My 2024 Prime premium 12v battery died so I had it jumped and drove to the dealer. They checked it and said there’s nothing wrong with it and I’m not using the gas engine enough. They don’t understand the car obviously. The battery gets charged from the traction battery whenever the car is in READY mode. Has anyone had this problem and if so what did you do.
Connect an external battery charger to the 12v battery and fully charge it up. Then remove the charger and let the car sit for 3 hours. Then, use a volt meter and measure the battery. What voltage do you get?
