for lack of better words all this is making me lose my **** lol. Truck is now 3 weeks old, 600ish miles and batt voltage is CONSTANTLY down between 12.2 - 12.6 volts. In my mind, that is a dead battery. I personally have a couple older style load testers. Start by charging overnight, then test once reading 100%. Test reads "weak" but good. voltage was up in 13s that day while driving. Next day, cant get over 12.9. Stop by a "batteries plus" store and have them test it as well. Results were failed battery, 200 less cranking amps than minimal. Had an appointment at the dealership yesterday morning. 3 hours go by and they call me stating battery is perfectly in range and all is well. On my way home from work tonight, back to 12.4 range. I'm not physically having any troubles as of yet, but am dreading that this BRAND NEW truck cant keep a battery at what should be an acceptable voltage. Also, with no traditional alternator, does anyone know if the truck will continue to run if the battery dies while on the road?
