When I diy battery replacement (Autozone & Advanced Auto will not install on my GLC300), I connect a battery charger to the car while the battery is being changed. Serves the same purpose.One convenience thing when changing batteries is if they put a battery tender on the car while changing out the battery. This keeps that status in the car computer and may save presets in the radio if it still has volatile storage for that. It is a simple OBD II connector connected to a small battery that they connect when changing the battery. They have to be careful not to let the positive battery cable touch bare metal because it is still live with the main car battery out.
I would expect most service bay places to do this. Batteries Plus did it on mine even though it was in their parking lot. Not sure if a car parts place would do that or not.
