Are those numbers testing the battery directly using a tool? Or just going off the Battery Voltage EVIC #. My concern was 12v was too low with engine off, but I am going off of the EVIC # alone
Actually its a 12 volt battery and that is where its suppose to be at with no draw from it or juice going in.
If you turn on a lot of accessories you may actually see that voltage drop a bit, with engine off, if there is enough amp draw while the draw is happening.
The battery will return to 12v when the draw stops. The same is true while charging as the volts/amps will show higher volts than 12.
Every vehicle I have had with a volt gauge will show this. My boat shows the same kind of readings.
Unless you are having issues its an inconsequential concern.
Actually it more fun to watch your transmission temperature as that can be very consequential if it runs hot.
On a serious side though, in my opinion sometimes to much information is not good a good thing.
Engine temperature is about the only gauge I pay attention to as needed.
The rest are informational and accessible if you believe you are having problems.
Frankly, other than engine temperature, I rarely look at the gauges, especially the volts. Maybe the transmission temp if I have been towing but that's it.
Too much information..................................
