So got to ask, after you replaced the battery did you also reset the Battery Management System (BMS). If not, it's recommended...

BMS reset - no tools required | 2015+ S550 Mustang Forum (GT, EcoBoost, GT350, GT500, Bullitt, Mach 1) - Mustang6G.com

Yes, I did. Per those instructions.

Do I need to do the battery reset if I just take the battery loose to work on the car?
