So bad alternator is a possibility - but the idiot light does not light up - and the AutoZone alternator test was good.
I told my daughter (her car) I was 98% sure it was just a bad battery - but it is possible something else is wrong.
You should read around 14.2 volts or so while the truck is running with a good alternator. See what it reads, bet its in the 12 volt range, which would indicate a bad alternator.
