Those are pretty much the same as what I used.



You don't need to necessarily replace the wire, just the lugs on the end.

Replacement lugs are designed to clamp down on all appropriately sized battery wires.

I cut the old strap off, stripped back the insulation about 1/2" and clamped the new lugs on.
Then I gooped it with grease.
