changing battery

[nap69]

Hi folks,long time lurker,had a Leon 57 plate 2.0tdi Stylance until just recently and now got a 2015 2.0tdi FR Estate/sportback thing, so just wondering if i change the battery(as it still has the original) will the radio still work? sorry if its a stupid question but had my last car 16 years and things have moved on.When i have changed the battery on other vehicles i had to keep a 12v supply or needed a code for the radio.hope this makes sense TIA.

I have changed battery on my Leon Cupra 2018 without any extra 12v supply. No problems with the radio. Worked without any "code key"

...also code the car for the new battery.
