Does VF ECU or BCM etc. need to be "updated" if a new battery fitted?

Hi,
Just replaced my original battery. (About 5 1/2 years old - 37% health). Does the ECU or whatever need to be told of such matters?
I haven't seen any written advices anywhere. I hooked another 12v battery up before I swapped the old battery out.
All my data - fuel usage, mylink settings, HVAC settings etc. were retained. I have no dash engine fault symbols/codes etc.

Thanks in advance

No. The ECU will work out it's been changed after its done a few trips and gets to know the charging parameters.

No you can just swap batteries without the need to keep the vehicle powered from another battery etc.
The system is designed to have the battery removed, anything important is saved in non-volatile memory so power loss has no effect.

Thanks for the info.
Watching the dash voltmeter, varies from about 12.3 to 14.4 most times on short runs.
My DMM logs about 12.63 overnight no load.
