Narrative:
My preflight found a failed alternator belt. In overpriced airport; getting a mechanic or hotel room for a sane price was out of the question. I determined I should have enough battery energy for engine start; radio chatter leaving the airport; and for transponder for the 25 NM to get out of the class B airspace; 30 NM veil. I'm satisfied I did; 'cause when switching on at destination; I had power for radio and landing gear lights. I chose to first do emergency extension to save on battery power. Slight chance I brushed ZZZ's airspace.
