Efrain,
          no need to use glue.  Take two cuts through an inner tube.  Open them both out to a circle shape and fit one circle inside the other (so you have an 'o' inside an 'o').  Obviously the fit is not exact (the inner one is a little bent), but that doesn't matter once it is in place.  Take one metal end loop from the existing strap - the loop isn't 'welded', so you can tease it out with a pair of pliers.  Fit it to the 'extension'  Make a new metal loop (I used coathanger wire) and use that to join the 'extension' to the original battery strap.  Does that make sense?
Ian.

Ian, thanks for your comments. I was looking your pictures and your explanation and I don't get your "put one inside the other" part. You glued the two cuts of tube with the metal loops in the middle?

Cheers, ian.  Efrain Baus wrote: Sounds great.
