R50/53 Does disconnecting the battery mess up the on board computer?

Does disconnecting the battery mess up the on board computer?
Hi guys, I need your advice.
Can you tell me what will happen if I disconnect the battery from my R53 Cooper S, without using any "memory saving" method?
Will I mess up the ECU or other major settings ?
I have to replace the battery but I'm really concerned about this computer stuff... Should I simply replace it, or should I try to keep it "alive" while doing it?
Thanks a lot!

you can simply replace it
I forget if the radio asks for the security code but it won't mess up the ECU
some say it will help it if you leave things disconnected for an hour or so. Search ECU reset. The MINI's computer is supposed to learn your driving style and adjust accordingly. If you buy a used car you might want to 'clear the memory'.

Other than the fact that the ECU won't work at all while the battery is disconnected
(and neither will anything else), no big problems.
You will have to reset your clock and you'll lose your trip odometer setting (will revert
to zero), but nothing else of import from disconnecting to change the battery.
You don't have to do a re-adapt the throttle body or auto transmission shift points
like you have to do with some VWs.
