jumper cables

anybody know what the amperage requirement is for the typical midsize car with a dead battery to be jumped....

I am going to put together a set of jumper cables with knu 1/0 and am wondering how long i could go before having too much resistance or loss on the cable?

why would you waste cable like that?

if they can get away with 16ft at 4awg then im sure you can go up to 30 feet atleast if not more...but why have them so long?

i have had true 4gauge cables before, and they didn't start my maverick (high compression and a dead 65 class battery)

I also will be using them on 2+ battery diesel motors

sometimes it is nice to have extra length

2ga will work fine up to 25ft. I have used them a few times from diesel to diesel. 0ga wire would be a huge waste unless you want to make them 35ft. You can buy nice 2ga bonded jumper cables on Ebay for around $80 shipped, which is cheap. If you make your own, make sure you use high amperage jaws/ clamps.

If you must use 0ga cable, get it from the place below. It will be cheaper than Knu and it's bonded together.
