Try disconnecting the ground/negative cable off the battery for 30mins and reattach and see if you can get it work.

your cables are filthy with corrosion. need to be sparkly fresh if all those amperes can make it safely to your starter motor. Borrow a load tester and see if this battery isn't too far gone (after fully charging it for twelve hours). Why the hell did it die, in the first place? left your lights on? 2003-2013 sounds like a nice productive life, perhaps it's time to retire this old battery. like I say full charge then load test...and you'll know to buy a new battery or make do with what you've got.
