My 12 Volt battery went bad, bulging sides, Only 2 years old. Replaced with a new Motorcraft AGM H3 under warranty. This battery went bad after two weeks with bulging sides. Battery saver notices showing up on Ford Pass. I replaced it myself with a H4 AMG battery that says it's electric & Hybrid compatible. I also reset the BMS by using the 5 bright headlight switch followed by 3 brake pedal trick. It seemed to reset the BMS. I had to cut off the spacers in the tray so the larger battery would fit. I've attached photos.
