Thanks for the detailed/informative post. I have AGM questions and have read too many incorrect answers from random places on the internet.

Your AGM answers look like you might be able to help. Thanks in advance.Changing from Factory battery (BXT-99RT4-A/ Varta 43Ah 390CCA T4 Case) to AGM Battery (EverStart Platinum AGM Battery, Group H6 (12Volt/70Ah/760CCA)).
Current FORScan settings show the following under the BdyCM module:

· BMS Configuration LIN (Choices are N/A, LIN, and PWM)

· Battery Target State of Charge 120%

· Battery Technology Type AGM (Choices are Flooded and AGM)

· Battery Type Factory Varta 43Ah 390CCA T4 Case

· Battery Type Normal Varta 43Ah 390CCA T4 Case



Note that these settings say AGM even though I’ve looked at the physical battery and it is NOT an AGM battery.



Question #1 – Are these All of the settings that are needed or recommended?



Question #2 – What settings need to change and to what?



For Battery Type (not sure whether to change Factory or Normal or Both), here are the closest choices:

1 – AGM 60Ah 600CCA H6 Case

19 – Varta 70Ah 600CCA H6 Case

35 – Exide 70Ah 600CCA H6 Case



Question #3 – After changing out the battery and then changing the settings above, then I would do the “Battery Monitoring System Reset”, Correct? Anything else?



Question #4 – People talk about a BMS Battery “Days in Service” but I can’t find that setting. Where should I look in FORScan (I’d like to see what it is “now” before changing the battery)?



Question #5 – I have the Varta T4 Battery right now with lots of Deep Sleep and other battery issues. While the car is running, I see battery voltage of 15.0. Is that Good/Bad? [I’m hoping my Bluetooth OBDLink MX+ with iPhone app will let me monitor the battery charge. I’m using the USB OBDLink EX for programming.]
