Battery cable size gauge Options

[Harpo]

What size/gauge wire do I need for battery cables? My current one is .35 inch in diameter including the insulation.

This page suggests I need size 0. That seems rather large

Thanks

[When doing a major engine out project on customer's cars I replace the stock cable to the starter with a 1 GA 60 inch cable. These are available from NAPA but will likely have to be ordered. Usually takes a day or two to get it.

I prefer the flat, braided heaviest ground cable NAPA sells i a 9 inch length.

Please remember to clean the metal around the ground stud to ensure an excellent connection.

These two components almost eliminate the need for the hot start relay kit.

FWIW, cables need lots of strands. Most current is carried on the outer surface of a strand of wire. More strands = more surface area = less resistance.
