I'm no electrician..more of Jack of all trades (and master of none) but I do have some experience in this area. Few years back I was jumpstarting my truck from the wife's car and melted the plastic on the handles. Sometime after, I was told that my cables either couldn't handle the load or the battery was bad...well I know it wasn't the battery..it started the car fine. In answer to your question, I will never depend on cheap jumper cables again. Get the smaller number wire..which is actually larger diameter(curious why they do that) and can carry the load. IMHO

As far as connection...you really just have to make sure it makes good contact, $6 alligator clips on the end of cheap wire should connect as well as the ones on the expensive..what matters is what is in the middle. IMHO

$25 may seem like a lot, but trust me...I like know that if I am jumpstarting my vehicle...I don't have to worry if they will work or not. <img src="/images/graemlins/smile.gif" alt="" />
