Got home after a 3 hour drive and a 14+ volt charge. I pulled out the tester and the voltage was just over 12. I tested it and it loaded to 525 amps. It's a 780. Yep, it needs a battery. 6 years and it's time. With the auto stop it has to be a little hard on it (and the starter) Oh and it's a AGM. Advance Auto down the street has one. Clarios makes them. They also make Die Hard and Delco. That
s what I'll get. At least if I have an issue there are stores around where I can get it checked and warranted.
