Myfordmobile battery monitor.

What does the mfm battery health monitor actually monitor? Is it 12v battery health or lithium battery health, or both. Right now My car shows the red dot on the app. (car is at dealer still) The lithium battery is showing 98 percent charged. I know that doors and hood are open for a few days though. Could this warning possibly mean that the 12v battery is getting low due to doors and hood being open and such? What does this actually monitor?

Good question. I would assume it would the the HVB but you know what they say about assumptions.....

Exactly, and monitoring the 12v would be very useful considering all the issues people have with it going dead and leaving them stranded.

Every time I've ever gotten a low 12V warning from MFM it's already too late. The 12V battery was 7V or less by the time I got the message.
