On my ‘22 I changed the battery type to AGM and I reset the BMS. The BMS reset was probably redundant as I would think that when you change the battery type it would automatically reset the BMS but I wanted to make sure.

use a 1/4 drive rachet and your non-dominant hand and that's about how tight those need to be.

Did this on a friend's Lexus. Battery was very low, her husband was at work, she insisted if we unhooked the battery the dealer had to reset "something". Hooked a garage battery via jumper cables to the car, unhooked the battery (wrapped the positive cable), she ran to autozone to get the battery swapped, then we installed the new battery. Car was perfect, last time she said the dealer charged them for the reset. This is my new procedure, dual battery or not since modern cars have so many electronics.
Ducati, Audi, etc. Also have this issue.
Im fairly certain Ford, does not.
