Guess he fingered it out!...lol...But seriously, if the car starts ok when cold, why would changing the battery cables help? If that were the problem, wouldn't it be all the time?

Have you checked the battery at all, I sell a lot of batteries lately due to defective battery builds if it is a new battery there should be code stamped in the case that will tell you the manufacture date then you can gauge how long it sat and determine if it was properly cared for while sitting waiting to be sold. I see this all the time a battery can sit for a year before it is sold and it will be recharged monthly to maintain its initial starting load. This can however shorten the life of the battery and buy a quality brand of battery like Interstate, because they will warranty their batteries no questions asked as long as it is under the warranty period. Also a week battery will start great cold and then not want to start after it gets warm from the alternator charging it. Also is the alternator charging properly if not it could be causing a draw on the system discharging the battery instead of charging it. Also in some of these hot rods guys like to add a lot of lights and stereo systems and then an extra battery if so was both batteries replaced at the same time as a weaker battery left and a new battery is only a recipe for disaster later. And the welding wire for battery cable is a great idea we used them at my truck repair shop make our jumper cables for jump starting the larger trucks. Along with carrying more load they are also easier to work with and do not get as brittle as regular wire will after time, and the coating is thicker and will not easily damage and arc on you later.

The battery cables can develop internal corrosion just like on the battery post this will restrict the amount of energy flow through the cables and as they get hot from all of the electricity flowing through them it will increase the ohms of the wire reducing the amount of electricity that can pass through.

Ok...sounds reasonable. I also agree with you that it could be a bad battery. But I guess we will never know since the OP has gone AWOL.
