Don't focus on the actual colours, use them to guide you as to which cells are showing different voltages. A good battery will be the same voltages on all cells, you have cells 1, 14 and 96 that are showing lower than the others and cell 1 is called out as the cell with the worst deterioration in max_cell_deterioration_n. Bad cells have higher voltage when charged and lower voltage when discharged, think of them as a smaller cup that you are trying to put the same amount of water in.
Wizfinger wrote:- Is the max cell deterioration pct value something I can use in my case?
- is the SOH percentage an actual car reading or is it calculated by the app? How trustworthy is this value?
SOH is calculated by the app from the max cell deterioration pct. We believe it is doing the exact same calculation as Kia's tool does. The max cell deterioration pct value comes directly from the car and is something you can use.

Turtle mode is to protect the battery. I'm not surprised that it is sometimes triggering when you have a bad battery.

- am I correct in thinking that steering wheel heating and seat heating also uses the regular 12V battery and not the EV battery?
Yes. The only things that use the EV battery are the motor, the heating/air conditioning (pump and resistive elements), and a DC/DC converter that charges the 12V. These are the 3 things that show on the energy usage screen. Everything else is powered with 12V.
I suppose you could argue that everything indirectly uses the EV battery because it charges the 12V. But then that's like saying the headlights on a gasoline powered car run on gasoline rather than electricity, because gasoline turns the engine which turns the alternator which generates electricity to charge the 12V which drives the headlights.
