So thinking about what happened earlier today, the mhd app said battery volts was at 11.4v when the red battery symbol showed up, but with the car still running, the voltmeter said volts at the battery was 13.8. So that would mean the alternator was charging the battery, right?

So I wonder where mhd is getting its battery volt reading from. Because the app said 11.2 and the battery said 13.8. Does that point to bad battery?

I just checked the volts on the battery. When I shut the car off at 4pm today, the battery was at 14.2ish. 7 hrs later it's at 13.37. So almost 1 volt lower than when is that normal?
