New Battery Cable

After my recent exhaust troubles I have found that the battery cable has been melted by close proximity to the exhaust, whilst it has not failed yet, I do not want to give it that chance. So:

A freshly crimped end, with some left over heat shrink to hide the metal

Comparison: Old vs New

I know Green/Yellow is recognised as earth but it was the only suitable cable I had for the job. And by that logic, so is black (the original colour)
