Dead battery

Question type: Maintenance & Repair

A week ago my sister drove my mom's 2012
Hyundai sonata. Was all fine. Yesterday we went to
start it and nothing. The battery was dead. We tried
jumping but could not get it to start. Had dash
lights, air came on, but It wouldn't even turn over
after an half hour of trying to jump it. So last night
we had triple aaa come out put a new battery in.
Now there's nothing. No dome lights, dash lights.
Key fob doesn't work. Won't lock unlock. Doesn't
click or turn over. Checked amps meter says new
battery good over 700 cold crank amps. Battery
reading fully charged. Is there something that
could have happened from previous battery going
completely dead that's keeping new battery from
doing anything?

Check the battery wiring harness, check the fusible lines to the starter solenoid and relay. If there was an inadvertent short of the battery terminals it could have blown a fusible link (Google what those are and where yours are located). I would check around the solenoid for frayed/damaged wiring causing a short.

Check for blown engine fuse in fuse box under the hood.
