Hyundai: Engine Won't Start

Don't rule out the battery either. I'd be tempted to swap in a
battery from another car.

Considering the fact that the cabin lights and headlights were still
working, I was surprised to find out that it was in fact the battery.
The tow truck guy went ahead and tried a jump start and it fixed it.
Well, I learned =).

It takes much less current to operate anything elso on the car when
compared to the starter motor.

It was probably one dead cell in the battery. You can test for that
pretty easy with a regular voltmeter. Test the battery voltage with no
load(ie, ignition off, lights off). You should see about 13 volts on a
nearly-new battery and no less than 12.2-12.6 on a used battery. It
will drop below 12 volts while the engine is being cranked, but
anything below 8 volts is definately suspect.

It's somewhat unrelated but the original battery on my Kia did exactly
what yours did...started cranking slow. Then one morning it cranked
over and started..barely, and then it threw a check engine light at
me. As it turns out, Kia put a DTC in the ECM for 'low battery
voltage' and I hit that threshold during cranking. A new battery fixed
it right up. Had your car started with that marginal battery you
probably would have had a check engine light alerting you to the
voltage problem.

Actually, a fully charged, properly functioning battery should produce
14.2 volts (2.3v per cell x 6 cells).

You mean I've never seen a fully charged, properly functioning battery in
my 11 years of auto repair. I was taught that it was about 12.8.
Acceptable alternator regulated voltage begins as low as 13.5!

I was thinking the same thing. I've seen them hit 13 volts but never any higher.
