The vehicle in question is this one:

Last night I came home from work around 5 PM and noticed that one of the
two Cats they're using for the gas main project in my neighborhood had its
hazard lights flashing. I tried the crew chief's cell phone, but it's his
work cell, and I guess he doesn't answer it after hours. I knew from
previous conversations that they are done at 3:30.

Later, around 9:30, when SWMBO and I were walking the dogs, we walked past
the Cat and I decided to try the door. It wasn't locked, so I climbed in
and turned the hazard lights off. The best I can guess is that they were on
for about 6 hours.

When I left for work this morning, both Cats were gone, so either they
jumped one with the other or the battery was fine.

Anybody know how long the battery in a Cat like that would last with the
hazard lights on?

Your queastion is impossible to answer. Depends on battery size, type
of bulb in flasher, and so on. If they are LED they can go for days on
even a small battery.
