A tow company driver was trying to jump start a car that had left the lights on for 10 hours using one of those light weight jump batteries. He goofed around for an hour. I got a set of jumper cables and hooked up the dead car to a Ford pickup with a diesel. That car started right up. I don't know if he took all the energy out of that lightweight jumper battery on the last car he started or if they don't work so swell on a slap dead battery. I do like my heavy duty jumper cables. Belt and suspenders.
