If you used a 12v battery to jump start the car, this will be perfectly ok as it doesn't matter what physical size the battery is. Somehow you've had a direct short circuit that caused the wires to burn - I guess you had them on the wrong way round. Its difficult to splice these heavy duty cables, and replacing them is the only really safe option.
