This was the message I got on the display today, battery seems to be at 0 %. The strange thing is that two days ago after parking the car, I opened the trunk and removed the power plug that I assumed would completely shutdown the car, and then the battery was at around 24%. So the battery should not drop 24 %??? Anyone knows what is going on please? I have previously reported that the car would sometimes not go to sleep and drain the battery when parked and not plugged in: Roadster Radio not working and past few days Battery life dropping 5% per day - Page 4 After the "ESS: Extremely Low. Begin Charging ASAP.", next was "SWP: Aux Battery Supply Low". Would replacing the 12 volts battery fix this issue? I also got "VMS: Battery Discharging During Charge" and charging stopped, but I tried again and then charging seemed to work, so right now the car is hopefully charging.
