    Is it possible to to tell if this is first or second battery inside the car?

    Maybe the Battery is changed (with new or used) after the car was produced in 2007.
    But if so, it was not coded for battery change!
    Look at the Battery, are there any date codes ?
    Else it would be more than 10 years old!
    From all History files I have, you have the record, in hours below 12.5, 12.2, 11.5 Volt

    It is normal to show Battery sequential number #2 for record 1, 2.., even if it show #1 in Record 5.
    I don't know why.

    Thank you - that was the answer I was looking for. There are no date codes on batrery (or I can't recognize one) and it is original OEM battery (no reason not to be coded - if change done at dealership) - so it is most probably more then 10 yerars old... Low voltages are from playing with VCDS, aside from that battery does well, car starts with no problem, MMI indicator is on 100%, but it feels like it has not much capacity left, because it drains pretty fast (about 1 hour with ignition ON and indicator tells 50%, and quiescent stages DTC's are written)

    So, it is probably time for new battery...

    Something is wrong with this record... More hours (little bit more than 11 years) then the hours passed since the car has been produced (10,5 years)...

    Look at the #8 data. Is from 2017-12-18 and has 75602 "hours" below marked Volts... The difference is around 21000 hours in 7 days... So it must be in seconds....

    I don't think so, it is 5 hours for that date.
    The 75602 is the total hours from new battery.
