Battery reset

Quite a few weeks ago I was exploring a scan tool on my 2020 Buick Envision. I inadvertently reset the battery. At or around this time, my auto start/stop feature stopped working. And lately I’ve noticed that my alternator is supplying 14 to 15 volts all the time the engine is running. Normal operation was usually 12.8 to 14 volts changing regularly. Although the battery is 5 years old it tests in great. I’m reasonably sure the reset caused this change. I’m really not concerned about this, but am more curious about why resetting the battery would result in the change. I’m not a fan of the auto/start function so I don’t miss that part also. My question is: Am I right by not being concerned by this, and is there any way to reverse this reset (assuming that’s the cause)?
