4.5 miles on a fully charged battery is certainly doable.
Just don’t run some errands enroute like Tim’s or HD. (Well, maybe Tim’s drive through would be OK.)
The alternator probably is not dead-dead and could be putting out some juice.
Kinda funny story:
With my dual battery Suburban, one morning it didn.t crank over like it always did. It started fine though but I noticed the dash Voltmeter was ~10 Volts.
The secondary battery had developed a shorted cell and had discharged the primary one. The alternator kicked in and revived both.
I went to my favorite battery place and weirded out the young attendant.
The procedure was to pull into the bay, keeping the engine running, pop the hood and let them start doing their thing, checking the alternator and battery.
I pulled into the bay, shut it off, popped the hood, pointed to the secondary battery, and said: ”Replace It with the biggest capacity battery you’ve got… It’s 10 years old and has a shorted cell.”
The WTF just happened look on his face was absolutely priceless. :-)
I assisted him in changing the battery and let him do his thing checking the alternator after the battery change. Paid up and left a happy customer.
