M6 battery

Trying to get a gauge here on what is too low voltage for the battery either running or off? Thinking this may be causing my problems with misfires/keyless/autostop/etc

I’m look at 12-12.5 when off and 13.9-14 when I turn it on

that sounds about as spot on as one could ask. Any time one of my bmw's had a battery issue it made sure to inform me of the condition. Certainly not the most authoritative source on testing but the video is recent and Sam is good edutainment.

Sorry I meant to say 12-12.15 when off not 12.5. From what I’ve looked at that seems to be on the very low end. But none of the regular signs are there such as headlights being dim or car starting rougher
