They’re supposed to use a robust power supply, not a trickle charger.My 2021 Mach-e got 25S65 update at the dealership a few days ago. The service manager noted that the 12V battery's State of Charge (SOC) was in the ninety-ish prior to the update, but dropped to the eighty-ish afterward, despite using a trickle charger during the process. He mentioned this isn’t the first time he’s seen this happen, but he’s unsure of the cause. Any thoughts?"
Thank you!
