so my car has been fine up until now. its a 99 gtp sedan. I drove it to my buddies house, parked it for about two hours, came out and it wouldn't start. It just makes a tik like the starter is frozen. Its got 13.25 volts at the battery but when i turn the key it does nothing. everything else works. It almost seems like the battery is dead but as i already said its not. It has been raining all day in my area, but i don't believe that's an effective variable. Lastly, When i jump it with either a box or another car it starts and runs fine. Could the battery be shot? any ides would be great. Thanks
