  • Booster cables

    I`m going to make myself a set of booster cables and i`m not sure of the wire size to go with?

    I have a 750 cold cranking amps battery and i want my cables to be 30' feet long.

    Not sure if I need #1 or 2 or even 2 ot wire? I was thinking of buying some of that stranded welding cable??


    Thanks in advance fellas!

    the bigger you can afford the better they will be, your dealing with 12 volts and voltage drop is fast if your pulling 150 to 200 amps, I would suggest the welding cable as well, or equivalent,

    amp chart for welding cable, but remember the voltage on a welder is higher than a car battery,

    check this voltage drop calculator it has 12 volt calculations,

      Get a couple pieces of old welding lead and put some clamps on them and you should be set.
