I'm not sure exactly what settings/data your referencing. Even just a second and the radio presets along with the power window settings are gone. Fairly certain ECU learning/trim data is also gone (this isn't a bad thing) as soon as you disconnect the battery.
If what you're really worried about is losing a tune, don't. As evidence, I've had the battery disconnected for days and weeks without problems. In fact my car has been without a connected battery for the last month and a half due to periodic work I've been doing to it. I have no doubt once I get it back together it will fire right up once I get the new PC680 battery installed.
