So now that I have had my 2023 super duty for some time I notice the battery voltage display appears to be more of a dumb display. It only shows 14.0 or 13.0 so far. So I guess charging and floating.
anyone else notice this?

 

I have seen 14.5 at times on mine, but I don't watch it a lot.

 

Same. Always figured it was a rounding error

 

they all do it my guess...my 24 same thing. I got a Banks I-Dash gauge not just for that reason but partially...I think they are super cool. It shows accurate alternator output of course...

 

My 2021 with dual alternators runs around 14.5 most of the time, As high as 14.7 on occasion or as low as 13.6.

I obtain my readout on the banks idash.

 

Using Forcan Lite I can monitor the battery voltage and current. The voltage varies from 14.5 down to the low 13's. The current starts out high but after driving a long way it gets down to 0. I'm guessing a bit on the voltage readings but I know they change on ForScan by tenths - I just don't watch it closely tho.

 

When I started my truck this morning I watched it go from 12.0V to 14.5V in .5V intervals, so it is not a dumb display, it just has a .5V granularity.
