop 

On the latest version of the BIOS, the 84U series batteries do not charge at all ... 1% and that's it .... Neither the original nor from Aliexpress. Everything worked on previous versions.
