Re: Battery/starting issues

If you had one of those meters that clamped over the battery cable to measure amps whilst cranking it would be interesting. A couple of 6v cars I tested (that were working properly) drew in the mid 200 amps if I recall. Will check a couple this morning and report back. No way the battery should drop to 2V after 10 seconds cranking. Or how long does it take to get your car to light?


I'm going to take a moment to rant about battery tenders a bit. They are useful for cars that have computers that draw continually. Otherwise they are NO help, and seemingly a harm. My real-world experience with my collection of old cars over 40 years is that the batteries do just fine over the winter if the car is put away fully charged. Disconnect a battery cable for safety's sake, shut the hood and walk away. I have several batteries that are more than 5 years old, and replaced one this fall that was 8. One car came to me many years ago with a marine battery in it. It went on an extended tour this summer over 3000 miles. The battery date code is from 2002!
