i, being the dumbass that i am, locked my keys in my car with the radio on for a total of 26 hrs. after startin it up once i regained access to my car, it was initially hard to crank up, but has been runnin fine ever since. this happened 2 days ago. is there anything i should watch out for? did this have ANY permanent effect on my battery??

 

No your battery should be fine...probably wouldn't hurt to throw it on a charger for a bit and make sure the water levels in your battery are topped off .
