get a northstar agm G65I upgraded my 05 expo’s 110 amp to 135 from rockauto. 150 for a brand new one. 1-1/2 later still kicking. Any Napa one I’ve used have died every year. Might just be my bad luck. But I won’t buy another reman starter or alternator again. With all loads on at idle 13.5 volts is acceptable. Low. But still charging. Battery should not die in 10 minutes. Get a Interstate mtp- hd battery. Worth it. And will last 7+ years.
