I am wondering if my voltage regulator is just starting to go out. when I tested it, the voltage was good, but 60 or so seconds of testing isn't very conclusive. not like my battery got hot driving around town. it was on hour 5 or so of 6 hours of driving. I am still going to see if they will exchange the battery, I don't trust it even if it turns out the voltage regulator is the issue. after getting that hot it has to be damaged a little
