Answer
Hi Tiffany:

What year and model car is this? does it have an anftermarket alarm system or remote starter attached to the car? If so I would disconnect that first and foremost. what was wrong with the battery cables? corroded? if so was ther corrosion on anything else? did the ground wire look exactly as the one you took off? If should have had a smaller wire on it as well that was attached to the body of the car or a clamp on the cable that was attached to the body. if the replacement didn't have what the original did look for the correct cable... Good luck :)
