I was flying from placerville, ca, to van nuys, ca, for a pleasure trip. While cruising at 7500 ft in a rented C172 all was routine and normal until approaching fresno. Very quickly the radios went dead then followed by navigation and ics. All electrical system failed and a vague odor filtered into the cabin. We spotted fresno airport and flew triangle pattern towards the field. Landing was uneventful and a green light was received from tower to taxi forward. Maintenance was contacted and they found the battery had shorted out. All of our information and finding were then shared with the fresno tower and ATC personnel. They were very helpful during the event and debriefing. Cellphone would have been handy. Standby radio would have been handy.
