After getting off work yesterday on my way to drop off my son at daycare. My alternator goes dead while driving. My truck has Dual NAPA Legend 850CA and 675 CCA. The batteries we able to last a 10 min drive to the school, restart the truck and 10 min drive to the local AutoZone. They are rated for 110 min reserve. So more than enough to accomplish this. After already deducing the alternator is shot. I have the batteries checked they are about 5yrs old. 1 is good just needs a charge which in the circumstance is understandable and the other tested as bad. But still had a voltage of 11.75V. More than likely that a cell has died. Have done a little research only to find mostly add driven battery recommendations.
So what is everyone else running in their truck and had the best results?
