Turned the Jeep off and when I tried to restart it it made a loud noise like the starter does when your battery is to low to crank. Check the battery and it was fine (only 2 months old). Accidentally left the head lights on and killed the battery. I had a a friend jump the car and it started fine. I drove it home and charged the battery. It would not start again with the battery fully charged and I have replaced the start and checked the relay. Still makes the same noise when turning the ignition switch.

Hello,

Have you tried to jump start the vehicle again?
Even though the battery is charged it might bot be sustaining enough amperage when you crank the engine and unable to start it.
I would suggest first try to jump start it again.
Also check the wires that connects to the battery. Make sure the battery terminals are not corroded, which can cause the battery to not to provide enough amperage to start the engine.

Here are couple of helpful articles:

If the battery is indeed good then the next item to check would be your starter and starter relay.
