So, after weeks of searching and searching the internet a lot, i've finally managed to find the (almost) perfect hex code for an EFB 80 Ah 780 CCA battery.
I say almost because the hex is for 800 CCA battery but the 20A difference is within margin of error and the dedicated battery tester show values above 800 anyway.
So, my car is 2019, European ford focus mk4,1.5 ecoblue, 120 Hp.
The address is 726-02-01 and the hex is 0A0A-XXXX-XXXX. IT'S NOT THE LETTER "O" BUT THE DIGIT "ZERO".
I know many were looking for the hex.
Finally - correct as-built value for my new battery (almost)

The purpose is to let the smart alternator know that a different amp battery is installed on the car so that it will charge it properly. I changed my battery from 70Ah to 80Ah.
