Well, it was more half charged and less than a full charge, and it turned the engine over at a good clip. So, maybe it was 66 2/3 or 80 percent – it doesn’t really matter. The fact is; it was low enough not to start the vehicle, but high enough to turn the engine over fast enough that your wife wouldn’t have noticed the difference in the cranking speed.
I have a load type battery tester and the battery tested about ¾ of what a new and fully charged battery should test at under load. So, go figure.
If diesel engines are such good performers, why don’t they run them at NASCAR??
